Attaching the wall box to wall studs
To attach the wall box to wood, use four #8 to # 10
wood or sheet metal screws. A minimum of 1/2 inch
(1.25 cm) of screw threads must penetrate the wood.
If the wood is a 2 x 4, such as a wall stud, 10-penny or
larger nails can be used.
To attach the electrical wall box to metal, use four #8
or #10 sheet metal screws (self-tapping) or #8 or #10
machine bolts with matching nuts.
7. Output cables will usually be out of sight inside a
wall, for example. Feed the cables through the wall
box “punch-out” holes for connection to the interface.
Cable clamps should be used to hold the cables in
place for strain relief.
8. Exposed cable shields (braids or foil) are potential
sources of short circuits. Trim back and/or insulate
shields with heat shrink. Details for typical maximum
coaxial cable bend inside a wall box are given on
page 2-3.
9. Configure, cable and test the interface before securing
the interface to the wall box. Configuration consists of
setting circuit board DIP switches and jumpers based
on installation requirements. See page 2-14 for more
information.

Preparing the installation site and
installing the wall box
Actual-size rough-in templates for each model are provided
in Appendix B. If needed, make a 100% size photocopy of
the appropriate template to use for installation. Compare
the photocopy with the faceplate and wall box to make sure
the photocopy size is the same as the equipment.
Use the template as a guide to mark and cut the hole in the
wall or furniture through which the interface will be installed.
The innermost line represents the opening where material
will be removed and the wall box will be installed.
1. Cut out the center portion (up to the guidelines) of the
cut-out (rough-in) template.
2. Place the template on the surface where the interface
will be installed. Use a soft pencil to mark the
guidelines for the opening on the wall/furniture.
3. Cut out the material from the cut-out area with a
jigsaw or small hand saw.
4. Check the opening size by inserting the wall box (if
used) or the interface (if no wall box is used) into the
opening. The wall box will be mounted flush with the
outer wall or furniture surface. The box and/or
interface should fit easily into the opening.
5. If needed, use a saw, file or sandpaper to enlarge the
hole. Smooth the edges of the opening to avoid
damage or injury to yourself or the cables during
installation.
6. Attach the wall box to the wall stud (2 x 4) with nails
or screws, leaving the front edge flush with the wall
surface, as shown in the following illustration.
