7.2.2Parallel UPS shutdown with load transfer on manual bypass (Q2)

The purpose of this procedure is to supply the load directly by mains through manual bypass Q2.

This procedure is normally performed when the UPS must be completely switched OFF for maintenance or service purpose, performed by an authorized Service Center.

1.Switch OFF the inverter on each unit entering the screen:

MENU/COMMAND MENU/INVERTER OFF

Attention: to switch OFF permanently the inverter the key Enter must be pressed 2 times.

The output will be supplied by the mains through all automatic bypass.

2.Switch ON the maintenance bypass Q2 (I) on each unit.
