3.4 Wiring
Requirements
3.4.1 Introduction
The installing agency shall supply and fabricate all external cables
and mating connectors. The length and routing of external cables
should be carefully studied and planned before attempting
installation of the equipment. Allow adequate space for installation
of cable and connectors. Avoid sharp bends and placing cables
near aircraft control cables. Maintain a minimum clearance of three
(3) inches from any control cable. If wiring is run parallel to
combustible fluid or oxygen lines, maintain a separation of six (6)
inches between the lines.
3.4.2 Power Wires
Audio International recommends that the chassis be electrically
bonded to the airframe structure by a conductive mounting point
with <0.1
Ω
resistance using <50
Ω
impedance cable. Aluminum
wool, nylon webbing impregnated with aluminum oxide abrasive or
fiber bristle brushes are the approved tools for removing anodized
surfaces at mounting point where the bonding wire is attached.
Power and Ground wires shall be in accordance with
MIL-W-22759
or equivalent. Protect power wires with circuit breakers or fuses
located close to the electrical power source bus.
3.4.3 Video Lines
Composite video connections shall be shielded coaxial cable in
accordance with
M17/94-RG179
or equivalent. Cable shields shall
be grounded at the source. Use of individual wires rather than
proper coaxial cable connections through production breaks is
unacceptable, and will cause significant and detrimental noise
introduction to the video signal supplied to the LCD-9151-201-x.
Serial digital video connections are recommended to use shielded
coaxial cable in accordance with
PIC V76261
or equivalent.
