3 Phase UPS Start-Up Procedures
Verify Input Power
Confirm that the voltage and frequency from the power distribution to the UPS terminals are within the normal range.
Turn On Bypass and Output Switches
Switch on SWBY (bypass) and SWOUT (output).
The UPS will operate in bypass mode.
The BYIN and BYPASS indicator LEDs on the panel will turn green and remain steadily lit.
Turn On Main Input Switch
Turn on SWIN (main circuit).
After approximately 30 seconds, the UPS will transfer to mains inverter mode.
The INPUT and INV LEDs will be green and steadily on. The yellow BYPASS LED will turn off. The BATTERY LED will flash.
Turn On the Battery Switch
After confirming that the battery polarity is correctly connected, switch on the battery breaker.
The UPS will automatically detect the battery capacity.
The INPUT and INV LEDs will remain green and on, and the yellow BATTERY LED will turn off.
