3-4. 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.
www.powershield.com.au 13
Page 15
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
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.
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).

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. Each UPS
should be connected to its battery pack.

7-2. 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.
