ETC Unison DRd Semi-Recessed User Manual

ETC® Installation Guide

Rough-in enclosure

The enclosure installs into the cavity of a wall and
secures directly to 2”x4” or 2”x6” construction.
The installation depth of the rough-in determines
how much the DRd rack will extend from the
finished surface.

Openings are provided on the rough-in enclosure,
matching the top and bottom acceptable wire
access for the DRd enclosure, allowing for
convenient conduit access and wire routing.

Extension rails (removable)

Extension rails are provided to extend the enclosure (up
to additional 2.5 inches) flush to the finished wall surface
(as required) for cover attachment. These rails can be
easily removed when they are not required.

Cover

The cover is provided to fit securely to the rough-in
enclosure or extension rails as needed. When the DRd rack
enclosure is installed with a Unison Battery Pack (UBPO), a
knockout is provided in the cover for removal as needed.

ETC Installation Guide

The dimensions in the table below are provided for the
rough-in only and do not include the cover or DRd rack
measurements for depth.

It is recommended that you install the rough-in at least
36” (915mm) off the floor surface to ensure clear view
of the user interface.

The wall framing and blocking must be strong enough
to hold the semi-recessed kit and DRd rack fully
populated with modules, conduit and wire
(approximately 140 lbs / 63.5kg).

The weights noted below are specific to the rough-in
only and do not include conduit, hardware, cable, rack
and module weights.

For accurate, application-specific, DRd rack enclosure
and module weights, reference the Unison DRd Rack
Enclosure Installation Manual.

DRd Semi-Recessed Installation Kit

Prepare for Installation

Where to Install the Rough-in

The DRd Semi-Recessed installation kit is designed to allow installation of a DRd rack into a wall cavity,
between 2”x4” or 2”x6” framed wall studs. The installation depth of the rough-in enclosure determines
how much the DRd rack enclosure will extend from the finished surface.

CAUTION:

Unison DRd rack enclosures require at least 17” (432mm) of front clearance and 6”
(152mm) of clearance to the left of the DRd rack door hinge from walls or other
equipment to allow for installation and removal of modules after installation.

If you do not allow this clearance, energization, operation and maintenance of your
DRd rack enclosure will be significantly difficult.

DRd Rack Enclosure Specification and Installation

Reference the DRd Rack Enclosure Installation Manual for rack installation details, including all
mechanical, electrical and control wire requirements.
