3 INSTALLATION
PROCEDURE
3.1 Unpacking
Unit
Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred
during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the
original shipping container and all packing materials. Do not return the unit to Garmin until the carrier
has authorized the claim.
Retain the original shipping containers for storage. If the original containers are not available, a separate
cardboard container should be prepared that is large enough to accommodate sufficient packing material
to prevent movement of the item within the container.
3.2 Wiring Harness Installation
Allow adequate space for installation of cables, connectors, and strain relief as necessary. The installer
shall supply and fabricate all of the cables. All wiring must be in accordance with FAA AC 43.13-1B.
All electrical connections are made through a 44-pin D subminiature connector. Section 4 defines the
electrical characteristics of all input and output signals. Required connectors and associated hardware are
supplied with the connector kit.
See Appendix C for examples of interconnect wiring diagrams. Construct the actual harnesses in
accordance with aircraft manufacturer authorized interconnect standards.
