Preparing the site and installing the mounting
bracket (mud ring) or wall box
Choose a location that allows cable runs without interference.
Allow enough depth for both the wall box and the cables. You
may need to install the cables into the wall, furniture, or
conduits before installing the control panel.
The installation must conform to national and local electrical
codes and to the equipment’s size requirements. A cutout
template that shows the cutout requirement for the circuitry
enclosure on the rear of the control panel is provided in
appendix A.
CAUTION The templates provided in this manual are not to
scale. They are provided for reference only.
Extron recommends installation using a UL listed wall box
(available from Extron) for most mounting options, but you can
use the included mounting brackets (mud rings) instead.
Before using the mud rings, verify that the installation
conforms to national and local electrical codes.
CAUTION Extron provides one mud ring with each MKP
control panel. However, you may choose to use a
wall box. Because the tolerances on electrical boxes
are very loose, Extron recommends that you
measure the actual box that you plan to use before
making any precise cuts.
The electrical box must be at least 2.5" (7 cm) deep to
accommodate the MKP’s rear enclosure.
Install the mud ring or wall box as follows:
1 . If you are using a mud ring , use the template that came
with the mud ring. Cut out the indicated center portion.
To meet the UL listing requirements, the MKP must be
installed in a wall box.
If you are using a wall box , refer to the cutout template in
appendix A that corresponds to the faceplate you are
using; and cut out the center portion of it as indicated on
the template.
2 . Place the wall box or mud ring against the installation
surface or measure the cut according to the template, and
mark the guidelines for the opening on the wall or
furniture.
3 . Cut out the wall or furniture material from the marked
area.
4 . Check the size of the opening by inserting the wall box,
mud ring, or control panel into it. The box or mud ring (if
used) and/or control panel should fit easily into the
opening. Enlarge or smooth the edges of the opening if
needed.
5 . If you are using a wall box , feed cables through the wall
box punch-out holes, and secure them with cable clamps
to provide strain relief.
6 . Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink (figure 2-2).
To prevent short circuits, you can cut back the outer
foil shield to the point where the cable exits the cable
clamp. Both braided and foil shields should be
connected to an equipment ground at the other end
of the cable.

7 . If you are using a mud ring , follow the directions, if any,
that came with the mud ring to attach the clips that fasten
it to the wall or furniture (figure 2-3).
To meet the UL listing requirements, the MKP device
must
be installed in a wall box.
