a) Strip the outside insulation of the AC cable approx. 10cm (3.94 inches). Trim the
wires so that the ground wire is 10mm (0.4 inches) longer than the other wires. Strip
14mm (0.55 inches) at the end of each of the wires.
b) Unscrew the base of the strain relief from the helix-shaped body. Insert the base
through the outside opening in the AC input cover and screw the locknut securely
(11-14 Lb-inch.) the base, from the inside.
c) Slide the helix-shaped body onto the AC cable. Insert the stripped wires through the
strain relief base until the outer cable jacket is flush with the edge of the base.
Tighten (16-18 Lb-inch.) the body to the base while holding the cable in place. Now
the cable is securely fastened inside the strain relief. Refer to Fig. 3-2.
