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.

.
If you are using a wall box
, feed the cables through the
wall box punch-out holes, and secure them with cable
clamps to provide strain relief.

.
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, 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.

If you are using a mud ring

that came with the mud ring to attach the clips that fasten
it to the wall or furniture (figure 2-3).
To meet UL listing requirements, the MKP
must
be
installed in a wall box.

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. Cut-out
templates that show the cutout requirement for the circuitry
enclosure on the rear of the control panel are provided in
appendix A of this manual.
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, the user 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:

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 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.

.
Use the template (or place the wall box or mud ring
against the installation surface), and mark the guidelines
for the opening on the wall or furniture.
