2.4 Cabling & Wiring
Refer to the interconnect examples in Appendix C for wire gauge guidance.
In some cases, a larger gauge wire such as AWG #18 or #20 may be needed for power connections. If
using AWG #18 barrel contacts, ensure that no two contacts are mounted directly adjacent to each other.
This minimizes the risk of contacts touching and shorting to adjacent pins and to ground.
Use wire and cable meeting the applicable aviation regulation. When routing wire and cable, observe the
following precautions:
•
Keep wire and cable as short and as direct as possible
•
Avoid sharp bends
•
Avoid routing near power sources (e.g. 400 Hz generators, trim motors, etc) or near power for
fluorescent lighting
2.5 Cooling Air
The GMA 350/350H does not have provisions for attaching cooling air and does not generate an excessive
amount of heat during typical operations, however the thermal characteristics of the installation should
always be assessed. An undesirable thermal condition could be created due to the unit's own internal power
dissipation combined with restricted ventilation, or due to heat generated by adjacent equipment. Limiting
thermal build up, by means of fan or natural convection is always a good practice and recommended to
increase the product life.
