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.
