2.8.2 Mechanical Installation
NOTE
Avoid installing the unit near heat sources. If this is not possible, insure that additional
cooling is provided. Allow adequate space for installation of cables and connectors. The
installer will supply and fabricate all of the cables. All wiring must be in accordance with
FAA Advisory Circulars AC 43.13-1B and AC 43.13-2B.
1. Assemble the connector/rack kit according to
the dimensions given in
brackets are not supplied due to the wide range of mounting configurations available. Suitable
mounting brackets may be fabricated from sheet metal or angle stock. To insure a sturdy mount,
rear support for the unit must be provided.
2. Looking at the bottom of the transponder, make sure the front lobe of the locking mechanism is in
a vertical position. This can be accomplished by using a 3/32" hex wrench through the face plate.
3. Slide the unit into the rack until the front lobe of the unit touches the rack.
4. Turn the hex wrench clockwise until unit is secured in the rack. Continue turning until tight. Do
not over-tighten the screw.
5. To remove the unit from the rack, turn the 3/32" hex wrench counterclockwise until it disengages
from the rack.
