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.
7. Insert the wall box into the opening, and attach it to the
wall, stud, or furniture with nails or screws, leaving the
front edge flush with the outer wall or furniture surface.
See the illustration below.
If attaching the wall box to wood, use four #8 or #10
screws or 10-penny nails. A minimum of 1/2 inch
(1.3 cm) of screw threads must penetrate the wood.
If attaching the wall box to metal studs or furniture, use
four #8 or #10 self-tapping sheet metal screws or machine
bolts with matching nuts.

8. Cable and test the wallplate before fastening it into the
wall box. The cables will be inaccessible after installation.

Preparing the Site and Installing the Wall Box
Choose a location that will allow cable runs without inter-
ference. Allow enough depth for both the wall box and the
cables. The box should be at least 2.5” (6.4 cm) deep to
accommodate the circuit board, connectors, and cables. You
may need to install the cables into the wall, furniture, or
conduits before installing the wallplate. The wallplate can be
installed in a one-gang electrical wall box. Underwriters
Laboratories (UL) Listed wall boxes are recommended.
The installation must conform to national and local electrical
codes and to the wallplate’s size requirements. Dimensional
drawings and an actual-size cut-out template are provided in
the appendix of this manual.
1. Cut out the center portion of the cut-out template that
corresponds to the type of installation being used (full-sized
wall box, compact wall box, or no wall box).
2. Place the template (or the wall box) against the installation
surface, and mark the guidelines for the opening on the
wall or furniture.
3. Cut out the material from the marked area.
4. Check the opening size by inserting the wall box into the
opening. The box and the wallplate’s circuit board should
fit easily into the opening. Enlarge or smooth the edges of
the opening if needed.
5. 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.

The Extron Wallplates are wall- or furniture-mountable
accessories that provide a convenient way to make pass-through
connections from audio and video source devices.
The wallplates can be directly mounted onto or in furniture or
walls, or they can be attached to mounting brackets (mud rings)
or standard electrical wall boxes.
• WP 120, WP 130, WP 150, WP 170, and WP 180 fit into a
standard U.S. one-gang wall box.
• WP 120 AUS, WP 150 AUS, and WP 170 AUS fit into a
standard Australian wall box.
CAUTION Installation and service must be performed by
authorized personnel only. These units must be
installed with accordance with the National
Electrical Code and with local electrical codes.
