1. Install the backboard. Refer to the instructions in
Mounting the backboard, earlier in this chapter.
2. Attach the spacer adaptor, if required, by following the
instructions enclosed with the kit.

Installing a terminal in non-recessed furniture
If required, mount the backboard according to the
instructions in Mounting the backboard, covered earlier in
this chapter. Refer to Figure 2-2. Check the lines as
described in Testing the line to the terminal. Then
continue:
A. Positioning the terminal on the backboard
1. Prepare the inside service wires (ISW) by cutting off the
exposed ends and wrapping them with electrical tape.
The tape ensures that the bare wires will not touch the
internal components when you insert the wires into the
terminal.
Observe normal electrical wiring precautions when
handling the wires.
2. Feed the wires through the access hole in the back­
board.
3. Insert three security studs in the threaded holes in the
back of the mounting plate of the terminal rear housing.
4. Line up the ISW with the oval 25 mm by 12.5 mm (1 in.
by 1/2 in.) wiring access hole in the housing assembly
of the terminal, as you move the terminal towards the
backboard.
