The MTP T 15HD A WM and MTP T 15HD A D can be installed in a one-gang electrical wall
box, with the MTP T 15HD A D fitting into a Decora wall plate cover (supplied). If a suitable
wall box is already installed, follow steps 5 through 8 on the following page. To install a new
wall box or to install using the included mud ring, follow all the steps below. UL-listed wall
boxes are recommended.
The installation must conform to national and local electrical codes and to the size
requirements of the wall plate.
The following UL requirements pertain to the installation of the MTP T 15HD A architectural
series into a wall or furniture.

•

These units are not to be connected to a centralized DC power source or used beyond
their rated voltage range.

•

These units must be installed in UL-listed junction boxes.

•

These units must be installed with conduit in accordance with the National Electrical
Code.

Preparing the Site and Installing the Wall Box

Choose a location that allows cable runs without interference. Allow enough depth for
both the wall box and the cables. The box should be at least 2.5 inches (6.4 cm) deep
to accommodate the connectors and cables. Install the cables into the wall, furniture, or
conduits before installing the wall plate.

If a wall box is not available to use for a template, use the dimensions from the template
on page

or download a full size template online at

www.extron.com

If installing directly into furniture, cut out the center portion of the template.

Place the template (or the wall box) against the installation surface, and mark the
guidelines for the opening.

Cut out the material from the marked area.

Insert the wall box into the opening. The box or the rear connectors of the wall plate
should fit easily into the opening. Enlarge or smooth the edges of the opening as
needed.
