6.1 "BACK UP" (slow alarm)

When in BACK UP mode, the YELLOW LED illuminates and the UPS sounds an audible alarm. The alarm stops when the UPS returns to LINE NORMAL operation.

Press the on/off/test/silence button during on-battery alarms to stop the beeping.

6.2 "LOW BATTERY" (rapid alarm)

In BACK UP mode, when the battery energy runs low, the UPS beeps rapidly until the UPS shuts down from battery exhaustion or returns to LINE NORMAL operation.

6.3 "OVERLOAD" (continuous alarm)

When the UPS is overloaded (the connected loads exceed the maximum rated capacity) the UPS emits continuous alarm to warn a overload condition. Disconnect nonessential load equipment from UPS to eliminate the overload.
