x Alarms	This alarm is triggered by one of the
	following events:
Inverter Startup
Failure	• The UPS detects that at least one
	electronics module failed to
	complete its startup sequence as
	expected and was most likely shut
	down. In this situation, the alarm is
	more of a general status indicator.
	It should be accompanied by
	another alarm, indicating the
	reason for the modules failure to
	start.
	• An electronics module has briefly
	(for approximately one-quarter of a
	second) disconnected from the
	system and is attempting to restart.
	In this situation, no other alarms
	associated with this failure will
	occur, with the exception of a
	possible Internal Communications
	Failure alarm.

The electronics module may not be fully seated. Remove the bezels and ensure that each of the electronics modules is fully inserted into the chassis.

An autocalibration is required, and the UPS will automatically schedule the autocalibration process on detection of this condition.
