Preparing the site, installing the 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. An actual-size
cut-out template that shows the cutout requirement for the
circuitry enclosure on the rear of the control panel is provided in
appendix A of this manual.
Installation using a UL listed wall box (available from Extron) is
recommended for most mounting options, but the included
mud rings can be used 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, the user may choose to
use a wall box. Because the tolerances on electrical
boxes are very loose, it is recommended 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:
1a . 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, this device must be
installed in a wall box.
1b . If you are using a wall box , cut out or make a 100% size
photocopy of the cut-out 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 template (or the wall box or mud ring) against
the installation surface, and mark the guidelines for the
opening on the wall or furniture.
3 . Cut out the wall/furniture material from the marked area.
4 . Check the opening size by inserting the wall box, mud
ring, or control panel into the opening. 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).

Figure 2-2 — Grounding outer braided and foil
shields
To prevent short circuits, the outer foil shield can be
cut back 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.
