2.1 System and model description
The On-Line-Series is an uninterruptible power supply incorporating double-
converter technology. It provides perfect protection specifically for strict load.
The double-converter principle eliminates all mains power disturbances. A
rectifier converts the alternating current from the socket outlet to direct current.
This direct current charges the batteries and powers the inverter. In the event of
power failure, the maintenance-free batteries power the inverter. Thus the
inverter generates a sine wave AC power, which permanently supplies the
loads.

Designed with the proven on-line, double conversion architecture, this series of
UPS offers the greatest degree of availability in power protection and provides
continuous high-quality AC power to connect strict load, especially for the
basic equipments in some areas as: finance, communication, government,
traffic, manufacture, education and so on.

This manual is applicable to the following models:

30KS/33 40KS

Note:
You must make sure that the input and output wires and the input and output
terminals are connected tightly.

4. After having completed the installation, make sure the wiring is correct.
5. Please install the leak current protective breaker at the output power
distribution panel of the UPS if necessary.
6. To connect the load with the UPS, please turn off all the loads first, then
perform the connection and finally turn on the loads one by one.
7. No matter the UPS is connected to the utility power or not, the output of the
UPS may have electricity. The parts inside the unit may still have hazardous
voltage after turning off the UPS. To make the UPS have no output, power
off the UPS, and then disconnect the utility power supply.
8. Suggest charging the batteries for 8 hours before use. After connection, turn
the input breaker in the “ON” position, the UPS will charge the batteries
automatically. You can also use the UPS immediately without charging the
batteries first, but the backup time may be less than the standard value.

8
9. If it is necessary to connect the inductance load such as a monitor or a laser
printer to the UPS, the start-up power should be used for calculating the
capacity of the UPS, as its start-up power consumption is too big when it is
started.

3.4 Operating procedure for connecting the long backup

time model UPS with the external battery
1. The nominal DC voltage of external battery pack is 192VDC for 33 10K,
and 240VDC for 33 20K, 384VDC for 33 30K/40K. Each battery pack
consists of 16 /20/32 pieces of 12V “maintenance-free” batteries in series.
To achieve longer backup time, it is possible to connect multi-battery packs,
but the principle of “same voltage, same type” should be strictly followed.
2. For 33 10-40K UPS, the procedure of installing battery bank should be
complied with strictly. Otherwise you may encounter the hazardous of
electric shock.

★ A DC breaker must be connected between the battery pack and the UPS.
The capacity of breaker must be not less than the data specified in the general
specification as follow.
Model 33 10KS 33 20KS 33 30KS 33 40KS
Battery voltage 192 240 384 384
Battery current 55.5A 89A 83A 111A

★ Set the battery pack breaker in “OFF” position and connect the 16、20 or 32
pieces of batteries in series. And the battery wires must be follow the sheet
need:
Model 33 10K(S) 33 20K(S) 33 30KS 33 40KS
8AWG (6 6AWG 6AWG 4AWG
Battery wire
mm2) ( 16mm2) (16mm2) (25mm2)

3. To complete the connection by plugging the connector of the external battery

cable into the external battery socket of the UPS. Do not attempt to connect
any loads to the UPS now. You should connect the input power wire to the
right position first. And then set the breaker of the battery pack in the “ON”
position. After that set the input breaker in the “ON” position. The UPS
begins to charge the battery packs at the time.

4. Parallel operation
9
4.1 Brief introduction of the redundancy
N+X is currently the most reliable power supply structure. N represents the
minimum UPS number that the total load needs; X represents the redundant
UPS number, i.e. the fault UPS number that the system can handle
simultaneously. The bigger the X is, the higher reliability of the power system
is. For occasions where reliability is highly required, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 8 of them can be
connected in parallel to realize output power sharing and power redundancy.

4.2 Parallel installation

1. Users need to opt a standard 25-pin communication cable, which should
have 25 cores, corresponding stitches and shield, as the UPS parallel cable.
The length of the parallel cable is appropriate to be less than 3 m.
2. Strictly follow the stand-alone wiring requirement to perform the input
wiring of each UPS.
3. Connect the output wires of each UPS to an output breaker panel first, and
then connect the wiring to the load via the breaker panel.
4. The parallel UPS must be equipped with battery individually.
5. Please refer the figure followed to see the wiring of parallel operation. The
capacity of the breaker must be not less than the specification as follow.

Model No. Capacity of breaker

33 10KS ≥32A/250VAC
33 20KS ≥50A/250VAC
33 30KS ≥60A/250VAC
33 40KS ≥80A/250VAC

*The requirement of the output wiring is as follows:

★ When the distance between the UPSs in parallel and the breaker panel is
less than 20 meters, the difference between the wires of input & output of the
UPSs is required to be less than 20%;
★ When the distance between the UPSs in parallel and the breaker panel is
greater than 20 meters, the difference between the wires of input & output of
the UPSs is required to be less than 10%.

4.3 Operation and maintenance

10
1. To perform the general operation, follow the stand-alone operating
requirement.
2. Start up: The units transfer to INV mode simultaneously as they start up
sequentially in utility power mode.
3. Shutdown: the units shut down sequentially in INV mode. When the last one
completes the shutdown action, each unit will shut down the inverter
simultaneously and transfer to bypass mode.

7.1 Battery maintenance
1. This series UPS only requires minimal maintenance. The battery used for
standard models is valve regulated sealed lead-acid maintenance free
battery. These models require minimal repairs. The only requirement is to
charge the UPS regularly in order to maximize the expected life of the
battery. When being connected to the utility power, whether the UPS is
turned on or not, the UPS keeps charging the batteries and also offers the
protective function of overcharging and over discharging.
2. The UPS should be charged once every 4 to 6 months if it has not been used
for a long time. In the regions of hot climates, the battery should be charged
and discharged every 2 months. The standard charging time should be at
least 12 hours.
3. Under normal conditions, the battery life lasts 3 to 5 years. In case if the
battery is found not in good condition, earlier replacement should be made.
Battery replace event should be performed by qualified personnel.
4. Replace batteries with the same number and same type of batteries.
5. Keep the ambient temperature between 15℃ and 25℃.
6. Do not replace the battery individually. All the batteries should be replaced
at the same time following the instructions of the battery supplier.
7. Normally, the batteries should be charged and discharged once every 4 to 6
months. Charging should begin after the UPS shuts down automatically in
the course of discharging, the standard charging time for the standard UPS
should be at least 12 hours. Discharge the battery with the load more than
50%.

7.2 Notes for battery disposal and replacement

1. Before disposing batteries, remove conductive articles such as necklace,
wrist watches and rings.
2. If it is necessary to replace any connection cables, please purchase the
original materials from the authorized distributors or service centers, so as to
avoid overheat or spark resulting in fire due to insufficient capacity.
3. Do not dispose of batteries or battery packs in a fire, they may explode.
4. Do not open or mutilate batteries, released electrolyte is highly poisonous
and harmful to the skin and eyes.
5. Do not short the positive and negative electrodes of the battery, otherwise, it
may result in electric shock or fire.

21
6. Make sure that there is no voltage before touching the batteries. The battery
circuit is not isolated from the input potential circuit. There may be
hazardous voltage between the battery terminals and the ground.
7. Even though the input breaker is disconnected, the components inside the
UPS are still connected with the batteries, and there are potential hazardous
voltages. Therefore, before any maintenance and repairs work is carried out,
switch off the breaker of the battery pack or disconnect the jumper wire of
connecting between the batteries.
8. Batteries contain hazardous voltage and current. Battery maintenance such
as the battery replacement must be carried out by qualified personnel who
are knowledgeable about batteries. No other persons should handle the
batteries.
