I. GENERAL DESCRIPTION
1.1 Introduction
TESCOM DS300SHP Series Uninterruptible Power Supplies are double-conversion;

on-line UPSʼs manufactured with the latest IGBT and PWM technology, to produce an
uninterruptible, fully DSP (Digital Signal Processor) controlled pure sine wave output to
critical loads.
TESCOM DS300SHP Series units are 3-phase in/3-phase out devices, and they are
installed between a three phase critical load, and a 3-phase+N mains supply
The advantages of using DS300SHP UPS:
• Power blackout protection:
If the mains power fails, the UPS continues to supply the critical load using the
energy stored in its batteries, keeping the load immune from power disturbances.
• Increased power quality:
The UPS has its own internal voltage and frequency regulating software, which
ensures that, its output to the critical load is maintained within close tolerances, independent
of voltage and frequency variations on the mains power lines.
• Fully digital control by three DSP controller for each UPS:
The UPS is controlled by 3 independent DSP chips which are communicating each
other continuously. Rectifier, Inverter and User Interface modules have separate DSPʼs to
achieve the highest performance. Each DSP module has many parameters to control and
monitor the system to have the best electrical power output and to help diagnostic.
• Increased noise rejection:
By rectifying the input AC power to DC power and then converting it back to AC

(Double-Conversion) any electrical noise present on the input mains supply line is effectively
isolated from the UPS output. Therefore the critical load is supplied with only clean and
uninterrupted AC power.

1.2.1 DESCRIPTION OF BLOCKS
RECTIFIER: In DS300SHP Series UPSs, a DSP controlled IGBT rectifier with PWM technique is used to
increase input power factor (PFC) and to decrease input current harmonics (THDI).
The 3-level IGBT rectifier accepts 3-phase AC input and produces a dual polarity DC voltage for both
supplying the inverter and charging the batteries.
BATTERIES: Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In
DS300SHP Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC
supply.
Batteries are discharged by the inverter during mains failure. The discharged batteries are re-charged by
the IGBT Rectifier on a constant voltage / current limiting basis, if AC mains power is available.
INVERTER: It is manufactured by using the latest IPM and DSP (Digital Signal Processing) technologies,
and Pulse Width Modulation (PWM) technique. The Inverter converts the DC BUS voltage supplied by the
IGBT Rectifier and / or the batteries into a well regulated, fully digital controlled 3-phase AC voltage with
fixed voltage and frequency.
The output of the inverter is used to supply the critical loads connected to the UPS output.
STATIC TRANSFER SWITCH (STATIC BYPASS): This is an electronically controlled transfer switch,
which enables the critical load to be connected either to inverter output or to by-pass power source. During
normal operation, the load is supplied by the inverter output, but in case of an overload or a UPS failure it is
automatically transferred to the bypass source without any interruption.
MAINTENANCE BYPASS SWITCH (MBS): This is a manually controlled mechanical switch, which is used
to supply the critical load, using the bypass source, when the UPS is shut down for maintenance or
troubleshooting purposes.
The load is unprotected against mains supply disturbances and black-outs when it is connected to either
static or maintenance bypass supply.
1.2.2. OPERATING CONDITIONS OF UPS
UPS may be in one of the following operating conditions:
A. Normal Operation (If Mains supply is available):

All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is supplied
by the Inverter Output. During normal operation, the Rectifier supplies DC power to the Inverter and
charges the Batteries at the same time.
B. Battery Operation :
The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or AC
input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the inverter
operation is supplied by the batteries. Therefore the AC voltage output supplying the critical load is not
interrupted, until the batteries are fully discharged. At the end of the discharging time the inverter is turned
off and it start again automatically, together with the rectifier, when the mains power is restored, and the
UPS returns o normal operation.
The Rectifier is also turned off and inverter operates on batteries during automatic or manual battery test
procedure.
C. By-Pass Operation :
If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the load to
the bypass supply without any interruption, provided that the bypass supply is available and within the
tolerated limits regarding voltage and frequency. At the end of the overloading period, if the fault condition
is restored, static switch transfers the critical load again to the inverter output. Note that, during operation
from the bypass supply, the critical load may be effected by any possible disturbances or power failure in
the bypass supply.

2. Install the UPS in a protected area with adequate air flow and free of excessive dust.
3. You must therefore allow for a minimum gap of 250 mm behind the unit to allow adequate air flow
4. Select a suitable place (temperature between 0°C and 40°C) and the relative humidity (%90 max)
5. It is recommended to place the equipment in an air-conditioned the room (24°C)
6. Temperature is a major factor in determining the battery life and capacity. Keep batteries away from
main heat sources or main air inlets etc.
7. In case of an operating the UPS in a dusty place, clean the air with a suitable air filtration system.
8. Keep out of your equipment from explosive and flammable items.
9. Avoid direct sunlight, rain, and high humidity.
WARNING!!! Check the capacity of the forklift if it is available for lifting.

DO NOT LEAN OR LIFT THE UPS CABINET AFTER THE BATTERIES HAVE BEEN
INSTALLED.
11
2.4 Connecting the UPS Power Cables
WARNING!!! A separate power line should be used to supply the UPS AC input. Never use the same
line to supply another electrical device. Do not use any additional cable to increase the
length of the UPSʼs input cable. It is advised to use an MCCB suitable for the input current
on the UPSʼs input line.
The connection of the electrical panel should be supplied by a grounded outlet. Otherwise, the UPS
and the load connected to the output will be left ungrounded. The grounding system must
be checked, and must be strengthen if required. Potential difference between ground and
neutral must be less than 3V AC.
Descriptions of the UPS input output cable connection terminals are shown in figure 2.1

2.7 Battery Installation

WARNING!!! Be careful while connecting batteries.
ATTENTION!!! Open the battery switch/fuse before making any connection on the batteries.
The batteries associated with the UPS equipment are usually contained in a purpose-built battery cabinet.
In DS300SHP Series 10-15 and 20 KVA UPSs, there is enough space for 60 pieces of 12V 5-7-9Ah
maintenance free batteries.
Where battery racks are used, they should be sited and assembled in accordance with the battery
manufacturerʼs recommendations. In general, batteries require a well-ventilated, clean and dry environment
at reasonable temperatures to obtain efficient battery operation.
In general a minimum space of 10 mm must be left on all vertical sides of the battery block. A minimum
clearance of 20 mm should be allowed between the cell surface and any walls. All metal racks and cabinets
must be earthed.
1. Unpack each battery and check its terminal voltage with a suitable load. Any battery with terminal
voltage less than 10,5V must be charged before installation.
2. Please check the battery connecting hardware and documents. (cables, trays, connection diagrams)
3. Please locate suitable number of batteries on each rack, according to the battery installation and
connection diagram given with the unit.
4. Start locating the batteries from top to the bottom on the racks.
5. Be careful about the connection between the racks and polarities.
6. After interconnecting the batteries, connect “+”, “0” and “-“ leads of the batteries to the battery input
terminals on the UPS. Be careful to connect the batteries correctly and do not turn on (S5) before
checking all connections and before starting the UPS. In DS300SHP Series UPS, 60 blocks of
batteries are connected in series, in such a way that they form two strings of batteries with opposite
polarity; with a center tap connection to the NEUTRAL (N1-N2) internally.
NOTE THAT SEPARATE CABLES FROM EACH BATTERY GROUP SHOULD BE CONNECTED TO K2
TERMINALS TO FORM THE MIDPOINT CONNECTION.
WARNING!!! NEVER TURN ON S5 (BATTERY FUSE) WITHOUT CENTER POINT CONNECTION TO K2.

3.3 Alarms and warning messages

The internal structure of the DS300SHP Series UPS is modular, these are:
-PFC Rectifier module
-Inverter module
-Front panel module
Module alarms and warnings are cathegorized according to modules at the front of the Alarm or warning
message module information is added:
-RXX Rectifier alarms and warnings
-AXX Inverter alarms and warnings
-LXX LCD front panel alarms and warnings
More then one alarm can be shown on the UPS front panel with time shared order. If 4 alarms are occurred
at the same time every 2 seconds 1 message will be showed, next 2 seconds 2.message will be showed
etc..
If A00 or R00 Alarm is shown on the LCD panel we understand that there is a system fault at the related
module. We saw the message in the A00 INV FAULT = XXXX or R00 PFC FAULT = XXXX format.
Numbers shown in X determines the status code which tells the problem to us. See status code table for
details of codes.

IV. OPERATING INSTRUCTIONS
4.1 INTRODUCTION
After all the electrical connections of UPS have been made and while all the circuit breakers and switchtes
of the device are turned OFF (at “0” position);
1. Check the polarities of battery connections:

K1 : + V (nominal voltage +360V, float charge voltage +405V)
K2-K2 : 0 V (common terminal for ʻʼ+ʼʼ and ʻʼ-ʻʼ battery groups)
K3 : - V (nominal voltage -360V, float charge voltage -405V)
2. Check 3-phase AC input and neutral connections (care should be taken fort he phase order).
ATTENTION!!! TWO CABLES FOR EACH BATTERY GROUP SHOULD BE USED FOR EXTERNAL
BATTERY CONNECTION, AND THE COMMON POINT CONNECTION SHOULD BE MADE ON K2
TERMİNAL BLOCK!
WARNING ! : UPS should never be operated without neutral connection.
3. Check the output load connections of UPS.
4.2 OPERATING UPS IN ONLINE MODE
4.2.1 Starting UPS from a completely shut down position:
1. Turn ON S1 (AC Input) switch (switch to ʻʼ1ʼʼ position)

2. Turn ON S2 (Bypass) switch (switch to ʻʼ1ʼʼ position)
3. Turn ON S4 (AC Output) switch (switch to ʻʼ1ʼʼ position)
ATTENTION!!! BYPASS VOLTAGE WILL BE CONNECTED TO THE OUTPUT TERMINALS OF

UPS WHEN THE ON/OFF SWITCH (S7) IS SWITCHED ON !
4. Turn on S7 (On/Off) switch (to ʻʼ1ʼʼ position). LCD panel activates, and ʻʼINV RESET” or “PFC RESETʼʼ
message appears on the display meaning that the rectifier starts to operate.
5. A few seconds later red bypass light (L2) on front panel turns off and gren inverter light (L6) turns on.
L6 light indicates that the UPS has started normal operation and generating uninterruptable power for
the critical load.
6. Turn on S5 switch (to “1” position) to connect the battery group to UPS.
7. UPS is ready and in normal operation now.
4.2.2 Shutting down the UPS
After closing all the critical loads supplied by the UPS output:
1. Turn off S4 (AC Output) switch (to ʻʼ0ʼʼ position).

2. Turn off S7 (On/Off) switch (to ʻʼ0ʼʼ position).
3. Turn off S5 (Battery) switch (to ʻʼ0ʼʼ position).
4. Turn off S2 (Bypass) switch (to ʻʼ0ʼʼ position).
5. Turn off S1 (AC Input) switch (to ʻʼ0ʼʼ position).
After performing the above procedure, UPS is completetely shut-down. In this case PFC rectifier and
inverter is not operating and the batteries are not being charged.
45
44
4.2.3 Switching the UPS from a Normal Operation to Maintenance Bypass Condition
1. Enter COMMANDS menu by using UP and DOWN buttons on front panel during normal operation.
Select ENTER<BYPASS> command by using again the UP and DOWN buttons and pres ENTER
button. The critical load is transferred to bypass supply in this case and it is shown at LCD display with
“A09 MANUAL BYPASS” message. Besides L6 (load on UPS) light on front panel will be off and L2
light (bypass) will be on.
2. Turn on S3 (Maintenance Bypass) switch (after unlocking and taking away the padlock on it) to ʻʼ1ʼʼ
position.
3. Turn off S7, S5, S1, S2 and S4 switches (to ʻʼ0ʼʼ position).
In this case, bypass voltage is connected directly to the output of UPS and the critical load is supplied via
maintenance bypass switch. No AC or DC supply is connected to the inside and the circuits of UPS.
4.2.4 Switching the UPS from a Maintenance Bypass Condition to Normal Operation
1. Turn on S1 (AC Input) switch (to ʻʼ1ʼʼ position).

2. Turn on S2 (Bypass) switch (to ʻʼ1ʼʼ position).
3. Turn on S4 (AC Output) switch (to ʻʼ1ʼʼ position).
4. Turn on S7 (On/Off) switch (to ʻʼ1ʼʼ position). LCD panel activates, and main menu will appear at the
display. Also “A08 ON MAINTENANCE” message shown and the inverter will not start yet.
5. Turn off S3 (Maintenance Bypass) switch (to ʻʼ0ʼʼ position). Inverter will start automatically following the
turning off of S3 switch.
6. Connect the batteries by turning on S5 (Battery) switch (to ʻʼ1” position).
Now UPS is ready for uninterruptable operation.
4.3 UPS Behavior During Mains Outage
When the mains voltage is not available " R02 LINE FAILURE " message appears on LCD display. Sound
warning on and off is heard at the same time. UPS continues to supply the critical loads by converting the
battery voltage to AC voltage and provides operation without data losses or any other fault. Battery
autonomy time may be prolonged by shutting down the unnecessary loads for that moment.
But do not turn on these loads again during battery operation.
After a short period of time when the line voltage is available again, UPS returns to normal operation
automatically and the alarm message on the display disappears.
Shut down the critical loads in a period of minimum possible autonomy time (depends on the Ah capacity,
charge status, age of the batteries, actual load percentage of UPS and the ambient temperature).
Otherwise critical loads will be out of power at the end of battery autonomy time.
“A26 BATTERY LOW” message appears first on front panel display during battery operation if battery
voltage drops below a defined level.
“A10 BATTERY LOW SHUT” message appears on front panel display when the battery voltage drops to
the end of discharge voltage and UPS shuts itself down. Critical loads will be out of electrical power.
If a reserved generator in the system and if itʼs available, that will start to supply the necessary electrical
power to UPS input and batteries start to be charged immediately. By means of using UPS together with a
immediately available generator system, battery discharge time decreases and so they will be charged
quickly after a mains outage.

V. PARALLEL OPERATION (DS - SHP MODELS)

5.1 Introduction
Two (or more) identical DS300SHP series UPSs can be interconnected for parallel operation.
The main purposes for parallel use of DS300SHP series UPSs are:
-Redundancy for Increased Reliability

-Power Increase
Although recent UPS designs are perfect and have high MTBF figures, a second (or more) UPS can be
used in parallel with the first one, for supplying the critical load in case of any possible failure of the first
UPS. In such an application the faulty UPS is isolated automatically from the parallel system and the other
UPS (or UPSs) continues to supply the critical load. Use of Redundant UPSs in parallel, therefore, provides
increased reliability for the critical load connected to the parallel system output.
If power demand increases in a certain UPS application exceeding the power rating of an already
installed stand-alone UPS, a second (or more) UPS of the same model and power rating can be added in
parallel to the existing UPS to increase the output power capacity.
Schematic diagram of parallel connection of two DS300SHP series UPS units is shown in Figure 4.1

Figure 4.1 Parallel Connection of two UPSs
47
The AC inputs of all UPSs in the parallel system are connected to the same mains, and all the AC
outputs are connected to each other. Each UPS has its own battery group. The critical load is connected to
the common output of the parallel system. There are also some signal cable connections between the UPS
units necessary for parallel operation, and will be described later.
5.2 Parallel Operation Mode settings of DS300SHP Series UPSs
NOTE: Parallel operation hardware (parallel communication board) are not installed in a
standard DS300SHP series UPS, but parallel operation option is available and can easily
be added to all UPSs.
N+1 REDUNDANT parallel operation
For parallel operation some parameters must be given by the service personnel these are:
1- Select Parallel mode must be selected from ADJUST MENU (ADJUST MENU/INV FACTORY
OPTIONS/OPERATING MODE:)
2- A unique UPS network no must be given from ADJUST MENU(ADJUST MENU/INV FACTORY
OPTIONS/UPS NO:) (each UPS must be assigned a unique UPS number)
3- Minimum UPS quantity requirement must be given from ADJUST MENU (ADJUST MENU/INV
FACTORY OPTIONS/N+1 MINIMUM:) (N number in the system)
Shown parameters can not be adjust by the user, these parameters are located on ADJUST MENU also
adjust menu is password protected only authorized service personnel can access this menu.
PARALLEL mode
This mode is used for operation of at least two (1+1 configuration) UPS units connected in parallel for
increased reliability. If this mode is selected, the load is shared equally by each UPS available in the
parallel system (N+1 numbers of UPS units), during normal operation.
In case of a failure of any one of the UPS units, the faulty UPS is isolated from the parallel system and
the critical load is supplied by the remaining N number of UPSs. If any one of those UPS units fails too,
then the critical load is transferred to bypass supply via the static bypass switches of the parallel connected
UPSs. If the faulty UPS returns to normal operation, it joins the parallel system again and starts sharing the
load.
In parallel mode, the total VA rating of the parallel system is equal to the VA rating of a single UPS
multiplied by N.
In parallel mode, you will see ʻʼPARALLEL MODE /MSʼʼ(master UPS) or ʻʼPARALLEL MODE /slʼʼ (slave
UPS) message on the LCD panels of all the all UPS units.
More detailed diagrams for two (or more) DS300SHP series UPSs connected in parallel are given in
Figures 4.2 and 4.3
Communication between parallel UPSs are provided over one pair cable (PCC06). The length of the cable
is limited up to six meters.
A link cable is used for connecting the first UPS to the last UPS ,this cable is redundant for normal
communication cables.
If communication is lost on SLAVE UPS the UPS will shutdown but the MASTER UPS will go on running if
the communication is provided at SLAVE UPS it will start automatically again.

VI. PARALLEL OPERATING INSTRUCTIONS (DS - SHP MODELS)
6.1 INTRODUCTION
After all the electrical connections of UPS have been made and while all the circuit breakers and switchtes
of the device are turned OFF (at “0” position);
4. Check the polarities of battery connections:

K1 : + V (nominal voltage +360V, float charge voltage +405V)
K2-K2 : 0 V (common terminal for ʻʼ+ʼʼ and ʻʼ-ʻʼ battery groups)
K3 : - V (nominal voltage -360V, float charge voltage -405V)
5. Check 3-phase AC input and neutral connections (care should be taken fort he phase order).
ATTENTION!!! TWO CABLES FOR EACH BATTERY GROUP SHOULD BE USED FOR EXTERNAL
BATTERY CONNECTION, AND THE COMMON POINT CONNECTION SHOULD BE MADE ON K2
TERMİNAL BLOCK!
WARNING ! : UPS should never be operated without neutral connection.
6. Check the output load connections of UPS.
6.2 OPERATING INSTRUCTIONS FOR PARALLEL CONNECTED UPSs.
6.2.1 Starting UPSs from a completely shut down position:

10. Turn on S7 (On/Off) switch (to ʻʼ1ʼʼ position). LCD panel activates, and ʻʼINV RESET” or “PFC RESETʼʼ
message appears on the display meaning that the rectifier starts to operate.
12. A few seconds later red bypass light (L2) on front panel turns off and gren inverter light (L6) turns on.
L6 light indicates that the UPS has started normal operation and generating uninterruptable power for
the critical load.
After closing all the critical loads supplied by the UPSs output:

After performing the above procedure, UPSs is completetely shut-down. In this case PFC rectifier and

button. The critical load is transferred to bypass supply in this case and it is shown at LCD display with
“A09 MANUAL BYPASS” message. Besides L6 (load on UPS) light on front panel will be off and L2
light (bypass) will be on.
position.
In this case, bypass voltage is connected directly to the output of UPSs and the critical load is supplied via
maintenance bypass switch. No AC or DC supply is connected to the inside and the circuits of UPSs.
11. Turn off S3 (Maintenance Bypass) switch (to ʻʼ0ʼʼ position). Inverter will start automatically following the
turning off of S3 switch.
Now UPSs is ready for uninterruptable operation.
58
59
VII. NORMAL OPERATING INSTRUCTIONS (DS - SH MODELS)
7.1 OPERATING UPS IN ONLINE MODE
7.1.1 Starting UPS from a completely shut down position:

ATTENTION!!! BYPASS VOLTAGE WILL BE CONNECTED TO THE OUTPUT TERMINALS OF

UPS WHEN THE ON/OFF SWITCH (S7) IS SWITCHED ON !
4. Turn on S7 (On/Off) switch (to ʻʼ1ʼʼ position). LCD panel activates, and ʻʼINV RESET” or “PFC
RESETʼʼ message appears on the display meaning that the rectifier starts to operate.
5. A few seconds later red bypass light (L2) on front panel turns off and gren inverter light (L6) turns
on. L6 light indicates that the UPS has started normal operation and generating uninterruptable
power for the critical load.
After closing all the critical loads supplied by the UPS output:

After performing the above procedure, UPS is completetely shut-down. In this case PFC rectifier and
button. The critical load is transferred to bypass supply in this case and it is shown at LCD display
with “A09 MANUAL BYPASS” message. Besides L6 (load on UPS) light on front panel will be off
and L2 light (bypass) will be on.
position.
In this case, bypass voltage is connected directly to the output of UPS and the critical load is supplied via
maintenance bypass switch. No AC or DC supply is connected to the inside and the circuits of UPS.
59

5. Turn off S3 (Maintenance Bypass) switch (to ʻʼ0ʼʼ position). Inverter will start automatically following
the turning off of S3 switch.
Now UPS is ready for uninterruptable operation.
7.2 UPS Behavior During Mains Outage
When the mains voltage is not available " R02 LINE FAILURE " message appears on LCD display. Sound
warning on and off is heard at the same time. UPS continues to supply the critical loads by converting the
battery voltage to AC voltage and provides operation without data losses or any other fault. Battery
autonomy time may be prolonged by shutting down the unnecessary loads for that moment.
But do not turn on these loads again during battery operation.
After a short period of time when the line voltage is available again, UPS returns to normal operation
automatically and the alarm message on the display disappears.
Shut down the critical loads in a period of minimum possible autonomy time (depends on the Ah capacity,
charge status, age of the batteries, actual load percentage of UPS and the ambient temperature).
Otherwise critical loads will be out of power at the end of battery autonomy time.
“A26 BATTERY LOW” message appears first on front panel display during battery operation if battery
voltage drops below a defined level.
“A10 BATTERY LOW SHUT” message appears on front panel display when the battery voltage drops to
the end of discharge voltage and UPS shuts itself down. Critical loads will be out of electrical power.
If a reserved generator in the system and if itʼs available, that will start to supply the necessary electrical
power to UPS input and batteries start to be charged immediately. By means of using UPS together with a
immediately available generator system, battery discharge time decreases and so they will be charged
quickly after a mains outage.

VIII. MAINTENANCE
ATTENTION !!! There are no parts inside the UPS or battery group that needs service or maintenance
work that should be done by user. Therefore DO NOT OPEN THE COVER OF UPS. Never
touch on any terminal of battery group. There is risk of electric shock inside the UPS even
when it is completely turned off (because of energy storage components). Therefore
unauthorized openning of the UPS cabinet for repairment, maintenance etc. is not
recommended and forbidden. Otherwise serious injuries may happen.
8.1 Scheduled Maintenance
Some parts and components used inside UPS requires periodic maintenance by service personnel.
Besides, some power equipment inside the UPS need good air circulation for cooling functions. In this
case, the UPS should be cleaned against dust periodically. Cooling fans are mechanical and moving parts
and they should be checked periodically for this reason. Also the batteries should be checked periodically
that if they are in good condition or not.
DS300SHP Series UPS informs the user about these procedures when the maintenance time is up with its
3 independent hour counter as warnings:
FAN MAINTENANCE counter
BATTERY MAINTENANCE counter
GENERAL MAINTENANCE counter
This type of protective maintenance prevents small problems turning up to big failures.
DS300SHP Series UPS has been designed to require very low user maintenance work. User should
only make below maintenance procedure for long years of trouble-free operation.
8.2 Daily Checks
Observe the UPS daily and check the following:
Examine the operator control panel (front panel). Ensure that all LED indicators and parameter
measurements are normal and there is no warning or alarm messages on LCD display.
Examine that there is any sign of overheating the UPS or not.
Check the rotation of cooling fans visually.
Check if there is a remarkable change in the sound of UPS or not.
Check if air inlets of the cabinet cooling system are not congested with dust or any other foreign object.
Clean them with a vacuum cleaner if any present.
Take care not to leave any object on the UPS cabinet.
8.3 Weekly Checks
1. Examine the front panel and record the results.

2. Measure (from Measurements Menu) each of three phase voltages and record the values.
3. Measure (from Measurements Menu) UPS output current values and record the values.
4. Perform a Manual Battery Test (from Commands Menu) and check the status oft he batteries.
5. Cabinet covers may be cleaned with a soft damped (not wet) cloth.
61
Take notes if possible when you are examining the UPS. Compare the notes with previous ones and try to
determine if there is a change or not. If there is a difference between the previous notes and the new ones,
search for and record any new load added to UPS output between two records and the magnitude, place
and type of the new load, if possible. This information may help to technical authority who will search for
the cause of event in case of a failure.
If there is a remarkable difference between the records without any obvious reason, call technical service
immediately.
8.4 Annual Maintenance

Annual maintenance by authorized service should be done at least two times a year in order to provide
safe and efficient operation your UPS and battery group. UPS generates a warning message when the
maintenance time has expired.
8.5 Storage Conditions and Transportation of UPS
1- Check battery charge status by performing a manual battery test before living the UPS in a storage
place. If charge level is not high enough, leave the UPS for at least 12 hours to charge the batteries.
2- Disconnection oft he cables should be done by an authorized service personnel.
3- Batteries should be recharged once every 6 months during storage.
4- Store the UPS and the batteries in a cool and dry place.
0 0
Ideal storage temperature for UPS: 0 C to 40 C max.
0 0
Ideal storage temperature for batteries:10 C to 35 C max.
5- UPS should be fixed on its pallet for transporting. It should be carried by a forklift with ist pallet.

IX. FAULTS AND TROUBLESHOOTING
9.1 General Procedure For Fault Checking And Troubleshooting
UPS contains complicated electronic control circuits. In order to locate any fault occurring circuits, an
advanced knowledge about the circuitry and its operation principles must be known. The aim of this section
is to give the knowledge required at the first intervention.
There is no practical way to locate any possible fault. Most of the faults do not occur as a performance
decrement. Generally, the UPS operates normally or switches into by-pass mode. But in order to determine
any change in load or the system the parameters must be recorded regularly as mentioned previously.
Generally, the output voltage can deviate %2 from the predefined values. If values differ more than this
percentage then reasons must be investigated.
The following general structure must be systematically followed while trying to indicate the error:
Fault determination: First step is to record the messages, indicator panel LEDs, operating parameter
values and last status of switches. This must be done before
Fixing interventions: After recording all indications, check the meaning of the fault and alarm
messages using “The operator control indicator panel”. If anything related, follow the related procedure.
Reporting the fault: Service personal must clearly report the work done. Hence, if any other error
occurs there will be enough information to fix it.
9.2 Before Calling Service
Please check and note the following:
1- Did you read the user manual carefully and applied the procedures accordingly?
2- Are the switches and circuit breakers of UPS in their normal position?
3- Is there electric power at the UPS line connection distribution panel?
4- Did you turn the battery switch on (to “1“ position) when UPS started to operate in normal mode?
5- Which of the warning lights on front panel is (are) on?
6- Is there any change in the load level at the output of UPS?
7- Did any overload condition happen or not?
63
X. UPS REMOTE MONITORING AND CONTROL

Following external connections are available for DS300SHP Series UPSs.
• Communication by serial port connection.
• Dry contact (interface board) connections.
• Remote monitoring panel.
Using one of above communication options is satisfactory for remote monitoring and control in most of the
systems. But in some systems may use 2 or 3 of above options at the same time. In this case accessories
group produced by Tescom may help to make appropriate solutions.
10.1 Using Serial Port

One serial communication port is available on DS300SHP Series UPS cabinet (com1 and com2). This port
may be used for user communication. But in service status duty of this com port is changed and set as
service port in Options Menu.
All data of UPS can be accessed by this communication way. All the voltage and current values measured
by UPS, alarms, warning and status messages can be monitored.
Because the communication system is designed in an interactive manner, UPS may get commands from
monitoring and control units. These commands are listed below:
• Switch to BYPASS
• Switch to INVERTER
• SOUND on/off
• Adjust UPS time and date
• Quick BATTERY TEST
• BATTERY TEST until battery low alarm
• CANCEL battery test
• Turn off UPS output voltage immediately (SHUTDOWN)
• Turn off UPS output voltage after delay (WAITING SHUTDOWN)
• Turn off UPS output voltage (SHUTDOWN) and turn on UPS output voltage (WAITING RESTART)
• CANCEL SHUTDOWN
• RENAME UPS
These commands are evaluated only if REMOTE CNTRL: ON option is selected in

OPTİONS/COMMUNICATION OPTIONS menu and if user password is sent from this (com2) port.
Otherwise UPS doesnʼt perform these commands and only information can be obtained from the ports.
Special softwares are required in order to use the serial communication ports. Some of the commands
above have special functions and they can only be activated and used by operating TMON program groups
on a PC that is serially connected to UPS.
TMON program group includes softwares developed by TESCOM.
Additionally, remote monitoring and control is provided in every kind of operating systems, by using
worldwide known and continuously devoloping software programs. These softwares can be supplied from
TESCOM.
10.2 Serial Communication Port Connection Cable

The maximum length for RS232 communication cable should be 25 meters. For remote panel and UPS
connection the same pin configuration is valid. Connection terminals of RS232 cable is shown below for
com1 and com2 ports:
UPS Side Panel Side

9 Tx 2 Rx
7 Gnd 5 Gnd
6 Rx 3 Tx
64 65
10.3 Modem Connection
A DS300SHP Series UPS can be controlled through a normal telephone line by means of a remote
operator connected through a PC with modem device, who performs a phone call to the UPS connected
number. So the operator can see all parameters and control the UPS (if permitted from OPTIONS MENU).
10.3.1 Hardware Configuration
All requirements for modem connection are as follows:

• PC with modem
• WINDOWS 98
• Available UPS control software (T-MON)
• NULL modem which is connected to UPS
UPS has its command set to set NULL modem to auto answer mode. In order to do this, press ENTER
button for 3 seconds in ENTER: MODEM INIT item in COMMAND MENU after the hardware is installed.
A short beep sound warning is heard after pressing the buton. RX and TX lights of the connected modem
activates. Modem is set after this to answer external calls by telephone line. To test this, call the telephone
number that the modem is connected with another phone and listen the modem sound.
NOTE : Not all the modems are compatible with the command set on UPS. In such a case modem
should be set by connecting a PC.
10.3.2 Functioning Principle
The remote operator, by means of a PC and a modem device and using the remote connection function of
the control software, calls the UPS through the number to which this is connected.
The NULL modem device, connected to the UPS, will answer the call and convert the data coming from
UPSʼs serial port on to the telephone line. This way all measurements and controls allowed by the RS232
serial port can be carried out.
10.3.3 Modem Programming Procedure
Smart modem (SM) is the one connected to PC, and NULL Modem (NM) is the one connected to the UPS.
Standard Hayes AT programming language is the suitable language for modems. In usual applications a
modem which uses AT command set should be selected.
10.3.3.1 Smart Modem (SM) Programming
The connected modem to PC (smart modem) will be programmed from UPS control software (T-Mon)
automatically.
B0 E1 F1 M1 Q0 V1 X3
BAUD = 2400 PARITY = N WORDLEN = 8
DIAL = TONE (TONE which can be programmed)
&A3 &B1 &C1 &D0 &H1 &I0 &K1 &M4

&N0 &R2 &S0 &T5 &Y1

10.3.4 Modem – UPS Connection Cable
Connection of Smart Modem device to UPS is made with standard modem cable and itʼs supplied as
standard accessory for smart modem. This cable is required if an external modem will be used, and not
necessary for internal modems.
Connection cable between NULL Modem and UPS should be installed as follows:
UPS MODEM
DB9 Female DB25 Male
6 3
7 7
9 2
10.4 Dry Contact (Interface) Connections
Some important events of the UPS can be monitored or controlled by these connections. These functions
are listed below:
Function Description
AUX1 RELAY (OPTIONAL) Function selectable (NO-NC programmable)
AUX2 RELAY (OPTIONAL) Function selectable (NO-NC programmable)
BYPASS RELAY(OPTIONAL) Standard connection to RS232 connector (NO-NC programmable)
DIGITAL INPUT OPTIONAL (Reserved for special applications)
REPO INPUT Standard Remote Emergency Power Off input (NO-NC
programmable)
ATTENTION: Maximum 42Vac or 60Vac voltage may be applied to the dry contacts of the
interface. Dry contact relay outputs are NO (Normally Open) type, ie. the relay is
not activated if alarm is not present and the contacts are open circuit.
10.5 Remote Monitoring Panel Connection of UPS
This panel is used to control and monitor UPS remotely up to 400 m. distance from it. Panel is located in
monitoring and control room. If the distance is not longer than 25 m. RS232, if longer RS485
communication protocol is used. RS485 requires additional adapter.
Remote monitoring panel communicates UPS in a serial way and transfers information to user. Remote
panel requires 220Vac 50Hz supply voltage and it is recommended to get this supply from UPS output.

XI. EFFICIENT USAGE OF UPS IN TERMS OF ENERGY CONSUMPTION
Products should be used according to the conditions and procedures defined in the manual. When this is
made the most efficient usage of the product is guaranteed.
1. Energy efficiency means, decreasing consumed energy amount to the minimum level possible in
every step of living activities, without a decrease in quality or amount of produced work or product, and
keeping this principle permanent.
An efficiency value is said in operation of every energy consuming device. Roughly, efficiency can be
defined as the ratio of work or power -we obtain- at the output of a system, to that of -we give- at the input
of same system.
Keeping below recommendations during the selection and operation of an electric powered product,
provide more useful, economical and long-lasting usage in terms of energy efficiency. Therefore, user
profits economically, as well as supporting to create a cleaner environment and protecting our world
sources.
2. Every electric powered device is designed appropriate to a defined power level. Device capacity
should be selected according to its load requirement for an efficient operation.
3. Ensure to operate your device in convenient electrical conditions defined in technical specifications
table. It will work more efficiently in those conditions.
4. Check that operating environment is compatible to defined conditions.

5. Check if the place of installation is suitable as per the conditions mentioned in the relevant section of
the manual.
6. By means of the periodically maintenance work, faulty or unefficient components of the device may
be detected before the major failures. This results in more efficient operation and prevention of failures.
7. Usage of recyclable materials is one of a remarkable keys to more efficient energy consumption in
total. Users should dispose the expired recyclable materials (batteries, electronic components etc.)
according to local directions and laws.
