1.6 Mounting

Refer to Section 2 through Section 6 for specific mounting instructions for each component of the G3X,
and to Appendix A for Outline & Installation Drawings.

1.7 Wiring/Cabling Considerations

Use MIL-W-22759/16 (or other approved wire) AWG #24 or larger wire for all connections unless
otherwise specified. The supplied standard pin contacts are compatible with up to AWG #22 wire. In
cases where some installations have more than one LRU sharing a common circuit breaker, sizing and
wire gauge is based on aircraft circuit breaker layout, length of wiring, current draw on units, and internal
unit protection characteristics. Do not attempt to combine more than one unit on the same circuit breaker.
RG400 or RG142 coaxial cable with 50 Ω nominal impedance and meeting applicable aviation
regulations should be used for the installation.
