2.3.5Battery Connections

The connections to be made are the positive, negative, and ground cables from the battery cabinet to the UPS. The battery cables are terminated at the positive, negative, and ground busbars. See Figure 2-1.

2.3.6Remote Emergency Power Off Connections

The control connections are available for Remote Emergency Power Off (REPO) through a customer-supplied (normally closed) pushbutton. With REPO connected, the jumper on the REPO terminal blocks must be removed. See Figure 2-1.

1.Remove the jumper from terminal block TB4 located across terminals 7 and 8.

2.Connect the remote emergency power off NC contact to terminals 7 and 8.

IMPORTANT The UPS is also equipped with a local Emergency Power Off (EPO) button on the front of the UPS cabinet. This switches all UPS critical power off. EPO or REPO should be used for emergency only!

2.3.7Battery Control Connections

The battery control connections are made with the battery control cables from the external battery cabinet to the UPS terminal block TB4-1 to TB4-4. See Figure 2-1.
