Under fault conditions, the Fault indicators will be illuminated indefinitely while the battery charger
is operational, or for a maximum of 5 minutes while the battery charger is not operational.
If a problem persists, consult your local dealer, Liebert representative or contact the Liebert World-
wide Support Group. Please have the UPS model number and serial number available at the time of
your inquiry.
All audible alarms can be silenced, with the exception of Low Battery, Bypass Reminder and Missing
Batteries at Startup alarms. Once silenced, the alarm will not sound again until a new alarm condi-
tion is present.
