A.4 Cable Assembly Steps
Use a utility knife to remove 12mm of the outer jacket of the cable and use diagonal cutters
to remove any shielding as shown in Figure A-1. Carefully remove 2-3mm of insulation from
the wires using a wire stripper. Avoid nicking the center conductor as you strip the insulation
from the wire. Ensure that the drain wire is at the same length as the other wires.
WARNING : make sure DC power is not connected during cable
assembly
