4.1 Battery Connections
The following illustrations details the wiring connections between the UPS and the

DANGER
Contacts are not rated with interrupting capacity. DO NOT attempt to connect the
UPS to the Battery Cabinet without having the MCCB switch on the rear panel of the
Battery Unit, in the OFF position.
4.2 14kVA/18kVA illustration
The following diagram shows the rear view of a 14kVA / 18kVA UPS and 18kVA
Battery Cabinet. NOTE: Use only compatible cabinets! Refer to page 8.
4.3 Connection Procedure
1) Ensure all power is locked and tagged out.
2) Remove the Battery Connector cover mounted on the top of the UPS back panel.
3) Plug the DC Connectors of the Battery unit into the DC Connector socket on the
UPS unit (see power connections section 3.1).
4.4 Charger Connection
Battery Cabinet model UE31-BC-1825 requires 240V connection between the UPS and
Battery Cabinet for battery charging. This connection is made from CN14A of the
Battery Cabinet to CN14 of the UPS (and CN14A of battery cabinet 2 to CN24 of
battery cabinet 1 if paralleling cabinets). NOTE: Without this connection the battery
cabinet will not be able to charge its batteries, thus preventing extended backup
time during a power outage.
