Preparing the Installation Site

Take the following steps to prepare the installation site:

1. Determine the electronics, AAPs, and cabling required for this installation.
The Ackermann CRX 4090/CRX 4120 floor box can accommodate four AKM
UK faceplates.

2. Turn off all equipment. Make sure the computer, interface, and output devices
(e.g., projector, monitor, etc.) are all turned off and disconnected from the
power source.

3. Select an installation site that allows cable runs without interference. Allow
enough depth for both the floor box and the cables.

4. Install the floor box in accordance with the documentation that accompanied
the floor box.

5. Route all cables required for the installation through the floor box punch-out
holes.

CAUTION

Exposed cable shields (braids or foil) are potential sources of short circuits.
To prevent short circuits, shields should be trimmed back or insulated with
heat shrink. Both braided and foil shields should be connected to an
equipment ground at the other end of the cable.

Assembling and Pretesting the Faceplates

The faceplates and optional AAPs must be installed, cabled, and pretested before
the faceplates are mounted into the floor box.

1. Unpack the AKM UK faceplates and AAPs.

• Each faceplate has two screws: a small (#4-40 x 5/16" Phillips pan head)
machine screw and a larger (#6-32 x 1/2" Phillips pan head) self-tapping
screw. Save these screws for the “Mounting Faceplates in the Floor Box”
procedure.

• Each AAP has four #4-40 nuts and captive washers used to secure the
AAP to a faceplate. These nuts will be used in step 2 of this procedure.

2. Attach AAPs to the faceplates.

a. Insert the mounted screws on the back of the AAP through holes on the

faceplate.

b. Secure the AAP to the faceplate using the #4-40 nuts and captive washers

provided with the AAP.

c. Repeat this step until all AAPs have been installed.

3. Set the gain and any switches on the the interface and other devices built into

or attached to the faceplates. Refer to the RGB 400xi Series User’s Manual (part
number 68-542-01), the Extender Series User’s Manual (part number 68-552-01),
or the appropriate manual for the devices being installed.

4. Connect cables to each faceplate.

a. Orient each faceplate for proper insertion into the floor box. The faceplate

flange with the large hole must be oriented toward the side of the floor
box with the smaller (self-tapping) screw holes. (Refer also to the
installation figure on the next page.)

b. Connect video, audio, and power cables to each device as explained in

the documentation that accompanied the device.

5. Connect all output device, interface, and computer power cords and then turn
on all devices.

All devices should have power, and the audio and video should be working
properly. If not, check all cabling and switch settings, and make adjustments
as necessary.
