Installation Procedures
2.5.4
C
ABLING AND
Wiring should be installed in accordance with AC 43.13-1B Chapter 11. For dual CNX80 installations,
care should be taken to ensure separation between wires of redundant systems to reduce the possibility of
loss of navigation due to a single event. When wire separation cannot be achieved, the following issues
should be addressed:
It should not be possible for a cable harness to be exposed to wire chafing in a manner that both
GPS units fail simultaneously;
The cable harness should not be located near flight control cables and controls, high electrical
capacity lines or fuel lines;
The cable harness should be located in a protected area of the aircraft (e.g., isolated from engine
rotor burst); and
Do not route cable near high-energy sources
Refer to the Electrical Connections in Appendix D for the appropriate wiring connections to assemble the
wiring connector. Once the cable assemblies have been made, attach the cable connectors to the rear
connector plate. After installing the mounting tube, attach the assembled connector. Route the wiring
bundle as appropriate. Use 22 to 24 AWG wire for all connections except for power. Use 20 AWG for
power/ground. Avoid sharp bends.
