5. Installation
5.1 Unpacking and Inspecting Equipment
Carefully unpack the GPS receiver and make a visual inspection of the unit for
evidence of any damage incurred during shipment. If the unit is damaged,
notify the shipping company to file a claim for the damage. To justify your
claim, save the original shipping container and all packaging materials.
5.2 GPS Receiver Mounting
The TN72 TABS GPS Receiver is designed to be mounted in any convenient
location in the cockpit, the cabin, or an avionics bay.
The following installation procedure should be followed, remembering to allow
adequate space for installation of cables and connectors.
•
Select a position in the aircraft that is not too close to any high
external heat source. (The TN72 is not a significant heat source itself
and does not need to be kept away from other devices for this reason).
•
Avoid sharp bends and placing the cables too near to the aircraft
control cables.
•
Secure the unit to the aircraft using four screws and locking nuts.
Rivets can alternatively be used. The GPS receiver should be
mounted to a flat surface.
5.3 Cooling Requirements
The TN72 TABS GPS Receiver meets all applicable TSO requirements without
forced air-cooling.
Attention should however be given to the incorporation of cooling provisions to
limit the maximum operating temperature if the TN72 is installed in close
proximity to other avionics. The reliability of equipment operating in close
proximity in an avionics bay can be degraded if adequate cooling is not
provided.
