To replace the EBM(s):

Unplug the EBM power cable and battery detection cable from the UPS.
If additional EBM(s) are installed, unplug the EBM power cable and battery detection cable

Plug the EBM cable(s) into the battery connector(s). Up to four EBMs may be connected to the UPS.

Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each
cable.
