Installation, cont’d
When the image is displayed correctly
Once the system has been cabled and tested, the interface can be installed in the wall or furniture. To mount the interface and install optional MAAP devices (CIA111 only), see the next section, "Mounting the Interfaces".
CThe CIA111 and CIA114 interfaces must be 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.

Mounting the Interfaces
This section describes how to mount the interfaces. Follow the instructions that are appropriate to your interface.
CInstallation and service must be performed by authorized personnel only.
Mounting the CIA111 or CIA114
The CIA111 mounts to a wall or podium using a
NThe CIA114 requires a minimum of 3.0” H x 2.0” W x 2.5” D space inside 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, "Reference |
| Information", as a guide to measure and mark the hole in |
| the wall or furniture for installing the wall box. |
CThe
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 |
| 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. |
WTo 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.
