  • Page 14 Operation 3.1.1.2 Battery Circuit Breaker The battery circuit breaker on the front panel must be ON before the UPS can charge the batteries or receive battery back-up power. It opens and closes the circuit between the battery unit and the UPS. If the ac input circuit breaker is OFF or tripped and the battery circuit breaker on the front panel is ON, the UPS will drain the batteries until the batteries reach a predetermined low-voltage level.

    Operation 3.1.1.3 Alarm Silence Button When the audio alarm is activated, it can be silenced by pushing the alarm silence button. This button is located next to the ac input circuit breaker. Pressing the alarm silence button does not silence the audio alarm permanently. The audio alarm will be activated again the next time the UPS has an alarm condition.

    Operation If the battery voltage continues to drop, the UPS will eventually stop operating and the load will be dropped. After the UPS stops operating, it will wait 3 hours for the return of the normal ac line power. If the normal ac line power returns within 3 hours, the UPS will turn on automatically.
