Installation and configuration  30 
Connecting the ERM to the UPS 
Connect both ends of the split ERM cable to the ERM connectors on the UPS rear panel. To install additional 
ERMs, connect both ends of the split ERM cable from the next ERM into the connectors on the rear panel of 
the previous ERM. Up to four ERM units can be connected. 
 
 
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. 
 
 
IMPORTANT: To verify the attached ERMs are recognized, confirm the number of installed ERMs 
using the UPS front panel control via the UPS Status Menu.
