Installing the AC Power Cord
Step 1
– locate the cut end of the power cord and strip off the outer
black PVC insulation approximately 7 1/2” from this cut end.
Step 2
– With the three wires (white, green and black)
exposed, trim the white wire to a length of 5”, the green wire to
4” and leave the black wire at 7 1/2” length.
Step 3
– Wrap the strain relief around the black PVC jacket of
the power cord approximately 1” from where the stripped
jacket begins. Note alignment of the strain relief (photo 6.12a).
Step 4
– With a pair of slip joint pliers, firmly squeeze the
strain relief around the power cord. Grasp the strain relief and
feed the stripped end of the power cord wires into the
corresponding hole in the chassis.
Step 5
– While still grasping the strain relief with the pliers,
guide the strain relief into the chassis hole. By firmly pressing the compressed strain relief into
the hole, the strain relief should slide into place (photo 6.12b).

When installing the indicator lamp, be certain that no part of C6 on the electronics assembly
touches any part of the lamp holder. This may require repositioning C6 on the board.
CAUTION
The nut that secures the lamp assembly can be firmly tightened by placing the point of a
center punch on one of the corners of the nut. Firmly tap the center punch to tighten the nut.

The black PVC jacket of the power cord is thin and very easily cut. Be very careful not to cut
so deep as to accidentally cut the insulation of the inside wires.

There is a specific tool that makes installing strain reliefs simple. If you find yourself installing
strain reliefs on a regular basis, this tool is worth owning. See TubeDepot.com p/n TL-R-29
