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 supplies power to the loads via the bypass. The UPS is operating in
Bypass mode.
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 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.

www.powershield.com.au 13
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) To keep the system reliable, the UPS will perform the battery self-test automatically periodically.
The default setting period is once per week.
3) Users also can set battery self-test through monitoring software.
4) 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.

www.powershield.com.au 14
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 fault code 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
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: JP1 setting on the control board: please shorts the Pin5 & Pin6 and Pin7 & Pin8 for 20 pcs
batteries; shorts the Pin5 & Pin6 or Pin7 & Pin8 for 19 pcs batteries; and keeps every pin open for 18 pcs
