Connecting the ERM to the UPS

NOTE: To install a second ERM, plug the cable from the second ERM into the socket at the rear of the first ERM. Up to two ERM units can be connected.

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 ("Configuring the UPS" on page 28 ) for the number of installed ERMs using the UPS front panel controls.
