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.
3.2

Wiring Harness Installation

Allow adequate space for installation of cables and connectors. The installer shall supply and fabricate all
cables. All electrical connections to the GTX 32 are made through one 25-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 the aircraft manufacturer authorized interconnect standards.
Check wiring connections for errors before inserting the GTX 32 into the rack. Incorrect
wiring could cause internal component damage.
