MKP 2000 • Installation 7
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.
If you are using a wall box , refer to the cutout template in Reference Information
(see page 45) 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 (see figure 4).
ATTENTION:
•
To prevent short circuits, 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.
• Afin d’éviter les court circuits, réduisez le blindage en aluminium extérieur
jusqu’à ce que le câble sorte de la cosse de câble. Le blindage tressé et le
blindage en aluminium devraient être connectés à la masse d’un équipement à
l’autre bout du câble.
