WIRING AND HARNESSING (CONTINUED)

elimination of the problem may be very expensive or impossible (eg.
if there is simply not enough space to provide ground plane or
antenna separation as recommended).  Or, the aircraft strobe noise is
audible but not objectionable, etc.  These problems should be
discussed early and thoroughly with the customer.

SUMMARY

The paragraphs above are not intended to be highly technical, completely thorough, or
extensive, but serve as a reminder for certain precautionary or follow-up procedures
for general avionics installations.  Trimble is prepared to assist at any point with
additional information, hints, or literature.  Simply call 1-800-487-4662 and ask for
technical assistance.

INSTALLATION

Installation of any equipment in an aircraft requires that the work be performed by a
Certificated Radio Repair Station with appropriate ratings.  The installing agency must
complete an FAA Form 337 and compute a new weight and balance for the aircraft for
insertion in the Aircraft Flight Manual.  Unless the mechanic is the designated inspector for a
Certificated Radio Repair Station or holds an Inspection Authorization, the work is subject to
inspection and approval of an FAA inspector or the holder of an Inspection Authorization.

The following items and suggestions should be considered prior to installation of your Terra by
Trimble TN 200D Navigational Receiver.

1.

Discuss the location of this receiver with your customer, preferably in a position that
provides ease of operation.

2.

Avoid installing the TN 200D near heat sources.  If unavoidable, insure additional
cooling is provided.

3.

Insure that adequate clearance exists behind the panel for sleeve, connectors, and
additional cooling if required.  A minimum of 14.00" (35.56 cm) is recommended.

4.

Refer to Terra by Trimble TN 200D Outline Drawings for panel cut-out details and
mounting dimensions as well as pertinent notes.

5.

Install the sleeve assembly in the instrument panel.  Insure compliance with standards
set forth in the FAA Aircraft Inspection and Repair Document AC 43.13-2A.

Note:
Insure that the sleeve is installed with the large opening toward the top.

6.

The 15 pin “D” connector assembly supplied  with the Terra by Trimble TN 200D
must be wired correctly to the aircraft avionics systems or severe damage may result
to the Terra by Trimble TN 200D or other systems.  The interconnecting wiring for
the 15 pin “D” connector is shown in Figure 3-6 (without glideslope) and Figure 3-7
(with glideslope).  Comply with standards set forth in FAA Aircraft Inspection and
Repair Document AC 43.13-1A Section 7 and other pertinent FAR’s as required.
Insure MIL-SPEC wire is utilized for all interconnects.
