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.
