8.0 Mounting C/D Unit
8.1
After all wire connections have been made and screws
tightened, pull excess cable back through the rear of the
C/D Unit so that cable does not stick up through the front
of the board.
8.2
Place the C/D Unit in the cutout hole and align the four
mounting holes in the plastic housing so they line up with
the four mounting clips installed earlier.
8.3
With the four #6 x 1-1/4” Flat head sheet metal screws
provided (P/N 2520-1001), use a Phillips head screwdriver
to insert the screw through the plastic housing, through
the hole in the short side of the C/D Unit mounting clips,
through the drywall and into the small hole on the long
side of the mounting clip. The sheet metal screw will
thread through the small hole and tighten the C/D Unit
enclosure to the wall. Repeat this procedure with the other
three screw’s positions.
8.4
When all four screws have been installed, the C/D Unit
should be securely fastened to the wall. Line up the front
cover bezel assembly with the enclosure, making sure that
the hinge posts line up with the slots that they insert into.
Press the assembly gently onto the enclosure. You will hear
and feel it snap into place if it has been aligned correctly.
9.0 Wiring Control
Cable to Relay Unit
9.1
Run cable through an unused knockout at the bottom
of Relay Unit and secure with cable clamp. Leave approxi-
mately 6” to 12” of control cable in the Relay Unit for a
service loop.
Note:
Control cable must
not
run through the circuit
breaker panel. Conduit may be required for the control
cable.
9.2
Strip back the outer jacket of the control cable about
4 inches.
