4.6 UPS Operation
4.6.1 Turn on the UPS with utility power supply
4.6.1.1 After power supply is connected correctly, connect the breaker of the battery bank. Then, set
the input breaker at “ON” position. At this time, 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.
4.6.1.2 Press and hold the button for 2s to turn on the UPS and the buzzer will beep once.
4.6.1.3 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.
