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). 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.
