INSTALLATION GUIDE
With the Trig units fixed in place, run the harness along its
intended routing. Make sure that this routing will not cause any
chafing of the cables and will not interfere with any of the aircraft
controls or any other systems.
Try to avoid routing the wiring near any antenna cables,
especially the transponder or any wiring associated with high
power or pulsing devices (alternator, strobe light, etc). If you
must cross these cables, try to do so at an angle of 90 degrees.
Once in position, secure the wiring to the aircraft structure using
aviation approved ties or string.
Terminate the ground connections on a suitable grounding point
using a crimp or screw terminal. Terminate the power supply
connections via the correct rated circuit breaker as specified in
the installation manual.
Any unused connections must be either trimmed or tied back and
any exposed wire covered with suitable insulating tape or
terminated to prevent shorts.
For radio wiring, ensure that the sockets for the microphone and
headphones are electrically isolated from the panel using bushes
or washers.
Connect the D Type connections to the units, hand tightening the
securing screws.
