Unison Battery Pack Option Kit
Note:
Overview
The 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 to the
enclosure.
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 a host DRd or ERn enclosure. The longer of the
two twisted pairs is only for installation in an ERn4 top position Right I/O board.
