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 line input breaker at
“ON” position(for dual input unit,
also set the bypass input breaker at “ON”). 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

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
