5. Pull the auxiliary cable armor down to cover the cable and cable gland area. Wrap the auxiliary
cable armor with self-fusing electrical tape (non-adhesive) to press the flexible auxiliary cable
armor against the cable and cable gland. Overwrap the self-fusing tape with vinyl adhesive
electrical tape to protect the area. The purpose of wrapping tape over the auxiliary cable armor is
to provide pressure to improve its sealing function. An alternative method can also be followed
using adhesive shrink tubing instead of self-fusing tape and vinyl electrical tape.
NOTE: The tightening torque for the front housing screws should be 9 – 13 lb-in, and the tightening
torque for the top housing screws should be 17 – 22 lb-in. Do not over-tighten.
Strain Relief Installation when using cable with molded in strain relief
cables
Remove the insulation from the steel strain relief cables as shown. Install the strain relief collars with set
screws. Thread the strain relief wires through the key ring in the top of the pendants and back through the
strain relief collars. Tighten the set screws until the strain relief cables are secure. Trim off the strain relief
wires so they are flush with the collars. Tie-wrap the insulated strain relief cables to the main cable to
prevent them from peeling away from the main cable.

Strain Relief Installation when using non-strain relief round cable
A loop of cable is made in no-strain relief pendant cable by tie-wrapping the cable in a 12 inch minimum
loop; this requires at least 38” of extra cable. Mount a cable grip and strain relief bracket to the opening of
the pendant festoon junction box. Use thimbles to protect the strain relief wire from abrasion by the
bracket. Fasten the strain relief cables to the bracket, one on each side. Bring the strain relief cables to
meet the round pendant cable below the cable loop. Tie-wrap the cables to the round cable below the
loop and then tie-wrap them again above the pendant’s cable gland. Run the strain relief wires through
the key ring in the top of the pendant and secure them with the strain relief collars, tightening the set
screws securely.
