3.3.2 Electrical Connections
1. The installer must take the following into consideration before installation.
• Use of any wire or cable not meeting specification voids all warranties.
• The installer is responsible for supplying wires, cables and connectors.
• Wire-marking identification is at the discretion of the installer. GPS and L-band antenna
cables should be clearly marked as both connections may use similar connectors.
• All wiring must be in accordance with industry-accepted methods, techniques, and
practices.
• Refer to paragraph 3.3.3 for details on shielded wire preparation.
• The length and routing of the external cables must be carefully studied and planned
before attempting installation of the equipment.
• The wiring harness should not run adjacent to heaters, engine exhaust, and heat
sources or be located near fuel lines, high electrical capacity lines, flight control cables,
and protected areas of the aircraft or be exposed to wire chafing.
• Avoid sharp bends while routing the cables.
• Cable runs should be as short as practical. Terminate shields in the backshell of the
mating connector, P1.
• Power wires are 20 AWG and Signal wires are 22 AWG. Use MIL-Spec 22759/34 (Spec
55) or equivalent wire for installation.
• Installer is responsible for determining appropriate aviation circuit breakers needed to
protect aircraft wiring. Manufacturer recommends the following:
•
3.0 amp circuit breaker for the installations with 14 VDC input.
•
2.0 amp circuit breaker for the installations with 28 VDC input.
