General safety precautions (For users)

Like other types of large power equipment, the UPS and battery circuit breaker box/battery cabinet contain high voltages.
This equipment meets the IP20 standard, and other safety panels are fitted inside the equipment.
The UPS may be operated in complete safety, provided the general instructions and the steps recommended in this manual
are followed.

Multiple power inputs (For users)

This UPS system receives power from more than one source. All DC and AC power sources must be disconnected before
servicing.
This UPS includes several circuits that are energized by high AC as well as DC voltages. Check for voltage with both AC and
DC voltmeters before working inside the UPS.

User serviceable components (For service personnel)

All equipment maintenance and servicing procedures involving internal access require the use of a tool and should be carried
out by trained personnel only. There are no user-serviceable parts behind the covers that require a /key for removal.

Battery voltage: 320Vdc - 540Vdc (For service personnel)

All battery maintenance and servicing procedures require the use of tools and should be carried out by trained personnel only.
Take special care when working with the batteries associated with this UPS. When connected together, the battery terminal
voltage will exceed 320Vdc and is potentially lethal.
Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the vicinity of, a
large bank of battery cells. These precautions should be followed scrupulously at all times. Special attention should be paid to
the recommendations concerning local environmental conditions and the provision of protective clo thing, first aid and fire-
fighting facilities.

When the internal fuse of the UPS is damaged, it must be replaced with fuse having the same electric parameters by qualified
personnel.

The area housing the communication board contains static sensitive components, therefore it is necessary to adopt all the
appropriate ESD-proof measures before accessing this area.

In order to satisfy the conditional short circuit current rating, Icc at 10kA symmetrical rms, the specified upstream breakers
must comply with an IEC 60947 series standard.

The UPS is unable to automatically isolate the neutral connection, ensure to have 4P breaker upstream and downstream the
UPS in case of IT distribution.

Chapter 1 Overview
This section provides a short introduction to the Liebert S600D 10kVA - 20kVA UPS (hereafter referred to as “the
UPS”), covering features, design concept, parallel system, operating mode, battery management and battery
protection.

1.1 Features
The UPS is connected between a critical load (e.g. a computer) and the mains power supply to provide high quality
power for the loads. The UPS provides the following advantages:
⚫ Increased power quality
The UPS protects its output against the variations in the input power supply by means of the intelligent controller.
⚫ Improved noise rejection
Due to the use of AC-DC-AC conversion, noise on the input power supply is effectively filtered, so that the load is
provided with a “clean” power supply.
⚫ Mains failure protection
If the input power fails, the UPS switches to battery operating mode so that the power supply to the loads is not
interrupted.
⚫ Compatible with two output modes
3-in 3-out (factory default) and 3-in 1-out (by installing an optional 3-in 1-out copper bar kit). Only authorized
personnel are permitted to change the wiring method and modify the corresponding parameters using the VERTIV
setting software.

1.2 Design Concept

System Design

This section introduces the working principle of the single UPS module. The UPS adopts AC-DC-AC conversion (as
shown in Figure 1-1). The first stage conversion (AC-DC) uses a three-phase, high frequency rectifier to convert the
three-phase input voltage into a stable DC bus voltage.

9
 S600D
Input Output

Battery Battery charger

Figure 1-1 Block diagram illustrating the working principle of a UPS single module

The UPS has its own battery charger and adopts advanced temperature compensation technology to effectively
prolong the battery service life. The inverter is principally based on the use of large power IGBTs, and adopts
advanced SVPWM control technology to reconvert the DC bus voltage to AC voltage.
When the mains is normal, the rectifier and inverter work together to supply the loads and charge the battery.
When the mains is outside normal limits, the rectifier stops working, and the battery supplies power to the loads
through the inverter. If the battery voltage falls to end of discharge (EOD) voltage and the mains has not yet
returned within the normal limits, the UPS will shut down (if the system uses split bypass configuration and the
bypass is normal, the system will transfer to bypass). The battery EOD voltage is pre-set. When the mains is
abnormal, the battery will continue to supply the UPS until the battery voltage reaches to EOD level, whereupon the
UPS shuts down; this period is known as the 'Backup Time'. The duration of the backup time depends on the battery
capacity and the loads.

Bypass

Thanks to the intelligent control function provided by the ‘Static Switch’ module (as shown in Figure 1-1), which
includes the controllable electronic switch, the loads may be supplied either by the inverter or the bypass. Under
normal operating conditions, the loads are supplied by the inverter, in which case the automatic inverter switch on
the inverter side is closed. In the event of an overload (after the overload delay period has elapsed) or inverter
failure, the inverter switch is opened, and the 'Static Switch' module transfers the loads automatically to the bypass.
In normal operating state, in order to guarantee the uninterrupted transfer between inverter and bypass, the inverter
output must be synchronized with the bypass.
Therefore, when the bypass frequency is within the synchronization range, the inverter control circuit will
synchronize the inverter output frequency with the bypass frequency and phase.
The UPS is also equipped with a manual maintenance bypass switch that can be used to shut the UPS down during
maintenance. In this condition, the bypass will supply the critical loads directly via the maintenance bypass.

When the load is supplied by the bypass or maintenance bypass, the power quality & availability will be unregulated.

10
 S600D
System Control Principle

Normal operation
Normal mode: In this condition, the UPS mains input supply is within normal limits, the rectifier and inverter operate
normally, the load is supplied by the inverter, the battery circuit breaker is closed, and the battery is in the stable
floating charge state.
(Parallel System) Note: As the individual UPS module outputs are connected in parallel, the system checks that the
inverter control circuits are perfectly synchronized with one another and with the bypass in terms of both frequency
and phase, and that the output voltages are the same. The current supplied to the load is automatically divided
among the UPS units. A warning message appears while synchronization is in progress.
Mains abnormal
When the mains fails or is abnormal, the rectifier will stop working automatically, and the system will transfer to
battery output (through the inverter). The length of the operation time in battery mode depends on the load and the
battery capacity. During this period, if the battery voltage falls to the EOD level before the mains supply has
returned within normal limits, the inverter will stop working automatically, and the UPS operator control and display
panel will display the corresponding alarm messages. If the system uses split bypass configuration and the bypass is
normal, the system will transfer to bypass.
Mains recovery
When the mains returns within normal limits within the permissible time, the rectifier will start automatically (at this
point its output power will increase gradually) and supply the load and charge the battery again. This means that
the power supply to the load will not be interrupted.
Disconnecting the battery
To disconnect the external battery from the UPS system during maintenance, use the external isolation device. In
this condition, the battery backup function will not be available in the event of a mains failure, but none of the other
UPS functions and performance will be affected.
UPS module failure
In the event of an inverter failure, automatic inverter switch failure, or if the output fuse blows, the load will
automatically transfer to the bypass, and the output power supply will not be interrupted. Should this condition
occur, please contact your local VERTIV customer service centre for technical support.
(Parallel System) In the event of a fault on a UPS module, it will automatically exit the parallel system. If the system
is still capable of providing the power required by the load, the remaining modules will continue to supply the load
without interruptions. If the remaining modules are no longer capable of fulfilling the power requirements, the load
will automatically transfer to the bypass.
Overload
If the inverter is overloaded or the inverter current remains outside the specifications (refer to Table 10-6) longer
than the specified time, the load will automatically transfer to the bypass without any interruption in the power
supply to the load. If both the overload and the current are reduced to a level within the specified range, then the
load will be re-transferred to the inverter. In the event of an output short circuit, the load will be transferred to the
bypass, and the inverter will shut down. The transfer is determined primarily by the characteristics of the system
protection device.
In both the situations listed above, the UPS operator control and display panel will display the corresponding alarm
messages.
(Parallel System) The control logic system constantly monitors load requirements and controls the power supplied
by each UPS module. If an overload condition persists for longer than a pre-set period and the number of active
modules is unable to satisfy load requirements, the load will transfer to the bypass. The load is re-transferred to the
inverter if the power is reduced to a value that can be sustained by the number of active modules in the system.

11
 S600D
Maintenance bypass
The UPS is equipped with a second bypass circuit, known as the maintenance bypass, which provides a safe
working environment for the engineers to carry out regular maintenance or repair the UPS system, while providing
unregulated mains supply to the loads. The maintenance bypass can be activated manually selected by closing the
maintenance bypass switch, and disconnected by setting the switch to OFF.

If the UPS system consists of two or more UPS modules, and the load capacity exceeds the single module capacity, do not
use the internal maintenance bypass switch.

UPS Power Supply Switch Configuration

Figure 1-2 illustrates the block diagram of the UPS module. The UPS may be connected in split bypass (where the
bypass is supplied by a separate mains input source) or common input configuration. In the split bypass
configuration, the static bypass and maintenance bypass share the same independent bypass power supply. Where
a separate power source is not available, the input supply connections of the bypass input switch (Q2) and rectifier
input switch (Q1) should be linked together (these terminals are linked before delivery) so that the bypass input and
rectifier input use mains power from the same source.
During the normal UPS operation, all switches should be closed, with the exception of the maintenance bypass
switch Q3.

Figure 1-2 UPS power supply switch configuration

Battery Circuit Breaker (BCB)

The external battery shall be connected to the UPS via the BCB. The BCB box is an option that must be installed
close to the battery.

1.3 Parallel System

Up to four UPS modules may be parallel-connected to form a parallel system and increase the system capacity and
reliability. The load is shared equally between the parallel connected UPS modules.
Also, two UPS modules or parallel system may be used to form a dual bus system (LBS). Each UPS module or
parallel system has an independent output. Output synchronization is achieved through the LBS cable, thus
enabling seamless load transfer between the two systems.

12
 S600D
Parallel System Features

1. The hardware and software of a parallel system are identical to those of the individual modules. The parallel
system is configured by modifying the respective settings in the configuration software or via the control panel.
2. Parallel cables are connected in a ring, providing both system reliability and redundancy. LBS cables are
connected between any two UPS modules of each bus. The intelligent parallel logic provides the user with maximum
flexibility. For example, the UPS modules in a parallel system can be shut down or started up in any order. Transfers
between normal mode and bypass mode of operation are seamless and self-recoverable, i.e, when the overload is
cleared the system will revert automatically to its original operating mode.
3. The total load of the parallel system can be queried from the LCD screen on each UPS module.

Parallel System Requirements

A group of paralleled modules behave as if it were one large UPS with the advantage of providing increased
reliability. To ensure that all modules are utilised equally and to comply with relevant wiring rules, the following
requirements apply:
1. All UPS modules must be of the same rating and must be connected to the same bypass source.
2. The bypass and rectifier input sources must be connected to the same neutral line input terminal.
3. If any RCD devices are installed they must be set-up appropriately and located upstream of the common neutral
line input terminal. Alternatively, the device must monitor the protective earth current of the system. Refer to
Warning: high earth leakage current before Contents.

1.4 Operating Modes

Operating Principle
The operating principle of the UPS is shown in the figure 1-4.

Figure 1.4 (3X1 UPS with Output Transformer)

1.The UPS is composed of mains input (main and bypass), rectifier/PFC, charger, inverter, bypass, battery, DSP controller,
isolation transformer, contactor and final output.

2. When the mains is normal, the rectifier will start, and the charger will charge the battery string. Before turning on the UPS, the
output voltage is bypass voltage, and the mains supplies power to the load through the bypass. After turning on the UPS, the
electronic transfer switch connects the inverter output to the load, and the mains supplies DC power to the inverter through the
rectifier/PFC circuit. The inverter then converts DC power into pure sine wave AC power and supplies the AC power to the load
through electronic transfer switch. Isolation Transformer is connected at the output side for 3X1,Refer figure 1.4 for the position
of Output Isolation Transformer. Output is fed to Load through Contactor because of Transformer at Output side.

13
 S600D
The UPS features the following operating modes:
⚫ Normal mode
⚫ Battery mode
⚫ Bypass mode
⚫ Maintenance mode
⚫ ECO mode
⚫ Parallel redundancy mode (system expansion)
⚫ LBS system mode
⚫ Common battery string mode
Normal mode
As shown in Figure 1-3, the mains is rectified by the UPS rectifier and then inverted by the inverter to supply
uninterrupted AC power to the loads. At the same time, the charger will charge the battery.

Battery mode
As shown in Figure 1-4, the operating mode where the battery provides the backup power supply to the loads
through the rectifier and inverter is called battery mode. In the event of a mains failure, the system will transfer
automatically to battery mode with no interruption in the power supply to the load. When the mains power supply is
restored, the system will re-transfer automatically to normal operating mode without any manual intervention, and
with no interruption in the power supply to the load.

The battery cold start function may be used to switch the UPS on in Battery (charged) mode directly during mains failure.
This means that the battery power supply can be used independently to improve the availability of the UPS.
Bypass mode
As shown in Figure 1-5, in normal mode, in the event of an inverter failure, inverter overload or inverter manual shut
down, the static switch will transfer the load from the inverter side to bypass side, with no interruption in the power
supply to the load. In this case, if the inverter and bypass are not synchronized, there will be a transitory interruption
in the power supply to the load (not exceeding 20ms).

Maintenance mode

As shown in Figure 1-6, if it is necessary to service the UPS or carry out maintenance work on it, you may use the
manual maintenance bypass switch to transfer the load to maintenance bypass, with no interruption in the power
supply to the load. This maintenance bypass switch is fitted in all UPS modules and rated for full load of one module.

Figure 1-6 Maintenance operating mode line diagram

ECO mode

If ECO mode is selected, all the power switches and the BCB are closed, and the system selects the bypass as the
preferred source of power for the load, in order to save energy. When the bypass supply frequency and voltage are
within normal limits (adjustable), the load is powered by the bypass, with the inverter on stand-by; when the bypass
voltage and/or frequency is outside these pre-defined and adjustable limits, the system will transfer to the inverter
output. In this mode, the system can charge the battery normally.

The load is not protected against distortion on the mains voltage waveform in ECO mode.

Parallel redundancy mode (system expansion)

For higher capacity or higher reliability, or both, the outputs of multiple UPS modules can be programmed for
directly paralleling while a built-in parallel controller in each UPS module ensures automatic load sharing. The
parallel system may consist of up to four UPS modules. For the operating principle diagram of parallel redundancy
mode, see Figure 7-1.
LBS mode
A dual bus system consists of two independent UPS systems, each containing one or more parallel UPS modules.
The dual bus system provides high reliability, which makes it suitable for use with loads having multiple input
terminals. In the case of single-input loads, an STS may be installed to power the load. For the operating principle
diagram of LBS mode, see Figure 7-4.
Common battery string mode
In this mode, when the UPS modules (up to four UPS units) are connected in parallel, they share the same battery
string thus providing cost and space savings.

Never use batteries having different brands, type or capacities in the same system. Common battery string mode is suitable
for parallel systems only, and is not compatible with LBS mode.

1.5 Battery Management

The following battery management functions are set by the service engineer using the VERTIV setting software.

Normal Function

1. Constant current boost charge

Uses a constant current (within battery charging limit) to charge the battery. This function can be used for fast
battery capacity recovery. It is possible to modify the value of the charge current.
2. Constant voltage boost charge
Uses a constant voltage to charge the battery. This function can be used for fast battery capacity recovery. In the
case of VRLA batteries, the maximum boost charge voltage should not exceed 2.4V/cell.
3. Float charge

16
 S600D
This charging method is used for maintaining the battery at full capacity. The float charge voltage is generally low.
This function can be used to compensate for capacity loss due to battery self-discharging, and to recover battery
capacity.
In the case of VRLA batteries, the float charge voltage should be between 2.2V/cell and 2.3V/cell.
4. Automatic transfer to float charge
When the charge current is less than the 'Threshold of Equalize Charge to Float Charge’ value, the charger will
automatically transfer from boost charge to float charge. When the boost charge time exceeds the 'Equalize Charge
Protect Time Limit', the charger will be forcibly transferred to float charge in order to protect the battery.
5. Float charge temperature compensation (optional)
This function must be used together with the battery temperature detection device. The VERTIV battery
temperature sensor is a standard option designed to satisfy your requirements.
6. EOD protection
When the battery voltage falls to the EOD level, the the battery converter shuts down automatically and the battery
is disconnected in order to avoid further battery discharge. The EOD voltage may be set to between 1.6V/cell and
1.85V/cell (VRLA).
7. Battery low pre-warning time
The battery low pre-warning time may be set to between 2min and 30min. The default setting is 2min.
8. Maximum battery discharge time
When the battery is discharged at low current levels for extended periods, it will result in excessive discharge and
may even cause irreparable damage, for this reason it is essential to set-up a maximum battery discharge time in
order to protect it. This limit value is set-up by the service engineer using the VERTIV setting software.
9. Maximum boost charge protection time
To protect against the battery overcharge damage caused by long time boost charge, it is essential to set-up a
protection time a protect time limit This limit value is set-up by the service engineer using the VERTIV setting
software.

Battery Temperature Compensation

The UPS system also features a battery charge temperature compensation function. When the ambient temperature
is increased, the DC bus voltage (which charges the battery) will be reduced correspondingly to provide optimal
charging voltage for the battery, thus prolonging the battery service life time. This function must be used together
with the VERTIV battery temperature detection device (standard option).

1.6 Battery Protection

The following battery protection functions are set by the service engineer using the VERTIV setting software.
Battery low pre-warning
The battery low pre-warning occurs before the EOD. The time can be set to between 2min and 30min.
EOD protection
When the battery voltage falls to the EOD level, the battery converter shuts down automatically. The EOD voltage
may be set to between 1.6V/cell and 1.85V/cell (VRLA).

Chapter 2 Mechanical Installation

This section provides a brief introduction to the UPS mechanical installation procedures, including the precautions,
initial inspection before installation, environmental requirement, mechanical requirement and installation diagram.

2.1 Precautions
This section describes the environmental and mechanical requirements and mechanical considerations that must be
taken into account when planning the positioning and cabling of the UPS equipment.
Because no two sites are the same, this section does not provide the detailed installation procedures, and is only
intended to act as a guide for the general procedures and practices that should be carried out by the installing
engineer, so that they can handle the specific situation at the site correctly.

Warning: professional installation required

1. Do not dismantle the packaging without the permission of an authorised service engineer.
2. The UPS should be installed by an authorised engineer in accordance with the information provided in this section.

Warning: battery danger

Take special care when installing batteries. When connecting batteries, the battery terminal voltage will reach 320Vdc,
which is fatal to human beings.
1. Always wear safety glasses to protect the eyes from being damaged by arcing.
2. Remove all the metal items, including finger rings, watch, etc.
3. Use tools with insulated handles.
4. Wear rubber gloves.
5. If batteries are damaged or leak electrolyte they must be replaced. Place the battery into the container that can withstand
sulphuric acid and dispose of it according to the local regulations.
6. In the event of contact with electrolyte, wash the affected are with abundant clean water immediately.

2.2 Transportation
Rail and sea shipping are the recommended transportation methods. If road transportation is unavoidable, choose
roads that are less bumpy in order to protect the equipment.
The UPS cabinet is heavy (see Table 10-3 for the weight). We recommend using mechanical equipment such as an
electric forklift to unload and move the equipment to the place closest to the installation site.

18

2.5 Initial Inspection

Before installing the UPS, carry out the following inspections:
1. Ensure that the UPS equipment room meets the environmental requirements specified in the product technical
specifications, especially the ambient temperature, ventilation conditions, and the levels of dust.
2. Unpack the UPS and battery under the supervision of an authorized service engineer. Visually inspect the inside
and outside of the UPS and battery for any shipping damage. If there is any damage, report it to the carrier
immediately.
3. Verify the UPS label and confirm that the UPS model conforms to the information indicated on it. The UPS label is
attached to the rear of the door. The UPS model, capacity and the main parameters are marked on the label.

2.6 Environmental Requirements

Selecting the UPS Location

The UPS should be located in a cool, dry, clean-air indoor environment with adequate ventilation, and should be
located on concrete or other non-flammable, flat surfaces. The surrounding environment should be free from
conductive powders (such as metallic powder, sulphide, sulphur dioxide, graphite, carbon fibre, conductive fibre,
etc.), acid mist or other conductive media (strongly ionized substances). The environmental specifications should
comply with relevant international standard & specifications and the operating range (see Table 10-2) specified in
this manual.
The UPS uses forced cooling by internal fans. Cooling air enters the UPS through the ventilation grills at the front of
the cabinet and is expelled through the ventilation grills at the back of the cabinet. Do not obstruct the ventilation
holes (ventilation grills). The rear of the UPS should be kept a distance at least 200mm from the wall to avoid
blocking the UPS heat dissipation, thus reducing the UPS internal temperature and improving the UPS life.
If necessary, install indoor extractor fans to aid cooling-air flow and avoid temperature build-up in the installation
area.

Note 1: When the battery cabinet is installed near the UPS, the maximum allowable ambient temperature is dependent on
the battery rather than the UPS.
Note 2: If the UPS is operating in ECO mode, the power consumption will be less than in Normal mode. A proper air
conditioning system shall be selected according to the normal operating mode.

Selection the Battery Location

Batteries generate a certain amount of hydrogen and oxygen at the end of the charging cycle, so the fresh air
volume of the battery installation environment must meet the EN50272-2001 requirements.
The ambient temperature is the main factor that affects the battery capacity and life. The normal operating
temperature of the battery is 20°C. If the ambient temperature is higher than 20°C, the battery life will be reduced. If
it is lower than 20°C, the battery capacity will be reduced. Under normal operating conditions, the acceptable
ambient temperature for the battery is 15°C to 25°C. The ambient temperature of the battery must be maintained
constant, and the battery must be kept away from heat sources and air outlets.
The battery may be installed inside the dedicated battery cabinet, which shall be positioned close to the UPS. If the
battery is placed on the raised floor, brackets shall be installed under the floor, just as for the UPS. In the case of
rack-mounted batteries or batteries that are installed remotely from the UPS, the battery circuit breaker shall be
installed close to the battery, and the cable lengths shall be kept to a minimum.

Storage

Should the UPS not be installed immediately, it must be stored in its original packaging in a location where it is
protected against excessive humidity and heat sources (see Table 10-2). The battery must be stored in a dry and
cool place with good ventilation. The most suitable storage temperature is between 20°C and 25°C.

23
 S600D

Recharge the battery at regular intervals during storage in accordance with the manufacturer’s instructions. During the
charge process, connect the UPS temporarily to the mains and activate the battery by recharging it.

2.7 Mechanical Requirements

Moving the Cabinet

1. Ensure that the load capacity of the lifting equipment used to move the UPS cabinet is sufficient.
2. The UPS is fitted with castors. When removing the UPS from the shipping pallet, take care to prevent it from sliding.
Ensure that sufficient personnel and lifting equipment are available when removing the shipping pallet.
3. Due to the weight of the UPS cabinet, the castors may only be suitable for use on flat surfaces.
4. The centre of gravity of the UPS cabinet is high, take care to prevent it tipping over when moving it
5. The cabinet must never be suspended vertically.

Take special care when moving the battery cabinet with the batteries installed, making sure that each battery string has
been secured and keeping movements to a minimum.

Ensure that the UPS weight does not exceed the load capacity of the lifting equipment. For information about the
weight of the UPS, refer to Table 10-3.
The UPS may be moved using a forklift truck or similar lifting equipment.
The castors may be used when it is necessary to move it over short distances.

Clearance

Because the UPS is not fitted with lateral grilles, there is no special clearance requirement on either side.
In addition to any local regulations, in order provide sufficient space for routine operations, such as tightening the
power terminals inside the UPS, it is recommended that clearance around the front of the UPS should be sufficient
to enable free passage of personnel with the door fully open. In addition, it is necessary to leave a clearance of at
least 200 mm at the rear of the cabinet in order to permit adequate circulation of the hot air expelled by the UPS.

Cable Access Mode

UPS cable access is from the rear bottom side of

the cabinet. For details, refer to 3.1.10 and 3.2.8 .

Chapter 3 Electrical Installation

This section principally introduces the UPS electrical installation procedures, including the power cable and signal
cable connecting procedures and methods.
Once the mechanical installation procedure is complete, it is necessary to connect the power and signal cables to
the UPS. All signal cables, whether or not they are shielded, must be kept away from the power cables.

1. Do not switch the UPS on before the authorised service engineer arrives.
2. The UPS should be routed by an authorised engineer in accordance with the information provided in this section.

3.1 Connecting the Power Cables

System Configuration

The system power cable dimensions shall meet the following requirements:
UPS input cable
The UPS input cable dimension differs depending on the UPS power ratings and input AC voltages, provided that it
meets the requirement of maximum input current, including the maximum battery charge current, see Table 3-1.
UPS bypass and output cable
The UPS bypass and output cable size differs depending on the UPS power rating and output AC voltages, provided
that it meets the requirement of nominal output or bypass current, as shown in Table 3-1.
Battery cable
Each UPS is connected to the respective battery positive pole, negative pole and neutral line by three cables . The
battery cable dimension differs depending on the UPS power ratings, provided that it meets the battery discharge
current requirement when the battery voltage nears the EOD level, as shown in Table 3-1.

Maximum Steady State AC and DC Currents

The power cable must be selected according to the current and voltage values indicated in Table 3-1, as well as the
local wiring regulations, as well as taking environmental conditions (temperature and physical media) into
consideration; refer to Table 3B in IEC 60950-1.

When selecting the battery cables, a max. volt drop of 4Vdc is permissible at the current ratings given in Table 3-1. Avoid coiling
the cables as this would increase the electromagnetic interference (EMI).
1. Input mains current for rectifier and bypass.

26
 S600D
2. Non-linear load (like switch power) affects the design of output and bypass neutral line. The neutral line current may exceed
the rated phase current, at most 1.5 times of the rated phase current.

Recommended CSA of UPS Cables and corresponding Lugs

The recommended CSA of the UPS cables is listed in Table 3-2.

Table 3-2 Recommended CSA of the UPS cable (unit: mm2, ambient temperature: 25°C)

20 (3-in 1-out ) 10 10 10 10 10 10

When the system is in common input configuration and in 3-in 1-out mode, because phase A powers the load, the input cable of
phase A must be selected according to Table 3-2. Input cables of phase B and phase C may refer to Table 3-2.
Lugs for Input, Output, Common / Split Bypass, Battery connections MUST be of Ring type cross-section, suited for Cables and
Currents in use.

Selecting the UPS I/O Switch

Notes

The following points are provided for general guidance only. If there are corresponding local regulations, such
regulations shall prevail.

27
 S600D
1. The protective earth cable dimension shall be selected according to the AC power failure level, cable length and
protection type. The grounding wire connection must use the shortest possible connection route.
2. In the case of cables that are required to handle large current, it may be easier to use multiple smaller cables in
parallel.
3. When selecting the battery cable dimension, it is important to take the current value in Table 3-1 into account and
bear in mind that the maximum permissible voltage drop is 4 Vdc.
4. Avoid coiling the cables as this would increase the electromagnetic interference (EMI).

Power Cable Connecting Terminal

The rectifier input, bypass input, output and battery power cables are connected to the corresponding terminals, as
shown in Figure 3-2.

Protective Earth

The protective earth cable must be connected securely to the PE input terminal (see Figure 3-2) using the fastening
bolt. All the cabinets and cable troughs shall be earthed according to the local regulations. The earthing wires shall
be secured in order to prevent them coming loose from the fastening screws if they are pulled.

Failure to earth the various elements as directed may result in EMI, electric shock or fire risk.

External Protective Device

To ensure safety, it is necessary to install external circuit breakers on the UPS input and battery lines. Because no
two installations are the same, this section is only intended to provide general practical guidelines for installation
engineers. Qualified installation engineers should be aware of the local wiring regulations and any other related
information
Rectifier and bypass input power supply
1. Input overcurrent and short circuit protection
Install suitable protective devices on the mains input supply distribution line. The protective devices should provide
functions such as overcurrent protection, short circuit protection, isolation protection and tripping upon backfeed.
When selecting the protective devices, consider the power cable current-carrying capacity, system overload
capacity (see Table 10-6 and Table 10-7) and the short circuit capacity of the upstream power distribution.
2. Split bypass configuration
If the UPS adopts the split bypass configuration, independent protective device shall be installed on both the
rectifier input and bypass input distribution lines.

1. The rectifier input and bypass input must use the same neutral line.
2. In the case of IT grid systems, a 4-pole protective device must be installed on the UPS external power distribution line.

3. Earth fault protection

If the upstream input power supply his fitted with an RCD, it is important to take the transient state and steady state
earth leakage current upon the start-up of the UPS into account.
The RCCB shall meet the following requirements:
⚫ Be sensitive to DC unidirectional pulses (class A) in the power distribution network
⚫ Be immune to transient current pulses
⚫ Have an average sensitivity of 0.3A - 3A (adjustable)
The RCCB symbols are shown in Figure 3-1.

28
 S600D

Figure 3-1 RCCB symbols

The UPS is fitted with an internal EMC filter, therefore the protective earth cable leakage current is 0 - 1000mA. We
recommend confirming the RCD sensitivity of the upstream input power distribution and downstream power
distribution (to the load) lines.
External battery
The BCB must be installed in order to protect external battery. The UPS requires an optional BCB box to provide
overcurrent protection, short circuit protection and automatic tripping functions for the external battery. The rated
voltage of the BCB is 500Vdc.
This BCB is extremely important for the battery maintenance, and is generally installed close to the battery.
System output
The UPS output distribution line must be fitted with a protective device. The protective device must be different
from the input distribution protection switch and be able to provide overload protection (refer to Table 10-6 and
Table 10-7).

Power Cable Connection Steps

For the UPS cable access mode, refer to 2.7.3 .

Connection terminals and cable routing method
Figure 3-2 shows the UPS power cable connection terminals. Figure 3-3 shows the power cable entry and routing
methods.

1. Open the appropriate holes on the rear protective cover before routing the power cables. Install cable guards around the
rims of the hole to protect power cables against cutting.
2. Feed the power cables through the holes, then connect them to the corresponding terminals.

Figure 3-2 Power cable connection terminals (rear view)

29
 S600D

Remove this Panel,open holes

and lead cables through holes to
corresponding terminals

Figure 3-3 Power cables wiring diagram (rear cable access)

1. Before connecting the cables, make sure that all the external and internal UPS power switches are set to OFF, and post the
appropriate warning signs to prevent inadvertent operation of the switches.
2. Measure the voltages between the UPS terminals, and the voltages between the terminals and earth.

1. The earth cables and neutral line must be connected in accordance with local and national codes of practice.
2. Failure to observe this condition may result in electric shock or fire risk.

Power distribution mode

Based on the user's requirements, it is possible to select one of the following I/O cable connection configurations:
⚫ 3-in 1-out, common input configuration
⚫ 3-in 1-out, split bypass configuration
Connecting the system input
1. 3-in 1-out, common input configuration (factory default)
Refer to Figure 3-4, connect the AC input cables to the three copper shorting bars between the rectifier input
terminals (mA-mB-mC) and the bypass input terminals (bA-bB-bC) in the cabinet. Connect the input neutral line to
the terminal N in the cabinet. Make sure that the phase rotation is correct.

30
 S600D

Note

Note that the common input copper shorting bars are fitted before delivery.

Figure 3-4 3-in 1-out, common input configuration cable connection (factory default)

2. 3-in 1-out, split bypass configuration

Refer to Figure 3-5, remove the three copper shorting bars between the rectifier input terminals (mA-mB-mC) and
the bypass input terminals (bA-bB-bC). Connect the rectifier input cables to the rectifier input terminals (mA-mB-
mC) in the cabinet, and connect the bypass input cables to the bypass input terminals (bA-bB-bC) in the cabinet.
Connect the input neutral line to the terminal N in the cabinet. Make sure that the phase rotation is correct.

3. 3-in 1-out, common input configuration

For more details, refer to 8.2.7 .
4. 3-in 1-out, split bypass configuration
For more details, refer to 8.2.7 .
Connecting the system output
In the case of 3-in 1-out configurations, connect the system output cables between the output terminals (oA-oB-oC-
oN) and the load; whereas, in the case of 3-in 1-out configurations, connect the system output cables between the

31
 S600D
output copper shorting bars (oA-oB-oC), oN and the load. Refer to Table 3-1 for the tightening torque values. Make
sure that the phase rotation is correct.

Prior to the service engineer's visit, if the load is not ready to be connected to the power supply, it is important to ensure the
terminals of the output cables are insulated safely

Connecting the batteries

If the external battery is required, ensure correct polarity between the battery string terminals and the BCB, and
between the BCB and the UPS cabinet battery input terminals (Bat+, N, Bat-), i.e. (Bat+) to (+), (Bat-) to (-) and (N)
to (N).
This completes the connection procedure. At this point it is possible to replace the protective covers.

After connection, take appropriate measures to seal the cable entry holes.

3.2 Wiring the Signal Cables

Overview

Depending on the specific on-site needs, the UPS requires auxiliary connections to manage the battery system
(including the external battery circuit breaker), communicate with a PC, provide alarm signals for external devices,
enable a remote EPO and/or the bypass back feed circuit breaker signal, and for parallel communication functions.
These functions are performed by the communication box in the UPS cabinet. As shown in Figure 3-6, the
communication box provides the following ports:

1. Intellislot port
2. Dry contact port
3. RS232 port
4. Ethernet port (not used)
5. Parallel/LBS port
6. REPO port
7. USB port
8. Multifunctional port

Dry Contact Port

The UPS provides five dry contact ports. The silkprints of the five dry contact ports are 1 - 12. The pin layout of each
dry contact port is shown in Figure 3-7, and the port description is shown in Table 3-5.

The terminals corresponding to Pin 11 and Pin 12 are reserved for configuring the REPO function. The REPO device
also requires a shielded cable for connecting the Normally Open remote REPO switch between the two terminals. If
not required, you should disconnect Pin 9 and Pin 10. Pin 9 and Pin 10 have been shorted together before delivery.

Note

33
 S600D
Activating the UPS EPO will deactivate the rectifier, inverter and static bypass, but does not disconnect the UPS from the
mains input. If you wish to disconnect the UPS completely, it is also necessary to open the input MCB installed upstream of
the UPS when activating the EPO.

In the event of an emergency, close the REPO switch (supplied and installed by the user) in order to shut down the
rectifier and inverter, and switch the UPS off. Under normal conditions, the REPO switch cannot be used to isolate
the UPS from the mains input power. If an electronically controlled circuit breaker function is installed at the UPS
input, the REPO switch can be used to trip this breaker, thus cutting off the UPS mains input power. The position of
the REPO switch is shown in Figure 3-6, and the REPO cable connection is shown in Figure 3-8.

Figure 3-8 Connecting the REPO cable

The cable connection procedures are as follows:

1. Release the REPO port connection terminals '11' and '12'.
2. Strip the insulation from the ends of the two copper core cables and insert them in the REPO port connection
terminals '11' and '12', and press the terminals down in order to secure the cables. The REPO cable connection
procedure is complete. Ensure that the REPO cable is connected securely in order to ensure that the REPO is not
activated inadvertently as the result of poor contacts.
3. In the case of parallel UPS systems, when connecting the REPO cable, users should connect terminal '11' of the
REPO port in parallel to one terminal of each electronic switch, and terminal '12' of the REPO port in parallel to the
other terminal of each electronic switch.
When the REPO switch at the user end is closed, the UPS will generate an alarm and cut off the output immediately,
and the UPS will not return to the normal operating state automatically. At this point, it is necessary to change the
REPO switch state, and switch the UPS on manually.

1. We recommend using 0.82mm2 - 0.33mm2 copper core cable ( 18AWG - 33AWG signal cable).
2. If the REPO has been configured to trip an electronically controlled circuit breaker switch, after the REPO has been
activated it will be necessary to re-arm the switch before restarting the UPS.

RS232 Communication Port

To connect the serial port communication cables, proceed as follows:

Insert one end of the DB9 serial port communication cable into the DB9 serial port (see port 3 in Figure 3-6) on the
rear panel of the UPS, and connect the other end to the DB9 port on the computer.
The pin functions of the DB9 port are listed below:

34
 S600D
After connecting the cable, it is necessary to install the USB drive program on the installation disk.

Parallel/LBS Communication Port

The position of this port is shown in Figure 3-6.

Intellislot Port

The position of this port is shown in Figure 3-6. The Intellislot port is used for installing optional cards, including the
SIC card, UNITY card, etc. The Intellislot port can be used together with other ports.

Multifunction port

The multifunction port uses the standard RJ45 port, which supports the Modbus/Jbus protocol and can be used to
connect the VERTIV temperature & humidity sensor. The user can enable Modbus/Jbus protocol function or sensor
function via the 'Settings' on the LCD.

Signal Cable Connection Steps

Route the power and signal cables respectively. The signal cable shielding sheath must be earthed securely.

Rear cable access mode is available. See Figure 3-10 for a detailed description of the wiring method.

Chapter 5 Operating Procedures

This section introduces the operating precautions and describes the UPS operating procedures in detail.

5.1 Brief Introduction

Precautions

The user may only carry out the operations described in this section once the authorised service engineer has switched the
UPS on for the first time and completed the commissioning tests

Warning: hazardous mains and/or battery voltage

1. No user serviceable parts are located behind the protective covers that can only be removed by using tools. Only qualified
service personnel are authorized to remove such covers.
2. Hazardous voltages may be present on the UPS AC input and output terminals at any time. If the cabinet is equipped with an
EMC filter, hazardous voltages may be present on the filter.

1. For information about the control keys and LCD related to all the operating steps, refer to Chapter 4 .

2. During operation, the buzzer alarm may be activated at any time. Press the key for 3s to silence the audible
alarm.
3. When the UPS is equipped with traditional lead-acid batteries, the system provides the optional boost charge
function. If lead-acid batteries are used, when the mains returns after an extended mains failure, the battery
charging voltage will be higher than the normal charging voltage, this is normal, and the charging voltage will return
to its normal value after a few hours.

Power Switch

Open the front door of the UPS cabinet to access the power switches, as listed below, (see Figure 5-1):
Q1: Rectifier input switch - connects the UPS to the main power supply.
Q2: Bypass input switch - connects the UPS to the bypass power supply.
Q3: Maintenance bypass switch(lockable) - supplies power to the load when UPS is being serviced.

If the UPS system consists of more than 2 UPS modules in parallel, do not use the internal maintenance bypass switch

Q5: Output switch - connects the UPS output to the load.

Transfer From Normal Mode To Maintenance Bypass Mode

When the UPS is running in Normal mode, you can use this procedure to transfer the load from inverter output to
maintenance bypass.

Before performing this procedure, you should check the LCD information first, and make sure the bypass is normal and
synchronized with the inverter. Failure to do so may result in a brief interruption in the power supply to the load.

1. Remove the maintenance bypass switch baffle retaining screws, rotate the baffle upwards until it is locked in
position, and then fasten the retaining screws. As shown in Figure 5-13.

Figure 5-13 Moving the baffle upwards

At this point, the system Interlock function has been activated and the UPS will transfer to internal bypass mode;
you should confirm that the UPS has been transferred to internal bypass mode.
2. After confirming, close the maintenance bypass switch Q3.
3. Disconnect the output switch Q4.

When the UPS is in maintenance bypass mode, the load is not protected against abnormalities in the mains power supply.

4. Unplugging the REPO terminal deactivates the rectifier, inverter, static switch and battery, but does not affect the
maintenance bypass power supply to the load.

In maintenance mode, the load is fed directly by the mains power instead, of the pure AC power from the inverter.

5. Disconnect the rectifier input switch Q1 and bypass input switch Q2. At this point, all the internal power supplies
are deactivated and the LCD screen is switched off.
6. If the UPS is equipped with internal batteries, make sure that that they have been isolated from the UPS before
carrying out maintenance work on it. Refer to 6.10 for details.

Transfer From Maintenance Bypass Mode To Normal Mode

Following UPS maintenance operations, the following procedures may be used to transfer the load from the
maintenance bypass to the inverter.
1. If the UPS is equipped with internal batteries, simply connect the UPS and internal batteries when you finish
servicing the UPS. Refer to 6.10 for details.
2. Close the output switch Q4.
3. Close the bypass input switch Q2.
4. Following the LCD start-up, ensure that the system is operating in Bypass mode.

Warning

58
 S600D

It is important to close the bypass switch (Q2) before opening the maintenance bypass switch; otherwise the power supply to
the load will be interrupted.

5. Set internal maintenance bypass switch Q3 to off. Return the Q3 baffle to its original position, then fasten the
retaining screws.
6. Close the rectifier input switch Q1, wait for the rectifier to start-up.
7. Press the power button on the operator and display panel of the UP so that the UPS transfers to Inverter mode.
At this point, the load has transferred to UPS normal mode.

5.4 UPS Shut-down Procedures

Procedures For Completely Powering Down the UPS

In order to shut the UPS down completely and disconnect the power supply to the load, proceed as follows: All
power switches, isolating switches and breakers are switched to off, and the UPS no longer supplies power to the
load.

The following procedures will interrupt the power supply to the load, switching it off.

1. Press the power button on the display panel, the UPS will transfer to Bypass mode.
2. Unplug the REPO terminal at rear of the UPS to deactivate the rectifier, inverter, static switch and battery.
3. If the UPS is equipped with an external battery, set the corresponding external battery switch to off.
4. Set the rectifier input switch Q1 and bypass input switch Q5 to off. At this point, all the internal power supplies are
deactivated and the LCD screen is switched off.

1. Post a label on the AC input distribution line (generally at a distance from the UPS) to alert personnel that UPS
maintenance is in progress.
2. Wait 10 minutes for the internal DC bus capacitors to discharge. Then the UPS is completely shut down.

Warning: hazardous battery voltage

Hazardous voltages are still present on the battery terminals, even after the UPS has been shut down.

Neutral not disconnected. Parts of the equipment might remain energized, representing a hazard during servicing.

Procedures Shutting Down the UPS Completely While Maintaining Power To Load

The following procedures may be used to shut the UPS down completely are applicable for completely, while
maintaining the power supply to the load. Refer to the procedures in 5.3.4 .

5.5 REPO
The REPO port, located at rear of the UPS, is designed to switch off the UPS in the event of an emergency (such as
fire, flood). After unplugging the REPO terminal, the system will switch off the rectifier and inverter, and interrupt
the power supply to the load immediately (inverter and bypass output included), while the battery will stop charging
or discharging.

59
 S600D

After EPO, if the mains input is present, the UPS control circuit will remain active; however, the output is interrupted.
To completely remove all mains power from the UPS, first disconnect the UPS external mains switches, and then
disconnect the battery terminals.

5.6 Automatic Restart

In the event of a mains power failure, the UPS draws power from the battery in order to supply the load until the
batteries are discharged, at which point the UPS will shut down.
The UPS will restart automatically and resume supplying power to the load:
⚫ Once the mains power supply is restored.
⚫ If the UPS Auto Restart function is enabled.
⚫ After the Auto Restart delay has expired (default: 10s). During the Auto Restart delay, the UPS will charge the
battery in order to provide a safety margin for equipment shut-down if input power fails again.
If the Auto Restart function is disabled, you can restart the UPS manually by pressing the power button.

Chapter 6 Battery
This section introduces the battery, providing information about safety, installation and maintenance, and the
battery protection function.

6.1 Introduction
The UPS battery string consists of a number of batteries connected in series, and provides rated DC input voltage
for the UPS inverter. The required battery backup time (i.e. The length of time the battery is able to supply the load
for following a mains failure) depends on the ampere-hour value of the battery. Under certain conditions, it may be
necessary to connect several battery strings in parallel.
For ease of installation, the battery is generally placed in the specially designed battery rack or a dedicated battery
room.
During the maintenance or repair, the battery must be disconnected from the UPS. This may be achieved by using a
suitably rated battery circuit breaker. This circuit breaker must be located as close as possible to the battery
connection terminals, while the length of the power and signal cables connected to the UPS must be kept to a
minimum.
When several battery strings are connected in parallel in order to increase the battery backup time, each string must
be fitted with its own disconnecting device, so that, when it is necessary to carry out maintenance work on an
individual battery string, the normal operation of the other strings is not affected.

6.2 Safety
Take special care when working with the batteries associated with this UPS. When all the blocks are connected, the
battery string voltage can reach 540Vdc. This is potentially lethal. Please follow the precautions for working with
high voltages.
Only qualified personnel may install and service the battery. To ensure safety, the external batteries must be
installed inside a lockable cabinet or in a purpose-designed, dedicated battery room, so that they are only
accessible to qualified service personnel.
Confirm that the battery switch has been set to off before carrying out battery maintenance operations.

66
 S600D

Warning: hazardous battery voltage present behind covers

1. No user-serviceable parts are located behind the protective covers that can only be removed by using tools. Only qualified service
personnel are authorized to remove such covers.
2. Before working on the copper bars connected to the external battery, please ensure they are disconnected from all power supplies.

Proper connection mode Improper connection mode

Applying too little or too much torque may result in poor connections. Under
Tighten the terminal bolt of the battery,
certain conditions, the terminal may be subject to arcing or heat accumulation,
applying the specified torque
which can result in fire

3. Observe the following safety precautions when working on the batteries:

a) The batteries must be firmly and securely connected. After the connection is completed, the screw connections between all the
terminals and the batteries shall be calibrated. The torque requirements indicated in the specifications or user manual provided by the
battery manufacturer must be respected. The connections between all the wiring terminals and the batteries shall be inspected and
tightened at least once a year. Failure to do so may result in fire!
b) Visually inspect the batteries before accepting and/or using them. If the packaging is damaged, the terminals are dirty, eroded or
rusty, or if the cases are cracked, deformed or leaky, replace the battery with a new one. Failure to do so may result in reduced battery
capacity, leakage of electrolyte or even fires.

Battery damaged during handling or shipping After a week of normal charge/discharge cycle testing

c) Batteries are very heavy. Please use the proper procedures when moving and lifting batteries in order to prevent injury and avoid
damaging battery terminals. Severe damage to the battery may cause fire.
d) The battery connecting terminal must not be subject to any force, such as pulling twisting forces exerted by the cables, otherwise,
the internal battery connections may be damaged. Severe damage to the battery may cause fire.
e) The battery must be installed and stored in a clean, cool and dry environment. Do not install the battery in a sealed battery chamber
or a sealed room. The battery room ventilation shall at least meet the requirement of EN50272-2001. Otherwise, battery bulging, fire or
even human injury may be caused.
f) Batteries must be installed away from heat sources (e.g. Transformers) and kept away from sources of fire, in addition, they must not
be burnt or heated in a fire. Otherwise, battery leakage, bulging, fire or explosion may be caused.
g) Do not connect conductors directly between the positive and negative terminals of the battery. Remove the rings, watches,
necklaces, bracelets and other metal items before working on batteries, and always used insulated tools (e.g. wrenches). Otherwise,
battery burning, human death/injury or explosion may be caused.
h) Do not attempt to disassemble, modify or demolish batteries. Otherwise, battery short circuit, liquid leakage or even human injury

67
 S600D

Warning: hazardous battery voltage present behind covers

may be caused.
i) Clean the battery enclosure with a damp cloth. To avoid any static or arcing, do not use dry cloths or dusters to clean the batteries.
Do not use the organic solvents (such as thinners, gasoline, volatile oil) to clean the batteries. Otherwise, the battery enclosure may be
cracked. In the worst case this may even result in fires.
j) The batteries contain diluted sulphuric acid. In normal use, the diluted sulphuric acid will be absorbed by the battery baffle and polar
plate. However, if the battery is damaged, it may leak acid. Therefore, personal protective equipment (e.g., protective glasses, rubber
gloves and apron) must be used when working with batteries. Failure to observe the above may result in blindness, if the sulphuric acid
comes into contact with the eyes, or burns, if it comes into contact with the skin.
k) batteries may be a affected by short circuits, electrolyte dry-up or positive pole erosion failure at the end of their service life.
Continued use it this state may result in thermal runaway, bulging or liquid leakage. Please replace the batteries before they reach this
state.
l) Before connecting or disconnecting the battery connection cables, please isolate them from the battery charger terminals.
m) Check whether the battery has been unexpectedly earthed. If so, remove the earth connection. Contact with any part of the earthed
battery may result in an electric shock.

6.3 UPS Battery

The UPS is normally equipped with valve-regulated batteries. The term 'valve-regulated' replaces the 'sealed type'
or 'maintenance free', which were used in the past.
Valve-regulated batteries are not completely sealed, therefore some gas will be expelled especially when they are
over-charged. The volume of expelled gas is less than that for water injection type batteries. However, when
designing the battery installation area, it important to take the possibility of temperature rise into account and
ensure there is sufficient space to ensure good ventilation.
Additionally, it is worth noting that valve-regulated batteries are not entirely maintenance free. In fact, they must be
kept clean, and inspected regularly to check if the connection is secure and the terminals are free from corrosion.
For details, please refer to 6.9 .
We recommend that you do not connect more than 4 strings of batteries in parallel. All batteries in the same system
must be of the same type, brand, capacity and age. Failure to observe this condition will result in regular over/under
charging of certain batteries within the string. This will eventually lead to premature failure, compromising the back-
up time of the affected string.
The battery must be stored in fully charged state. The battery will lose a certain proportion of its capacity due to self -
discharge during the shipping or storage. Charge the battery before use. During storage, ensure that the ambient
temperature remains within between -15°C and +45°C; the optimal temperature range is between 20°C and 25°C.
To compensate for the self-discharge, recharge the battery once every 3 months during while it remains in storage.
This period may differ, depending on the specific batteries. For details, refer to the battery manufacturer’s
specifications.
It is important to ensure the battery is fully charged before carrying out the on site battery backup time test. This
test may take several days. Therefore, it should be conducted after the battery has been subject to uninterrupted
float charging for at least one week.
The battery performance will gradually increase after it has been running for several weeks or subject to two to
three charge and discharge cycles.
To avoid over/under-charging the battery, please set-up the battery management parameters according to the
equalizing/float charge voltage and temperature compensation factor specified in the manuals provided by the
battery manufacturer. Please charge the battery immediately after is has been discharged.

68
 S600D

6.4 Precautions For Installation Design

1. The precautions that must be applied when installing, using and servicing the batteries are described in the respective
battery manual provided by the battery manufacturer.
2. The safety precautions described in this section include important matters that must be taken into account when designing
the installation.
3. The design results may vary according to the local situation.

6.5 Battery Installation Environment and Number of Batteries

Installation Environment

Fresh air volume (EN50272-2001)

The battery operating environment must be well ventilated. During battery operation, the following fresh air
ventilation requirement must be satisfied:
Q=0.05 x n x Igas x Crt x 10–3[m3/h]
Where:
Q = The fresh air ventilation volume per hour, the unit is m3/h
N = Number of cells
Igas = The gas evolving current density under battery float charging or boost charge conditions, the unit is mA/Ah
Igas=1, under the float charging condition of 2.27V/cell
Igas=8, under the float charging condition of 2.35V/cell
Crt = 20hr battery rated capacity
Temperature
Table 6-1 Ambient temperature range
Type Temperature value Note
Recommended The ambient temperature for the battery operation must not be too high or
20°C - 25°C
optimal temperature too low.
If the average operating temperature of the battery rises from 25°C to 35°C,
Short time allowable the service life of the battery will be reduced by 50%. If the operating
-15°C - 45°C
temperature temperature of the battery exceeds 40°C, the service life of the battery will
be reduced exponentially each day

The higher the temperature, the shorter the battery service life. At low temperatures, the charge/discharge
performance of the battery will be significantly reduced.
The battery must be installed in a cool and dry environment where the relative humidity is less than 90%, and must
be protected from heat sources and direct sunlight.
The ambient temperature, ventilation, space, float/boost charge voltage and ripple current will all affect the battery
temperature. Uneven temperature among the battery strings will cause uneven voltage distribution and thus
compromise performance. Therefore, it is very important to maintain a balanced temperature along the entire length
of the battery string, and to ensure that the temperature difference between batteries on different layers does not
exceed 3°C. Valve-regulated batteries are very sensitive to the temperature, therefore the working temperature
should be maintained between 15°C and 25°C. If the battery cabinet is installed near the UPS, the maximum design
ambient temperature shall be determined according to the battery rather than the UPS. This means that, if valve-
regulated batteries are used, the indoor ambient temperature shall be 15°C - 25°C rather than the operating
temperature range of the UPS modules. Provided the average temperature remains below 25°C, brief excursions in
excess of this value are permitted.

69
 S600D

Number Of Batteries

The number of batteries, EOD voltage, and float charging voltage must be consistent with the voltage selection
(220V/230V/240V), as shown in Table 6-2.
Table 6-2 Number of batteries
Parameter 220V/230V/240V
Number of cells (standard) 192, 240
EOD voltage 1.60Vdc/Cell - 1.85Vdc/Cell, 1.62V/cell recommended
Float charging voltage 2.2Vdc/Cell - 2.3Vdc/Cell, 2.27V/cell recommended

6.6 Battery Protection

If internal batteries are selected, the UPS is equipped with an internal fused switch designed to protect the internal
battery. If external batteries are selected, please select a BCB with sufficient DC breaking capacity.

To avoid risks, we recommend using a VERTIV BCB for your external battery.

The external battery must be connected to the UPS via the BCB. The BCB can be closed manually and is equipped
with an electronic tripping device controlled by the UPS control circuit. In the case of rack-mounted batteries (or
batteries that are installed at a distance from the UPS cabinet), the BCB must be installed as close to the battery as
possible, and the length of the power and signal cables connected to the UPS must be kept to minimum.
The UPS provides the following advantages:
⚫ Safe, reliable battery isolation
⚫ Short circuit protection
⚫ If the inverter is locked because of battery under-voltage, the circuit breaker will be opened
⚫ automatically in order to avoid over-discharging the battery.
⚫ If the remote EPO button is installed, the EPO button can be used to open the circuit breaker
⚫ Protection against misuse
To obtain the required backup time, the batteries may be connected in parallel. In this case, the BCB must be
installed downstream of the battery parallel connection point.

Only trained personnel may operate and service the battery circuit breaker.

6.7 Battery Installation and Connections

Battery Installation

1. Before installation, check the batteries for damage, inspect and count the accessories, and carefully read this
manual and the user manual or installation instructions provided by the battery manufacturer.
2. There must be a vertical gap of at least 10 mm between the batteries in order to ensure the free circulation of the
ambient air between the batteries.
3. A certain amount of clearance shall be maintained between the top of the batteries and the next layer in order to
facilitate battery monitoring and service operations.
4. Install the batteries starting from the bottom layer and working upwards, in order to avoid creating a high centre
of gravity. The battery shall be properly installed and protected against vibration and/or impacts.

70
 S600D

Battery Connections

1. All the battery cabinets or battery racks must be connected and properly grounded.
2. When multiple battery strings are used, they shall be connected first in series and then in parallel. Before
switching the UPS on and connecting it to the load, check that the total voltage of the batteries is as specified. The
negative and positive poles of the batteries must be connected to the negative and positive battery terminals of the
UPS, in accordance with the labels on the battery and UPS. If the battery connections are inverted it can cause fires
or explosions, and may result in battery and UPS damage or even human injury.
3. When the battery cable connection procedure is complete, install insulating shields on the terminals.
4. When connecting the cable between battery terminal and BCB, the BCB terminal must be connected first.
5. The bending radius of the cable shall be larger than 10D, wherein D is the outer diameter of the cable.
6. When the battery cable is connected, it is prohibited to pull on the battery cable or the cable terminal.
7. Do not cross the battery cables when connecting them, and do not tie the battery cables together.
8. See 8.2.1 Internal Battery Kit for details about the battery connections.

6.8 Designing the Battery Room

Irrespective of the type of installation system that is adopted, it is important to pay particular attention to the
following items (refer to Figure 6-1):
Layout of cells
Irrespective of the type of installation system that is adopted, the batteries must be positioned so that no two parts
having a potential difference of greater than 150 V can come into contact with each other at any time. If this is
unavoidable, insulated terminal shields and insulated cables shall be used for the respective connections.
Workbench
The workbench (or platform) must be skid-proof and insulated, and at least 1m wide.
Wiring
All the wiring distances shall be kept to a minimum.

BCB
The BCB is normally installed in a wall-mounted box close to the battery.

Figure 6-1 Design of battery room

6.9 Battery Maintenance

For the battery maintenance and maintenance precautions, refer to IEEE-Std-1188-2005 and the relevant
manuals provided by the battery manufacturer.

1. Check the battery connection screws at regular intervals. If any loose screws are found, re-tighten them immediately.

71
 S600D

2. Make sure that all the safety devices are present, in good condition and that they function correctly, and make sure that the
battery management parameter settings are correct
3. Measure and log the air temperature in the battery room.
4. Check to the battery terminals for damage or signs of heating, and that the battery enclosure and terminal shields are
intact.

For details, refer to 9.2 .

6.10 Disconnecting or Connecting Internal Battery Terminals

1. If you need to service the UPS, please be sure to disconnect cable connections between the UPS and batteries. Failure to
observe this condition may result in electric shock or battery arc risk.
2. Batteries may only be service by qualified personnel and the appropriate protective equipment and clothing must be used
at all times.

When the UPS has been fully shut down, if it is equipped with internal batteries the internal battery terminals will
remain live because there is no switch between the UPS and its internal batteries.
Use the appropriate tools to open the front cover of the battery compartment, and then disconnect the connection
between the UPS and its internal batteries. Refer to Figure 8-1 and Figure 8-3 for details. Wear arc protective gloves
and arc protective clothing when disconnecting the cabinet battery terminals and internal battery terminals. To
disconnect the internal batteries in the standard UPS, simply open the connection terminals between W101 and
W107, W102 and W106, W103 and W108; to disconnect the internal batteries in the UPS with side cabinet, simply
open the connection terminals between W101 and W107, W102 and W106, W103 and W108 first, and then open the
connection terminals between W201 and W207, W202 and W206, W203 and W208. Refer to Figure 6-2 for
instructions on disconnecting the terminals.

Once the above operations are complete, the UPS is no longer connected to its internal batteries. At
this point it is safe to carry out maintenance work on the UPS since the battery terminals are completely de-
energized.

Figure 6-2 Schematic diagram for disconnecting internal battery terminals

72
 S600D

Once the maintenance work is complete, please wear arc protective gloves and arc protective clothing when
reconnecting the cabinet battery terminals and internal battery terminals. To reconnect the internal batteries in the
standard UPS, simply restore the connection terminals between W101 and W107, W102 and W106, W103 and W108; to
reconnect the internal batteries in the UPS with side cabinet, simply restore the connection terminals between W101
and W107, W102 and W106, W103 and W108 first, and then the connection terminals between W201 and W207, W202
and W206, W203 and W208.
Use a multimeter to check and ensure that the cabinet internal battery terminal poles are correct. Finally, replace
the front cover of battery compartment.

1. If maintenance is required, wait 10 minutes for the internal DC bus capacitors to discharge.
2. Hazardous voltages may be present on some parts of the UPS, even when the rectifier input switch, bypass input switch
and battery switch are disconnected. Therefore, UPS maintenance should be carried out by qualified personnel only.

6.11 Disposal of Used Batteries

If any of the batteries are found to be leaking, place them in a suitable container that can withstand sulphuric acid
and dispose of them in accordance with local regulations.
Lead-acid batteries are classified as hazardous waste material and represent a key item in the control of battery
pollution control. Batteries must be stored, transported, used and disposed of in accordance with national and local
legal requirements and all other criteria applicable to the treatment of hazardous waste material and waste battery
pollution prevention.
According to the applicable regulations, waste lead-aid batteries must be recycled, while all other disposal methods
are prohibited. Uncontrolled or random disposal of waste lead-acid batteries, or other improper disposal methods
can result in serious environmental pollution, which will be investigated by the relevant authorities.

Chapter 7 Parallel System and LBS System

This section provides information about installing parallel and LBS systems.

7.1 General
The parallel system may include up to four UPS modules of the same power rating and connected in parallel, without
the need for a centralized mains static bypass device. The bypass static switches of the individual UPS modules
share the load when the system transfers to the mains bypass supply.
From a 'power' viewpoint, each module is internally identical to the 'single module' configuration. A parallel system
requires inter-module control signals to manage load sharing, synchronizing and bypass switching. The control
signals are connected by means of the parallel cables, which are multi-way ribbon cables connected between the
units of the system to form a ring.

7.2 System Installation Procedures

The basic installation procedure of a parallel system consisting two or more UPS modules is the same as that for a
single module system. This section only covers the installation procedures that are specific to the parallel system.
When installing a parallel UPS system, follow the installation procedures for a single UPS module, with the additional
requirements detailed in this section.

Preliminary Checks

Make sure that correct parallel cable option has been selected, and that the module ratings, model, and software
and hardware releases are consistent.

To achieve coordinated operation of the modules in the parallel system, each module must be configured separately using
the VERTIV setting software. This must be done by VERTIV service personnel.

Cabinet Installation

Place the UPS modules side by side and interconnect them as shown in Figure 7-1. The output distribution mode
(Q1EXT, Q2EXT must be configured) shown in Figure 7-1 is recommended to facilitate maintenance and system
testing.

74
 S600D

Figure 7-1 Circuit diagram of typical parallel system (with common input, separate batteries and output)

Power Cables

The power cable wiring is similar to that of the UPS module. Refer to 3.1 .
The bypass and rectifier input supplies must be use the same neutral line input terminal. If the input is fitted with a
current leakage protection device, the device must be fitted upstream of the neutral line input terminal.

The power cables (including the bypass input cables and UPS output cables) of each UPS module should be of the same
length and specifications to facilitate load sharing.

Parallel cables

Shielded and double-insulated parallel cables must be interconnected in a ring configuration between the UPS
modules, as shown in Figure 7-2. Method: connect a parallel cable between the PARA1 port on one module and the
PARA2 port on the next module. Repeat this step for all the other parallel cables.
The ring connection ensures the reliability of the control of the parallel system. Be sure to verify that the cables are
connected securely before starting up the system!

Note

7.3 Operating Procedures for Parallel Systems

Warning

Proceed one step at a time, and only move on to the next time when the current operation has been completed for
all the UPS modules in the system.

Start-up Procedures In Normal Mode

These procedures are used to start the UPS starting from the fully switched off condition, which means that neither
the UPS or the maintenance bypass switch have supplied power to the load before. Make sure UPS has been
completely installed and commissioned by the engineer, and the external power supply switch is in the off position

76
 S600D

1. These procedures result in mains voltage being applied to the UPS output terminals.
2. If any loads are connected to the UPS output terminals, check with the user that it is safe to apply power. If the load is not
ready to receive power, please disconnect the downstream load switch, and apply a warning label at the load connection point.

Use the following procedures to switch the UPS on when it is in the fully switched off state.
1. Confirm that all the external maintenance bypass switches are in the off position. Ensure that the internal
maintenance bypass switch Q3 is in the off position, and that the input cables and copper bars and the parallel
cables are connected securely.

To avoid generating spurious fault messages, whenever it is necessary to switch the maintenance bypass switch to the on or off
position, the operation must be completed within three seconds.

2. Close all the bypass input switches.

3. Close the UPS bypass input switch Q2, rectifier input switch Q1, output switch Q5 and all external output isolating
switches (if any) in that order.
At this point, the system is switched on.
4. Press the UPS power buttons one by one to start the respective inverters.

Operating Procedures in Maintenance Bypass Mode

If the UPS system consists of more then 2 UPS modules in parallel, and the load capacity exceeds the single module capacity,
do not use the internal maintenance bypass switch.

This operation will transfer the load from the UPS power supply protection state to direct connection with AC input
bypass state.

Caution: risk of interruption of power supply to load

Before performing this procedure, you should check the LED information first, and make sure the bypass is normal and
synchronized with the inverter. Failure to do so may result in a brief interruption in the power supply to the load.

1. Remove the maintenance bypass switch baffle retaining screws, rotate the baffle upwards until it is locked in
position, and then fasten the retaining screws. Refer to Figure 5-13.
At this point, the system Interlock function has been activated and the UPS will transfer to internal bypass mode;
you should confirm that the UPS has been transferred to internal bypass mode.
2. After confirming, close the maintenance bypass switch Q3.
3. Disconnect the output switch Q5. At this point the load is powered by the maintenance bypass.

When the UPS is in maintenance bypass mode, the load is not protected against abnormalities in the mains power supply.

4. Unplugging the REPO terminal deactivates the rectifier, inverter, static switch and battery, but does not affect the
maintenance bypass power supply to the load.

In maintenance mode, the load is fed directly by the mains power instead, of the pure AC power from the inverter.

5. If the UPS is equipped with an external battery, set the corresponding external battery switch to the off position
until all the UPS modules have been disconnected from the batteries.

77
 S600D

6. Disconnect the rectifier input switch Q1 and bypass input switch Q2. At this point, all the internal power supplies
are deactivated and the LCD screen is switched off.
7. If the UPS is equipped with internal batteries, make sure that that they have been isolated from the UPS before
carrying out maintenance work on it. Refer to 6.10 for details.

1. If maintenance is required, wait 10 minutes for the internal DC bus capacitors to discharge.
2. Hazardous voltages may be present on some parts of the UPS, even when the rectifier input switch, bypass input switch
and battery switch are disconnected. Therefore, UPS maintenance should be carried out by qualified personnel only.

Procedures for Isolating One UPS Module from a Parallel System

These procedures may only be carried out by VERTIV service personnel, or under their supervision.

Before operation, confirm that the system capacity has sufficient redundancy to avoid system shut down due to overload.

The following procedures apply when it is necessary to isolate one UPS module from the parallel system for repair
due to serious malfunction:
1. Unplugging the REPO terminal deactivates the rectifier, inverter, static switch and battery, while the other UPS
modules in the parallel system continue to supply the load as normal.
2. If the UPS is equipped with an external battery, simply set the corresponding external battery switch to off.
3. Set the rectifier input switch Q1, bypass input switch Q2 and output switch Q4 to off.
At this point, all the internal power supplies are deactivated and the LCD screen is switched off.
4. If the UPS is equipped with internal batteries, make sure that that they have been isolated from the UPS before
carrying out maintenance work on it. Refer to 6.10 .

1. Post a label on the AC input distribution line (generally at a distance from the UPS) to alert personnel that UPS
maintenance is in progress.
2. Wait 10 minutes for the internal DC bus capacitors to discharge. Then the UPS is completely shut down.

Procedures for Inserting One UPS Module into a Parallel System

These procedures may only be carried out by VERTIV service personnel, or under their supervision.

The following procedures are used to reintegrate a UPS module that has been previously isolated from the parallel
system:
1. If the UPS his equipped with internal batteries, be sure to restore the connection between the UPS and internal
batteries after completing maintenance work on the UPS. Refer to 6.10 for details. Next, close the rectifier input
switch Q1.
At this point, the system is switched on.
2. Close the bypass input switch Q2.
3. Close the output switch Q5, and press the power button for two seconds.

In order to shut the UPS down completely and disconnect the power supply to the load, proceed as follows: All
power switches, isolating switches and breakers are switched to off, and the UPS no longer supplies power to the
load.

The following procedures will interrupt the power supply to the load, switching it off.

1. Unplug the REPO terminal on each UPS to deactivate the rectifier, inverter, static switch and battery.
2. If the UPS is equipped with an external battery, set the corresponding external battery switch to the off position
until all the UPS modules have been disconnected from the batteries.
3. Set the rectifier input switch Q1 and bypass input switch Q2 on each UPS to off. At this point, all the internal
power supplies are deactivated and the LCD screen is switched off.
4. Set the output switch Q5 on each UPS to off.
5. If the UPS his equipped with internal batteries, be sure to open the connection between the UPS and internal
batteries.

1. Post a label on the AC input distribution line (generally at a distance from the UPS) to alert personnel that UPS maintenance
is in progress.
2. Wait 10 minutes for the internal DC bus capacitors to discharge. Then the UPS is completely shut down.

Warning: hazardous battery voltage

Hazardous voltages are still present on the battery terminals, even after the UPS has been shut down.

Procedures for Shutting Down the UPS Completely While Maintaining Power to the Load

The following procedures may be used to shut the UPS down completely are applicable for completely, while
maintaining the power supply to the load. Refer to the procedures in 7.3.2 .

7.4 LBS System

Cabinet Installation

An LBS system consists of two independent UPS systems, each consisting of two parallel UPS modules, as shown in
Figure 7-3. The LBS system provides high reliability, which makes it suitable for use with loads having multiple input
terminals. In the case of single-input loads, an STS may be installed to power the load.
The system uses the LBS cables to synchronise the outputs of two independent (or parallel) UPS systems.
Place the UPS modules side by side and interconnect the UPS modules according to the following instructions.

Power Cables

The power cable of dual-bus power system is similar to that of single system. Refer to 3.1 Connecting the Power
Cables.

LBS Cable

1. The appearance of the LBS port is the same as the parallel port (see Figure 3-6).
2. In the case of dual bus systems consisting of parallel UPS units, we recommend preparing two LBS cables for connecting
any two parallel/LBS ports of the two parallel system, in order to guarantee a secure connection.

Figure 7-6 LBS parameter settings interface

The LBS is the load synchronisation system, and is used to synchronise the output voltage phases of the two
sections of the UPS system. The two sections of the UPS system may consist of two single UPS units, or two UPS
parallel systems.
'Master' and 'Slave' may be set-up manually via the LCD screen.
The UPS selected as the LBS master can send synchronization signals to LBS slave based on its inverter voltage
phase. After the slave receives the synchronization signal sent by the master, it will adjust its inverter voltage phase
so that it is synchronised with the master.
Thanks to this system, it is possible to synchronise the two sections of the UPS system, guaranteeing reliable
transfer between the respective output voltages and the STS, and hence a reliable, uninterrupted power supply to
the load.

8.2 SIC Card

Figure 8-8 shows the appearance of the SIC card.

Figure 8-8 SIC card

The SIC card is a network management card. It may be used to provide network communication capability on
VERTIV designed UPS modules. It can also be connected to the IRM series sensor to provide environment
monitoring functions. When the intelligent device generates an alarm, the SIC card can notify the user by logging
the event, sending captured information, and generating an email message.
Preparation
1. Prepare the installation tools, including a cross head screwdriver.
2. Check that all installation materials are present and complete, including an SIC card.

84
 S600D
Procedures

The SIC card is hot pluggable, therefore there is no need to shut the UPS down when installing it.

Some of the electronic components on the SIC card static sensitive, therefore, avoid touching the components or circuit on
the SIC card with bare hands or other conductive materials, so as to protect the SIC card against static shock. When removing
or installing the SIC card, hold the card by its edges.

The SIC card should be installed in the Intellislot port (see Figure 3-6) on the UPS.
Installation procedure:
1. Remove the cover from the Intellislot port. Keep the screws for future use.
2. Insert the SIC card (along two sides of the Intellislot port) into the port position, and then fasten the screws.
For more information about the SIC card, refer to the bSite Interface Web/SNMP Agent Card User Manual, which is
available as an accessory.
Refer to 3.2.8 for information about wiring and routing the signal cables.

Relay Card

The UPS is available with a relay card that enables users to use dry contact signals to monitor the UPS. It is hot
pluggable for easy installation.
The relay card can provide up to four digital relay output signals for connection to remote monitoring devices.
These signals are: UPS on Battery, Battery Low, UPS on Bypass or in Standby, UPS Faulty. Each dry contact signal
output channel provides both normally open and normally closed ports. The relay card can also handle up to three
digital signal inputs, two of which control the UPS switch-on and switch-off functions, while the third is reserved.
Appearance and description of hardware
The appearance of the relay card is shown in Figure 8-9.

2. Insert the relay card into the UPS.

The relay card is hot-pluggable, therefore it may be installed without shutting the UPS down.

a) Remove the Intellislot port cover (see Figure 3-6) on the front panel. Do not throw the screws away.
b) Align the relay card with the Intellislot port, insert the relay card into the port along the grooves on both sides of
the port.
c) Secure the relay card in place through the fixing holes on the relay card panel using the screws from step a).
3. Connect the cable.
You can select an optional cable according to your needs, or prepare your own, in accordance with Table 8-4 and
Figure 8-10 - Figure 8-12. Connect the cable end with the DB25 male connector to the DB25 connector of the relay
card, and the other end to the user equipment.

The DB25 connector must be connected to a SELV circuit. Failure to observe this could damage the relay card and even
lead to accidents.

Use the following procedures to switch the UPS on when it is in the fully switched off state.
1. Ensure that the internal maintenance bypass switch Q3 is off, and that the input cables and copper bars are
connected securely. Ensure that the input cables and copper bars are connected securely according to the 3-in 1-
out power distribution mode configuration.

To avoid generating spurious fault messages, whenever it is necessary to switch the maintenance bypass switch to the on or off
position, the operation must be completed within three seconds.

2. Before switching the system on, use a multimeter to measure the voltage on the rectifier terminals (mA-mB-mC),
and make sure that there are no circuits; if so, check that the connections are correct.
3. Unplug the REPO terminal at rear of the cabinet, and then close the rectifier input switch Q1, at this point the
system is switched on.

4. Press , and access -> Settings (default password is ‘111111’) -> Output -> Output phase No., then set the
system to ‘1 phase’. After the system is switched off, switch it on again, access this menu once more and confirm
that this setting has been applied.

Figure 8-20 Prompt window

5. Set the rectifier input switch Q1 to the off position to shut the UPS down completely.
6. Plug-in the REPO terminal, close the UPS bypass input switch Q2 and the rectifier input switch Q1 in that order.
At this point, the system is switched on.
7. After the rectifier starts, close the output switch Q5 and all the external output isolation switches (if any).
8. Press the power button for two seconds to start the inverter.

Chapter 9 Service And Maintenance

This section focuses on UPS maintenance, including fan maintenance, battery maintenance, UPS cleaning, UPS
state checks, and UPS function checks.

Never attempt to carry out maintenance on the UPS while it is on line. Ensure that the UPS has been switched off completely
when performing any internal maintenance operations on it.

9.1 Fan Maintenance

In order to avoid injury or damaging the device, wait until the fan is completely stationary before inserting fingers or any tools
into it.

The UPS fans are expected to run for 20,000 hours - 40,000 hours in continuous operation. The higher the ambient
temperature, the shorter the fan life.
During the UPS operation, it is important to check the condition of the fans at least once a year by confirming that
they blow air out of the ventilation holes on the rear panel.

9.2 Battery Maintenance

1. Never invert the battery connections as this could result in fires.

2. Never attempt to open batteries since they contain electrolyte which is potentially harmful to personnel. In the event of
accidental with electrolyte, wash the affected area with abundant, clean water, and seek medical assistance immediately.

The internal UPS battery module houses a sealed, lead-acid, maintenance-free battery. The battery life depends on
the ambient temperature, and charge and discharge times. High ambient temperatures and heavy discharge cycles
will shorten the battery life.
To preserve the battery life, it is necessary to:
Maintain the ambient temperature between 15°C and 25°C
Prevent small current discharge. DO NOT operate the UPS in battery mode for periods in excess of 24 hours.
Charge the battery for at least 12 hours if it hasn't been charged for three months while the ambient temperature
remains within the specified limits, or two months in the event of high ambient temperatures

1. Check the battery connection screws at regular intervals, and re-tighten them if necessary.
2. Make sure that all the safety devices are present, in good condition and that they function correctly, and make sure that the
battery management parameter settings are correct.
3. Measure and log the ambient temperature in the battery room.
4. Check whether the battery terminals are damaged or hot, and check the condition of the cases and the covers.

If any of the batteries are found to be leaking, place them in a suitable container and dispose of them in accordance
with local regulations.
Lead-acid batteries are classified as hazardous waste material. The control of waste battery pollution is a nationally
important issue. Batteries must be stored, transported, used and disposed of in accordance with national and local
legal requirements and all other criteria applicable to the treatment of hazardous waste material and waste battery
pollution prevention.

92
 S600D
According to the applicable regulations, waste lead-aid batteries must be recycled, while all other disposal methods
are prohibited. Uncontrolled or random disposal of waste lead-acid batteries, or other improper disposal methods
can result in serious environmental pollution, which will be investigated by the relevant authorities.
As a provider of lead-acid batteries, VERTIV has developed a dedicated service network and waste battery recycling
system to assist users to dispose of waste batteries legally. Contact VERTIV or your nearest service centre for
detailed information about the waste battery the recycling system.
VERTIV may not be held liable for the environmental impact resulting from the failure to comply with the guidelines
set out in this section, or to use the waste battery recycling system offered by VERTIV.

9.3 Cleaning the UPS

Clean the UPS periodically, especially the ventilation holes, to ensure free airflow inside the UPS. If necessary, clean
the UPS with a vacuum cleaner. Confirm that the ventilation holes are unobstructed.

9.4 Checking the UPS Status

We recommend checking the operational state of the UPS at least twice a year.
Check the following items:
1. Check for any UPS fault conditions: Is the FAULT indicator on? Are there any UPS alarms active?
2. Check if the UPS is operating in Bypass mode. Under normal conditions, the UPS operates in Normal mode; if you
find that it is operating in Bypass mode, determine the reason (operator intervention, overload, internal fault, etc.)
3. Check if the battery is discharging: When the AC mains supply is within normal limits, the battery should not be
discharging; if you find that it is operating in Bypass mode, determine the reason (mains failure, battery test,
operator intervention, etc.)

9.5 Checking the UPS Functions

Checking the UPS functions may interrupt the power supply to the load!

We recommend checking the UPS functions at least twice a year.

Backup the load data before conducting the UPS functional check. The procedures are as follows:
1. Press the power button to check if the buzzer beeps, the indicators are on and the LCD display is normal.
2. Press the power key and check again that the indicators are on, the LCD display is normal, and that the UPS has
been transferred to inverter mode.
