Note:

A single DRd enclosure supports the use of either the Unison ride thru option
(URTO) kit or the Unison battery pack option (UBPO) kit, but not both in the same
enclosure.

Install the Battery Pack Option Kit

The battery pack option kit is provided with a battery pack and a wiring harness with a four pin
connector. The battery pack also includes a battery cable lead which must be connected to the battery
prior to installation.

The wiring harness splits into two twisted pairs of cable with a two pin connector on each end. The
shorter of the two twisted pairs connects to the right I/O board of either a host DRd or ERn enclosure.
The longer of the two twisted pairs is used specifically for installation in an ERn4 top position right I/O
board. Cable tie this twisted pair back and out of the way when it is not required.

Connect Battery Cable

The battery cable is left disconnected when shipped from the factory and should be connected prior to
installation.

Step 1: Temporarily remove the six screws securing the cover to the battery pack.
Step 2: Locate the loose red battery cable lead and attach it to the spade receptacle on the

battery.

Note:

Step 3: Replace the cover and secure it with the six screws previously removed.

You might find it easier to lift the battery up slightly from the container to fit the
spade onto the receptacle.

Install Battery Pack

Step 1: Install the wiring harness into the enclosure (the connector is keyed to ensure proper

orientation). Harness installation into the enclosure is similar for both a host DRd and a
host ERn enclosure.

a: Insert the connector end through the opening in the bottom of the enclosure. The

connector is designed to snap into place without additional hardware, therefore slight
force may be required to ensure the connector installs properly.

Step 2: Connect to the right I/O board.
