Switching on the ERM circuit breaker

Charging the ERM batteries

Connect the UPS to a grounded utility power outlet. When the UPS is plugged in, it automatically enters

Standby mode and begins charging the ERM batteries. With the UPS in Standby mode, allow the ERM

batteries to charge for at least 24 hours before putting the UPS into service.

CAUTION:

To ensure maximum runtime, be sure to configure the UPS ("

on page

) for the number of installed ERMs using the UPS front panel controls.
