Rack Options
Unison ERn options include the RideThru Option (URTO) kit, BatteryPack Option kit (UBPO), Ethernet
Switch Module (ERn-NET), and the Redundant Rack Power Supply (ERn-RPS).
Additionally you may use a Station Repeater Module in the ERn4 enclosure top module slot instead of
a secondary Paradigm Station Power Module. See

Module

.
Install the RideThru Option (URTO) Kit
The RideThru Option kit (URTO) provides power to the Paradigm Architectural Control Processor for a
minimum of 12 seconds during brief power outages or power drop outs. The Ride Through option
board fully charges and is ready for operation within ten minutes of the ERn enclosure being powered.
WARNING:
Risk of Electric Shock! The Unison RideThru Option board retains an electrical
charge even when power to the ERn enclosure is off.
Note:
A single 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.
Note:
One Unison RideThru Option board powers one Paradigm ACP. therefore an ERn4
enclosure with two Paradigm ACPs installed requires two RideThru Option boards.
