Mounting the Interfaces
This section describes how to mount the interfaces. Follow the
instructions that are appropriate to your interface.
Installation and service must be performed by
CAUTION
authorized personnel only.
Mounting the CIA111 or CIA114
The CIA111 mounts to a wall or podium using a two-gang wall
box. The CIA114 mounts in a one-gang wall box. The
installation must conform to national and local electrical codes
and to the equipment's size requirements.
The CIA114 requires a minimum of 3.0" H x 2.0" W
x 2.5" D space inside the wallbox.
The CIA111 and CIA114 interfaces must be
CAUTION
installed into Underwriters Laboratories (UL)
approved electrical wall boxes. See the following
section on UL requirements. The wall boxes are
not included with the interfaces; the installer is
responsible for obtaining and installing the boxes.
UL Requirements
The following Underwriters Laboratories (UL) requirements
listed pertain to the installation of the CIA111 and CIA114
interfaces into a wall or furniture.
1.
These units are not to be used beyond their rated voltage
range.
These units must be installed in UL listed junction boxes.
2.
3.
These units must be installed with conduit in accordance
with the National Electrical Code.
Preparing the site and installing the wall box
1.
Choose an installation location that will allow 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
interface.
2.
Use the appropriate template in Appendix A as a guide to
measure and mark the hole in the wall or furniture for
installing the wall box.
The cut-out templates are not to scale and are
CAUTION
provided for reference only. Measure the hole
carefully before cutting.

3.
Check the opening size by inserting the wall box into the
opening. The box should fit easily into the opening.
Enlarge or smooth the edges of the opening, if necessary.
4.
Feed cables through the wall box punch-out holes, and
secure them with cable clamps to provide strain relief.
5.
Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink, if needed.
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.
Insert the wall box into the opening, and attach it to the
6.
wall stud/furniture with nails or screws, leaving the front
edge flush with the outer wall or furniture surface
(figure 2-6).

Figure 2-6 — Attaching the wall box to a wall stud
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 the 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.
