6.6 Installation
Considerations
6.6.1 Cable Location Considerations
Use cable meeting the applicable aviation regulation for the interconnect wiring. Any cable meeting
specifications is acceptable for the installation. When routing cables, observe the following precautions:
•
All cable routing should be kept as short and as direct as possible.
•
Avoid sharp bends.
•
Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near
power for fluorescent lighting.
