4.For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and 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 wire(s) around the exposed foil twice. Cut off the excess wire.

e.Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires.

f.Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing.
