cy. When AC mains is lost the UPS goes into Inverter Mode. This alarm is sometimes accompanied by other

The Manual Off alarm happens when one or more inverters have been turned off in the group mapping
screen.
8.3.6 Phase Not Ready

another phase. This can be correct either by changing the input wiring to the AMPS80 HP or by changing the
phase in the group mapping settings screen.
