Remote Mounting of Keyboard
Display Module.
1.
The Keyboard Display Module can be mounted
either on the face of a panel door or on other remote
locations; see Fig. 18.
2.
When mounting the Keyboard Display Module on
the face of a door panel, closely follow these instruc-
tions:
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 inch
minimum inward from the surface of the door
panel.
b. Use the Keyboard Display Module as a template;
see Fig. 50. Mark the two screw locations, two
interlocking ear locations and two plug-in con-
nector locations. Drill the pilot holes for the
mounting screws. Provide for two holes on the
door panel for the interlocking ears and plug-in
connector holes.
c. Mount the Keyboard Display Module securing
the two no. 4 screws.
