2) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
3) After a few seconds, the UPS will enter into the AC mode. In case of abnormal utility power, the UPS will transfer to battery
mode operation to provide uninterrupted power to the outlets.
Note: In battery mode, the UPS will shut down automatically when the remaining charge is low. Once the utility power is
restored, the UPS will restart automatically in AC mode.
2. Turn on the UPS without utility power (Battery mode)
1) Make sure that the battery pack breaker is in its ON position.
2) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
3) After a few seconds, the UPS will be turned on and begin operating on “off-grid” or Battery mode.
3. Connecting devices to the UPS
After the UPS is turned on, you can connect devices to the unit.
1) Turn on the UPS first and then start powering one load at a time only after all of them have been plugged into the unit. The total
load level will be displayed on the LCD panel.
2) Should you need to connect inductive loads, 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 energy consumption increases during initial power on.
3) If the UPS is overloaded, the buzzer will beep twice every second.
4) In the event of an overload, all unnecessary loads must be removed one by one, to lower the total loads connected to the UPS to
less than 80% of its nominal power capacity to prevent the overload condition.
5) If the overload time exceeds the time specified in AC mode, the UPS will automatically transfer to Bypass mode. After the
overload is removed, the UPS will return to AC mode. If the overload time exceeds the time specified in Battery mode, the UPS
will transfer to fault status. At this time, if the bypass is enabled, the UPS will supply power to the loads using the bypass mode.
If the bypass function is disabled or the input power is not within the bypass acceptable range, the output power will be cut off
immediately.
4. Charging the batteries
1) Once the UPS is connected to utility power, the unit will charge the batteries automatically, except when the UPS is running in
Battery mode or while the battery self-test is in progress.
2) It is recommended to charge the batteries at least 10 hours before use to ensure proper backup time.
3) Verify that battery number setting on the control board is consistent with the actual quantity of units being connected.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to the battery capacity.
a. If the battery capacity is over 25%, the buzzer will beep once every 4 seconds.
b. If the battery voltage drops to the alarm triggering level, the buzzer will beep once every second to indicate that the battery has
reached its lowest capacity, and that the UPS will soon shut down automatically. Shutting down non-critical loads at this point
will disable the alarm and prolong the backup time. If the programmable timer function is enabled, the UPS will shut off program-
mable output terminals automatically.
Note: Should there be no more loads to turn off, you will need to shut down all existing connected equipment as soon as
possible to protect it or save the data. There is the risk of data loss or load failure if battery runtime is exceeded.
2) To silence the buzzer sound in Battery mode, press the Mute button.
3) The backup time varies depending upon the capacity of the external batteries being used.
4) When the backup time is set at 16.5 hours (LCD panel default value), the UPS will shut down automatically to protect the battery
after the discharging period expires. This battery discharge protection can be enabled or disabled using the LCD panel control.
6. Testing the batteries
1) To check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode, press the Test button to initiate the
self-diagnostic tool.
2) To maintain the system reliability, the UPS will perform an automatic battery self-test on a periodic basis. The default setting for
the battery self -test is once per week.
3) Battery self-test interval can also be set through the monitoring software.
4) When the UPS is in battery self-test mode, the LCD Display and buzzer indication will be the same as in battery mode, with the
exception that the battery LED will appear blinking in this case.
7. Turn off the UPS with utility power in AC mode
1) Turn off the inverter of the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once and the UPS will
go into Bypass mode.
Note 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utility power to the output terminal even
though the UPS (inverter) has been turned off.
Note 2: After turning off the UPS, please beware that the UPS is operating in Bypass mode and there is a risk of power loss for
connected devices.
2) In Bypass mode, output voltage of the UPS is still present. In order to shut off the output voltage, switch off the input breaker to
the UPS. A few seconds later, there will be no display shown on the LCD panel while the UPS is now completely turned off.
8. Turn off the UPS without utility power supply in Battery mode
1) Turn off the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once.
2) The UPS will cut off power to the output, in which case there will be no indication showing on the display panel.
9. Muting the buzzer
1) To silence the buzzer, press the Mute button for at least 0.5 second. If you press it again, the buzzer will be enabled.
2) Some warning alarms cannot be muted unless the error that triggered them is fixed.
10. Operation in warning status

Note: In battery mode, the UPS will shut down automatically when the remaining charge is low. Once the utility power is
restored, the UPS will restart automatically in AC mode.
2. Turn on the UPS without utility power (Battery mode)
1) Make sure that the battery pack breaker is in its ON position.
2) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
3) After a few seconds, the UPS will be turned on and begin operating on “off-grid” or Battery mode.
3. Connecting devices to the UPS
After the UPS is turned on, you can connect devices to the unit.
1) Turn on the UPS first and then start powering one load at a time only after all of them have been plugged into the unit. The total
load level will be displayed on the LCD panel.
2) Should you need to connect inductive loads, 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 energy consumption increases during initial power on.
3) If the UPS is overloaded, the buzzer will beep twice every second.
4) In the event of an overload, all unnecessary loads must be removed one by one, to lower the total loads connected to the UPS to
less than 80% of its nominal power capacity to prevent the overload condition.
5) If the overload time exceeds the time specified in AC mode, the UPS will automatically transfer to Bypass mode. After the
overload is removed, the UPS will return to AC mode. If the overload time exceeds the time specified in Battery mode, the UPS
will transfer to fault status. At this time, if the bypass is enabled, the UPS will supply power to the loads using the bypass mode.
If the bypass function is disabled or the input power is not within the bypass acceptable range, the output power will be cut off
immediately.
4. Charging the batteries
1) Once the UPS is connected to utility power, the unit will charge the batteries automatically, except when the UPS is running in
Battery mode or while the battery self-test is in progress.
2) It is recommended to charge the batteries at least 10 hours before use to ensure proper backup time.
3) Verify that battery number setting on the control board is consistent with the actual quantity of units being connected.
5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to the battery capacity.
a. If the battery capacity is over 25%, the buzzer will beep once every 4 seconds.
b. If the battery voltage drops to the alarm triggering level, the buzzer will beep once every second to indicate that the battery has
reached its lowest capacity, and that the UPS will soon shut down automatically. Shutting down non-critical loads at this point
will disable the alarm and prolong the backup time. If the programmable timer function is enabled, the UPS will shut off program-
mable output terminals automatically.
Note: Should there be no more loads to turn off, you will need to shut down all existing connected equipment as soon as
possible to protect it or save the data. There is the risk of data loss or load failure if battery runtime is exceeded.
2) To silence the buzzer sound in Battery mode, press the Mute button.
3) The backup time varies depending upon the capacity of the external batteries being used.
4) When the backup time is set at 16.5 hours (LCD panel default value), the UPS will shut down automatically to protect the battery
after the discharging period expires. This battery discharge protection can be enabled or disabled using the LCD panel control.
6. Testing the batteries
1) To check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode, press the Test button to initiate the
self-diagnostic tool.
2) To maintain the system reliability, the UPS will perform an automatic battery self-test on a periodic basis. The default setting for
the battery self -test is once per week.
3) Battery self-test interval can also be set through the monitoring software.
4) When the UPS is in battery self-test mode, the LCD Display and buzzer indication will be the same as in battery mode, with the
exception that the battery LED will appear blinking in this case.
7. Turn off the UPS with utility power in AC mode
1) Turn off the inverter of the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once and the UPS will
go into Bypass mode.
Note 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utility power to the output terminal even
though the UPS (inverter) has been turned off.
Note 2: After turning off the UPS, please beware that the UPS is operating in Bypass mode and there is a risk of power loss for
connected devices.
2) In Bypass mode, output voltage of the UPS is still present. In order to shut off the output voltage, switch off the input breaker to
the UPS. A few seconds later, there will be no display shown on the LCD panel while the UPS is now completely turned off.
8. Turn off the UPS without utility power supply in Battery mode
1) Turn off the UPS by pressing the OFF button for at least 0.5 second. The buzzer will beep once.
2) The UPS will cut off power to the output, in which case there will be no indication showing on the display panel.
9. Muting the buzzer
1) To silence the buzzer, press the Mute button for at least 0.5 second. If you press it again, the buzzer will be enabled.
2) Some warning alarms cannot be muted unless the error that triggered them is fixed.
10. Operation in warning status
1) When the Fault LED flashes and the buzzer beeps once every second, it means that the UPS is experiencing operation issues.
Fault codes are available via the LCD panel. Refer to the troubleshooting table for additional details.
2) Some warning alarms cannot be muted unless the error that triggered them is fixed.
11. Operation in fault mode
1) When the Fault LED illuminates and the buzzer beeps continuously, it means that there is a fatal error in the UPS. Fault codes are
available via the LCD panel. Refer to the Troubleshooting table for additional details.
2) Check the loads, wiring, ventilation, utility, battery and so on when a fault occurs. Do not try to turn on the UPS again before
solving the problems. If the issues persist, contact the dealer or service personnel immediately.
3) In case of emergency, disconnect the UPS from the utility, external battery, and output immediately to avoid danger.
12. Changing battery numbers
1) This operation should only be performed by trained and qualified technicians.
2) Turn off the UPS. If the load cannot be shut down, remove the cover from the maintenance bypass switch on the rear panel of
the unit, and slide the maintenance switch to the BPS position.
3) Switch off the input breaker and battery breaker.
4) Remove the UPS cabinet cover. Disconnect the battery wire and modify the jumper on the control board to set the battery
numbers, as shown on the table below.
5) Modify the battery pack to match the setting number in control panel.
6) Then, modify charger voltage according to the table below to match the setting number on the control board. There are 5
jumpers on the charger board. Please refer to the below table to modify charger voltage.
7) After executing the previous steps, replace the UPS cover. Switch on the battery breaker followed by the input breaker. The UPS
will enter into the Bypass mode. If the UPS is in maintenance Bypass mode, turn the maintenance switch to the UPS position
before turning on the system.
13. Changing charging current
1) This operation should only be performed by trained and qualified technicians.
2) Turn off the UPS. If the load could not be cut off, you should remove the cover of maintenance bypass switch on the rear panel
and turn the maintenance switch to the BPS position first.
3) Switch off the input breaker and then do the same with the battery breaker.
4) Remove the cabinet cover and disconnect battery wire. Then modify the jumpers on the charger board to set the charging
current (refer to table below). Be careful that the maximum setting should not exceed the charging current acceptable for the
battery.
3.5 Parallel system operation
1. Parallel system installation
If the UPS is only available for single operation, you may skip this section to the next.
1) Install and wire the UPS units according to section 3.5.2 in this manual.
2) Connect the output wires of each UPS to an output breaker or maintenance bypass switch with an output breaker
(sold separately).
3) Connect all output breakers to a maintenance bypass switch with breaker.
4) Each UPS must be connected to its own power bank. In the event a single power bank is used for all the UPS units, it will cause
permanent damage to the equipment.
5) Remove the cover of the 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 again.
6) Refer to the following wiring diagram.

2. Parallel system connection
NOTE: For parallel installation each UPS must have a maintenance bypass output breaker/switch connected. This device is offered
separately.
1) Once you have verified all wiring has been done properly, turn off the input, output and battery breakers of each UPS.
2) Remove all the maintenance bypass covers and change the maintenance switches from UPS to BPS, turn on the input breaker
of the each UPS and change the maintenance switches from BPS to UPS. When done, replace the maintenance bypass cover.
With a multimeter, measure the L1-N1 and L2-N2 voltage difference between each UPS. If the voltage difference is less than
2V, it means all connections are correct. If the difference is higher than 2V, check if the wiring has been done correctly.
3) Turn on the input breakers of each UPS in the parallel system. Before turning on each UPS in turns, check if PAR001~PAR003
are displayed in each UPS sequentially. If no “PARXX exists in any UPS, please check if the parallel cables are connected
correctly.
4) Turn on each UPS one by one and make sure that AC mode LED or Battery mode LED display is lit in each UPS. Using a
multimeter, measure the output voltage of each UPS to make sure the voltage difference is less than 2V (typical 1V). If the
difference is above 2V, check that parallel cables and/ or parallel current cables are connected properly. If all connections are
done properly, it may be a UPS internal issue. In this case, contact your local distributor or service center for help.
5) Turn off each UPS in sequence. After all of the UPS are transferred to Bypass mode, turn on the output breaker of each unit.
6) Finish by turning on the UPS units in AC mode. Now the system is ready for operation in parallel mode.
3. Adding one new unit into the parallel system
1) You cannot add one new unit into the parallel system while the whole system is running. First, all loads and each UPS in the
system must be shutdown.
2) Make sure all of the UPS are parallel models, and follow the wiring scheme shown earlier in this manual.
3) Install the new UPS and follow instructions in the previous section for proper connection, testing and startup.

4. Removing one unit from the parallel system
There are two methods that can be used to remove one UPS from the parallel system:
First method:
1) Press the OFF button twice for about 0.5 second each. The UPS will enter into bypass mode without output.
2) After turning off the output breaker, do the same with the input breaker of the UPS.
3) After the UPS shuts down, turn off the battery breaker. Then remove the parallel cable and share current cable. You can now
remove the unit out from the parallel system.
Second method:
1) If the bypass is abnormal, the UPS cannot be removed without interruption. You must first power down the load and complete
ly shut down the UPS system.
2) Enable the Bypass setting in each UPS and then power off the running UPS. All UPS units in the parallel system will transfer to
Bypass mode. Remove all maintenance bypass covers and change the maintenance switches from UPS to BPS. Next, turn off
input breakers and battery breakers.
3) Remove the desired UPS.
4) Turn on the input breaker of the remaining UPS units and the system will transfer to Bypass mode.
5) Set the maintenance switches from BPS to UPS and replace the maintenance bypass covers. Turn on the remaining UPS units
and finish the parallel system connections.
Warning: (parallel system only)
• Before turning on the parallel system to activate the inverter, make sure that every maintenance switch on the UPS is in the same
position.
• When the parallel system is turned on to operate through the inverter, do not change the maintenance switch of any unit.

4. Troubleshooting guide
If the UPS system does not operate correctly, use the table below to troubleshoot the problem.
Charge the UPS for at least 7 hours before storing the unit. Cover the UPS, and place it upright in a cool, dry location. During
storage, recharge the battery in accordance with the following table:
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.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and the required precau-
tions. Keep unauthorized personnel away from 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.
A battery can present a risk of electric shock and high short circuit current. The following precaution should be observed when
working on batteries:
- Remove watches, rings or other metal objects.
- Use tools with insulated handles.
Replace batteries with the same type and number of units.
Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The batteries must be properly
deposed according to local regulations.
Do not open or destroy batteries. Released electrolyte is highly poisonous and harmful to the skin and eyes.
Replace the fuse only with the same type and amperage in order to avoid fire hazards.
Do not disassemble the UPS system.
