Cable Bundle Termination on Backshell Assembly

CAUTION
Do not put the concave side of the strain relief clamp across the cable bundle. Placing the
concave side of the strain relief clamp across the cable bundle will damage the cable
bundle.
Terminate the cables to the backshell assembly after all shielded cables are prepared in accordance with
section 4.3.7.
1. Terminate the crimped cable bundle contacts in the D-sub connector using the interconnect
diagrams in appendix B for the correct connections and pinouts.
2. Make sure the pin is engaged into the connector by gently tugging on the wire.
3. For the GTX 3X5 units, install the configuration module wires into the connector.
◦ Refer to section 4.4 for configuration module installation instructions.
4. Wrap the cable bundle with silicone fusion tape at the point where the backshell strain relief and
cast housing will contact the cable bundle.
5. Place the smooth side of the backshell strain relief clamp across the cable bundle. Secure using
three 4-40 x 0.375" pan head screws.
6. Terminate the ring terminals to the tapped holes on the backshell by placing ring terminal on the
8-32 x 0.312" pan head shield terminal screw in this order before finally inserting the screw into
the tapped holes on the shield block:
a. Split washer
b. Flat washer
c. First ring terminal
d. Second ring terminal (if needed)
