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). When setting input breaker at "ON" position, the fan will start running.
Then, set the internal output breaker at "ON" position. The UPS will supply power to the loads via the
bypass. Now, the UPS is operating in Bypass mode.
NOTE 1: When UPS is in Bypass mode, the output voltage will directly power from utility after you switch on
the input breaker and internal output 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
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 charging 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.
