7.0 Wiring the Control

Cable to Control/

Display Unit

7.1

Remove cover from C/D unit by pulling the cover outward

first on one side and then the other.  Be extremely careful

not to damage the hinge posts which protrude out approxi-

mately 1/2" on each side of the lower front of the unit.

7.2

Pass the four wires of the control cable through the
square hole in the rear of the enclosure and through the
3/8" diameter hole in the printed circuit board (PCB).
Strip approximately 1/2" off of each wire end.

7.3

The control cable consists of four #18 AWG Conduc-
tors.  These are typically black, white, green and red.
To insure proper operation and noise immunity, do not
run these wires parallel to or next to high voltage (Class
I) circuits.  Connect the wires as shown in Table 1 and
in Figure 5.
