1. Insertion/extraction tools from ITT Cannon are all plastic; others are plastic with metal tip.
2. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject
to change without notice.
3. Alternate contacts for 18 AWG wire: As an alternative to the Positronic contacts listed (and
provided in the installation kit), the installer may use contacts made by ITT Cannon under P/N
031-1007-001. These contacts require the use of a different crimp tool positioner than shown
in the table, with the part numbers as follows: Daniels P/N K250, Astro P/N 616245, or ITT
Cannon P/N 980-0005-722.
4. For the card-edge connector pin contacts, use AMP part number 90272-1 or equivalent
crimping tool.

RACK INSTALLATION

1. The back plate of the rack may optionally be removed for ease of mounting in the aircraft
panel. To do so, remove the two #4-40 screws, tilt the back plate away from the tray, and then
slide the back plate to the side.
2. Figures 3-3, 3-4 and 3-5, starting on pages 3-11, 3-13, and 3-15, show outline dimensions for
the aviation rack for the various 400 Series units. Install the rack in a rectangular 6.320" x
2.700" hole (or gap between units) in the instrument panel (refer to Figure 3-9, page 3-23).
The lower-front lip of the rack should be flush with, or extend slightly beyond, the finished
aircraft panel.
If the front lip of the mounting rack is behind the surface of the aircraft panel,
the 400 Series unit connectors may not fully engage.
Make sure that no screw heads or other obstructions prevent the unit from fully engaging in the
rack (refer to the "Connector Engagement Test," section 5.3.1, page 5-15). Exercise caution
when installing the rack into the instrument panel. The rack is designed to facilitate removal of
the 400 Series for use in Demo Mode outside the aircraft. Deformation of the rack may make it
difficult to install and remove the 400 Series unit.
3. Install the rack in the aircraft panel using six #6-32 flat head screws and six self-locking nuts.
The screws are inserted from the inside through the holes in the sides of the rack.
4. If the back plate was previously removed (see step #1), replace the back plate by positioning
the tabs on the back plate in the slots of the left side of the rack (viewing it from the cockpit)
and attaching it by replacing the two #4-40 screws.
