3-4. Single UPS Operation

1. Turn on the UPS with utility power supply (in AC mode)

1) After power supply is connected correctly, set the breaker of the battery pack at “ON” position (the
step only available for long-run model). Then set the input breaker at “ON” position. At this time
the fan is running and the UPS enter to power on mode for initialization, several seconds later, UPS
operates in Bypass mode and supplies power to the loads via the bypass.

NOTE: When UPS is in Bypass mode, the output voltage will directly power from utility after you
switch on the input breaker. In Bypass mode, the load is not protected by UPS. To protect your
precious devices, you should turn on the UPS. Refer to next step.

2) Press and hold the “ON” button for 0.5s to turn on the UPS and the buzzer will beep once.

3) A few seconds later, the UPS will enter to AC mode. If the utility power is abnormal, the UPS will
operate in Battery mode without interruption.

NOTE: When the UPS is running out battery, it will shut down automatically at Battery mode. When the
utility power is restored, the UPS will auto restart in AC mode.

2. Turn on the UPS without utility power supply (in Battery mode)

1) Make sure that the breaker of the battery pack is at “ON” position (only for long-run model).

2) Press the “ON” button to set up the power supply for the UPS, UPS will enter to power on mode.
After initialization UPS will enter to No Output mode, then Press and hold the “ON” button for 0.5s
to turn on the UPS, and the buzzer will beep once.

3) A few seconds later, the UPS will be turned on and enter to Battery mode.

3. Connect devices to UPS

After the UPS is turned on, you can connect devices to the UPS.

1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total
load level.

2) If it is necessary to connect the inductive loads such as a printer, the in-rush current should be
calculated carefully to see if it meets the capacity of the UPS, because the power consumption of
this kind of loads is too big.

3) If the UPS is overload, the buzzer will beep twice every second.

4) When the UPS is overload, please remove some loads immediately. It is recommended to have the
total loads connected to the UPS less than 80% of its nominal power capacity to prevent overload
for system safety.

5) If the overload time is over acceptable time listed in spec at AC mode, the UPS will automatically
transfer to Bypass mode. After the overload is removed, it will return to AC mode. If the overload
time is over acceptable time listed in spec at Battery mode, the UPS will become fault status. At this
time, if bypass is enabled, the UPS will power to the load via bypass. If bypass function is disabled
or the input power is not within bypass acceptable range, it will cut off output directly.

4. Charge the batteries

1) After the UPS is connected to the utility power, the charger will charge the batteries automatically
except in Battery mode or during battery self-test.

2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be
shorter than expected time.

3) Make sure the battery numbers setting on the control board (Please refer to the section 3-4-12 for
detailed setting) is consistent to real connection.

5. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the

17

battery capacity is more than 25%, the buzzer will beep once every 4 seconds; If the battery
voltage drops to the alarm level, the buzzer will beep quickly (once every sec) to remind users that
the battery is at low level and the UPS will shut down automatically soon. Users could switch off
some non-critical loads to disable the shutdown alarm and prolong the backup time (the UPS would
cut off the programmable output terminal automatically when the programmable timer function is
enabled). If there is no more load to be switched off at that time, you have to shut down all loads
as soon as possible to protect the devices or save data. Otherwise, there is a risk of data loss or
load failure.

2) In Battery mode, if buzzer sound annoys, users can press the Mute button to disable the buzzer.

3) The backup time of the long-run model depends on the external battery capacity.

4) The backup time may vary from different environment temperature and load type.

5) When setting backup time for 16.5 hours (default value from LCD panel), after discharging 16.5
hours, UPS will shut down automatically to protect the battery. This battery discharge protection
can be enabled or disabled through LCD panel control. (Refer to 3-7 LCD setting section)

6. Test the batteries

1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode,
you could press the “Test” button to let the UPS do battery self-test.

2) Users also can set battery self-test through monitoring software.

3) If the UPS is at battery self-test, the LCD display and buzzer indication will be the same as at
Battery mode except that the battery LED is flashing.

7. Turn off the UPS with utility power supply in AC mode

1) Turn off the inverter of the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will
beep once. The UPS will turn into Bypass mode.

NOTE 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utility
power to output sockets and terminal even though you have turned off the UPS (inverter).

NOTE 2: After turning off the UPS, please be aware that the UPS is working at Bypass mode and
there is risk of power loss for connected devices.

2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch off
the input breaker. A few seconds later, there is no display shown on the display panel and UPS is
complete off.

8. Turn off the UPS without utility power supply in Battery mode

1) Turn off the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep once.

2) Then UPS will cut off power to output and there is no display shown on the display panel.

9. Mute the buzzer

1) To mute the buzzer, please press the “Mute” button for at least 0.5s. If you press it again after the
buzzer is muted, the buzzer will beep again.

2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for the
details.

10. Operation in warning status

1) When Fault LED flashes and the buzzer beeps once every second, it means that there are some
problems for UPS operation. Users can get the warning indicator from LCD panel. Please check the
trouble shooting table in chapter 4 for details.

2) Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for the
details.

11. Operation in Fault mode

1) When Fault LED illuminates and the buzzer beeps continuously, it means that there is a fatal error in
the UPS. Users can get the fault code from display panel. Please check the trouble shooting table

18

in chapter 4 for details.

2) Please check the loads, wiring, ventilation, utility, battery and so on after the fault occurs. Don’t try

to turn on the UPS again before solving the problems. If the problems can’t be fixed, please contact

the distributor or service people immediately.

3) For emergency case, please cut off the connection from utility, external battery, and output
immediately to avoid more risk or danger.

12. Operation of changing battery numbers

1) This operation is only available for professional or qualified technicians.

2) Turn off the UPS. If the load couldn’t be cut off, you should remove the cover of maintenance
bypass switch on the rear panel and turn the maintenance switch to “BPS” position first.

3) Switch off the input breaker, and switch off the battery breaker (only available for long-run model).

4) Remove the cabinet, and then modify the jumper on the control board to set the battery numbers
(refer to NOTE below). Then disconnect battery wire for standard model and modify the battery
pack carefully. After complete the changes, put the cabinet back.

NOTE: JS3 setting on the control board: please shorts the Pin1 & Pin2 for 18 pcs batteries; shorts
the Pin3 & Pin4 for 19 pcs batteries; and shorts the Pin5 & Pin6 for 20 pcs batteries.

5) Switch on the input breaker and the UPS will enter Bypass mode. If the UPS is in maintenance
Bypass mode, turn the maintenance switch to “UPS” position and then turn on the UPS.

3-5. Parallel Operation

1. Parallel system initial startup

First of all, please make sure all of the UPSs are parallel models and have the same

configuration.

1) Turn on each UPS to AC mode respectively (Refer to section 3-4(1)). Then, measure
the output voltage of each UPS to check if the voltage difference between actual
output and setting value is less than 1.5V (typical 1V) with multimeter. If the
difference is more than 1.5V, please calibrate the voltage by configuring inverter
voltage adjustment (Refer to Program 15, section 3-7) in LCD setting. If voltage
difference remains more than 1.5V after calibration, please contact your local
distributor or service center for help.

2) Calibrate the output voltage measurement by configuring output voltage calibration
(Refer to Program 16, section 3-7) in LCD setting to make sure the error between real
output voltage and detected value of UPS is less than 1V.

3) Turn off each UPS (Refer to section 3-4(7.)). Then, follow the wiring procedure in
section 2-4.

4) Remove the cover of parallel share current cable port on the UPS, connect each UPS
one by one with the parallel cable and share current cable, and then screw the cover
back.

5) Turn on the parallel system in AC mode:

a) Turn on the input breaker of each UPS. After all UPSs enter to bypass mode,

measure the voltage between output L1 of each UPS and output L2 of each UPS. If
these two voltage differences are all less than 1V, that means all connections are
correct. Otherwise, please check if the wirings are connected correctly.

b) Turn on the output breaker of each UPS.
c) Turn on each UPS in turns. After a while, the UPSs will enter to AC mode

synchronously and then, the parallel system is completed.

6) Turn on the parallel system in Battery mode:

a) Turn on the battery breaker (only available in long-run model) and output breaker of

each UPS.

NOTE: It’s not allowed to share one battery pack for long-run UPSs in parallel system.

19

Each UPS should be connected to its battery pack.

b) Turn on any UPS. A few seconds later, the UPS will enter to battery mode.

c) Then, turn on another UPS. A few seconds later, the UPS will enter to battery mode

and add to the parallel system.

d) If you have the third UPS, follow the same procedure of c). Then, the parallel system

is complete.

If more detailed information is needed, please contact supplier or service center for parallel
operation instruction.

2. Add one new unit into the parallel system

1) You can not add one new unit into the parallel system when whole system is running. You must cut
off the load and shutdown the system.

2) Make sure all of the UPS are the parallel models, and follow the wiring refer to section 2-4.

3) Install the new parallel system refers to the previous section.

3. Remove one unit from the parallel system

There are two methods to remove one unit from the parallel system:

First method:

1) Press the “OFF” key twice and each time should be lasted for more than 0.5s. Then, the UPS will

enter into bypass mode or no output mode without output.

2) Turn off the output breaker of this unit, and then turn off the input breaker of this unit.

3) After it shuts down, you can turn off the battery breaker (for long-run model) and remove the

parallel and share current cables. And then remove the unit from the parallel system.

Second method:

1) If the bypass is abnormal, you can not remove the UPS without interruption. You must cut off the

load and shut down the system first.

2) Make sure the bypass setting is enabled in each UPS and then turn off the running system. All UPSs

will transfer to Bypass mode. Remove all the maintenance bypass covers and set the maintenance
switches from “UPS” to “BPS”. Turn off all the input breakers and battery breakers in parallel system.

3) Turn off the output breaker and remove the parallel cable and share current cable of the UPS which

you want to remove. Then, remove it from parallel system.

4) Turn on the input breaker of the remaining UPS and the system will transfer to Bypass mode. Set

the maintenance switches from “BPS” to “UPS and put the maintenance bypass covers back.

5) Turn on the remaining UPS according to the previous section.

5-2. Maintenance

The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified

maintenance personnel.

Even after the unit is disconnected from the mains, components inside the UPS system are still

connected to the battery packs which are potentially dangerous.

Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that
no current is present and no hazardous voltage exists in the terminals of high capability capacitor such as
BUS-capacitors.

Only persons are adequately familiar with batteries and with the required precautionary measures
may replace batteries and supervise operations. Unauthorized persons must be kept well away from the
batteries.

Verify that no voltage between the battery terminals and the ground is present before maintenance
or repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may
occur between the battery terminals and the ground.

Batteries may cause electric shock and have a high short-circuit current. Please remove all
wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools
with insulated grips and handles for maintaining or repairing.

When replace the batteries, install the same number and same type of batteries.

Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The
batteries must be rightly deposed according to local regulation.

Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may
be toxic.

Please replace the fuse only with the same type and amperage in order to avoid fire hazards.

Do not disassemble the UPS system.
