Step 1: The BatteryPack Option board is provided with a wiring harness for connection
between the BatteryPack and the right I/O board. Install the Unison BatteryPack
Option cable harness and connector into the ERn enclosure.
N o t e : An ERn enclosure supports the use of either the Unison RideThru Option (URTO)
or the Unison BatteryPack Option (UBPO), but not both in the same enclosure.
N o t e : The BatteryPack Option kit is intended for use only in wall mount ERn enclosures
and is not compatible with rack mounted enclosures.
The BatteryPack Option (UBPO) kit provides battery
power during power outages to the Paradigm
Architectural Control Processor for up to 90 minutes (ERn
with a single P-ACP) or up to 45 minutes (ERn4 with two
Paradigm ACPs). The self-contained battery installs on
the bottom of the ERn enclosure.
