6.1 Cabling and Wiring General Instructions
CAUTION
ENSURE THERE ARE NO WIRING ERRORS BEFORE CONNECTING THE CABLES. INCORRECT WIRING
COULD DAMAGE COMPONENTS.
NOTE
Shield terminations to the GDL connector backshell must be less than 3.0". Shield terminations for
interfaced equipment should be as short as practical. Wiring must be shielded as required in
section 10.
Install wire in accordance with AC 43.13-1B chapter 11. Allow adequate space for installation of cables and
connectors. For connector and tooling information, refer to
section 3. The installer supplies and fabricates all cables
according to information in this manual. Cable lengths will vary depending on installation. Ground and shield
terminations of interfaced equipment can vary. For more information, refer to the equipment manufacturer’s
installation manual. The following considerations should also be addressed.
• Cable harness should not be located near controls/control cables, high voltage, electrical noise sources, or fuel
lines
• Cable harness should be in a protected area of the aircraft (e.g., isolated from engine rotor burst)
• Use wire gauge specified in section 10
• Route and secure the wire bundle as appropriate
• Avoid sharp bends and chafing
• Pigtail lengths must be less than 3.0 inches
