6. For connection at the core processor housing, prepare shielded cable as follows (for
armored cable, omit steps d, e, f, g):
a. Strip 4 1/2 inches (114 mm) of cable jacket.
b. Remove the clear wrap that is inside the cable jacket, and remove the filler material
between the wires.
c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm)
of foil or braid and drain wires exposed, and separate the wires.
d. Wrap the shield drain wires around the exposed foil twice. See Figure 3-6. Cut off
the excess wire.

e. Place the shielded heat shrink over the exposed shield drain wires. The tubing
should completely cover the drain wires.
f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing. See
Figure 3-7.
