Note: Pin 1 arrow is bottom right!  Arrow should be visible
if cable is inserted correctly.

Strip a couple of inches of the CAT-5 outer sleeve.

Untwist the pairs and press them into the slots indicated.

Install the clamping bar to hold the wires in place.

Clip off both ends of the ground connection between pins 39(A)
and 36(E) adjacent to the connector body.  Clip loose ends
off each wire adjacent to the connector body, leaving intact
the jumper between 36(E) and 34(H).

Add a handle, if available, to the strain relief.  Fold the
wires around the top of the connector body and install the
the strain relief (with handle, if available) over them.

Install ferrules on the wires at the other end of the cable.

Attach the ferrules to the current loop as indicated in the
instructions for the current loop device..
