input going out of acceptable range.

At this time the batteries will dis-

charge until the input is restored to an

acceptable range.

Note: Runtime is limited in duration.

Prepare to shut down the Symmetra

PX UPS and the load equipment or

restore incoming voltage.

Shutdown or unable to

transfer to batt due to

down because an overload occurred

and bypass is not available.

Option 1: Reduce the load to elimi-

nate overload.

Option 2: If possible, add power

modules to eliminate overload.

Option 3: Replace failed power mod-

ules to eliminate overload.
