A small amount of arching may occur when connecting an EBM to the UPS. This is normal and will not harm
personnel. Insert the EBM cable into the UPS battery connector quickly and firmly.
1. Plug the EBM power cable(s) into the battery connector(s). Up to 4 EBMs may be connected to the UPS.
2. Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for each
cable.
3. Connect the battery detection cable(s) to the connector of the UPS and of the EBM(s).
