System Start-Up from Manual Bypass Operation

If the UPS has been operating in manual bypass operation and no power is connected to the UPS, the UPS display will be inactive. To re-start the system from manual bypass and achieve on-line operation, close Q1 in the external maintenance bypass panel. This will power up the internal power supply. Wait for the display to become active and follow the screen-prompted instructions.

CAUTION!

Follow these instructions carefully. Failure to do so could result in equipment damage.
