Remote Mounting the Keyboard
Display Module (Fig. 17)
1. The Keyboard Display Module can be mounted
either on the face of a panel door or other remote
locations.
NOTE: A DATA CONTROLBUS MODULE™ or an Exten-
sion Cable Assembly is required to connect
RM7888A to a remote Keyboard Display Module.
2. When mounting the Keyboard Display Module on
the face of the door panel, closely follow these
instructions:
a. Select the location on the door panel for flush
mounting. Pay attention to the insertion dimen-
sion of the two Keyboard Display Module screws,
two interlocking ears and the two plug-in con-
nectors to allow for sufficient clearance (1/4 in.
[6 mm] minimum) inward from the surface of the
door panel.
b. Mark the two screw locations, two interlocking
ear locations and the two plug-in connector
locations. Drill the pilot holes for the mounting
screws. Provide for two holes on the door panel
for the interlocking ears and two holes for the
plug-in connectors.
c. Mount the Keyboard Display Module on the door
using two no. 4 screws.
3. When mounting the Keyboard Display Module on a
wall or remote location, use part number 203765,
Remote Mounting Bracket.
a. Using the Remote Mounting Bracket as a tem-
plate, mark the four screw locations and drill the
pilot holes.
b. Mount the Remote Mounting Bracket using four
no. 6 screws.
c. Mount the Keyboard Display Module by aligning
the two interlocking ears with the two mating
slots on the Remote Mounting Bracket.
d. Insert the two interlocking ears into the two mat-
ing slots. Push on lower corners of the Keyboard
Display Module to secure it to the Remote
Mounting Bracket. e. Make sure the Keyboard
Display Module is firmly in place.

2. Align the amplifier circuit board edge connector with
the keyed receptacle on the RM7888A. Make sure
the amplifier nameplate faces away from the Relay
Module.
3. Push in the amplifier until the circuit board is fully
inserted into the receptacle and then push the
amplifier toward the RM7888A retaining clasp.
4. Make sure the amplifier is firmly in place.
