Procedure for Modifying and Installing Communication Cables
The following procedure explains how to modify and install a Woodhead 9-pin D-Sub
connector (MA9D00-32).
Follow the steps described below to modify communication cables and connect them to the
connector.
CAUTION
Be careful not to injure your hands or fingers on any sharp blades or tools used
to modify the cable.
Use appropriate blades and/or other tools to modify the cable. Using
inappropriate blades and/or other tools may result in bodily injury and/or
equipment damage.
(1) Strip approx. 47.5 mm of the cable covering with extra
care so that you do not scratch on braided shield
underneath.
Do not strip the cable covering more than necessary.
Excess stripping may cause short-circuit and/or make
the cable more sensitive to noise.

back the shield over the cable covering. Cut off the
shield at approx. 10 mm from the stripped side of the
cable covering.

(4) Insert the signal wires into the terminal block on the connector and secure the signal
wires. Carefully connect the same signal wire to the same terminal on both ends.
To prevent faulty wiring, make a rule of connection. For instance, connect the green
signal wire to the A1/A2 terminal and the red signal wire to the B1/B2 terminal.
