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.
