Unison® Ride Thru Option Kit Installation

Note:

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

Overview

WARNING:

The ride thru option (URTO) kit provides power to the architectural control processor for a minimum of
12 seconds during brief power outages or power drop outs. The ride thru option board fully charges and
is ready for operation within ten minutes of the host rack enclosure being powered.

Risk of Electric Shock! The Unison Ride Thru Option board retains an
electrical charge even when power to the host rack enclosure is off.

Install Into the DRd Rack Enclosure

Step 1: Align the ride thru option board to the mounting studs in the bottom of the DRd rack.

• Notice the mounting holes on the option board. Two are open ended slots used to
place the board and the remaining two standard mounting holes are used to secure
the board in place.

• Align the open ended slots to the studs located closest to the front of the rack and
rest the other end of the board on the mounting studs.

Step 2: Secure the board to the two mounting studs with the screws provided.
