ELECTRICAL INSTALLATION
1. General
This section gives electrical installation procedures, power distribution, and interconnect
information for each component on the T
3
CAS system.
2. Equipment and Materials
Refer to the applicable Outline and Installation Diagram in the MECHANICAL INSTALLATION
section for mating connector part numbers.
3. Electrical Installation Procedure
The information necessary to provide the electrical interconnections is contained in the following
paragraphs. Refer to Section 4, LOADING/GRADIENT SPECIFICATIONS, for a list of the signal
names used in the interconnect diagrams and tables.
NOTE:
Unless otherwise specified, all wires shall be stranded #22 AWG.
NOTE:
All ARINC 429 data bus wires shall be stranded #22 AWG twisted shield wire. All outer
shields shall be terminated to the airframe ground. Unshielded portions of the cable
and shield ground wires should be kept to a minimum length to minimize RF
susceptibility.
NOTE:
All electrical installations must be in compliance with SFAR-88.

CAS Computer Units
Figure 3-1 shows some general types of T
3
CAS system installations, using various
combinations of controllers (control panels) and transponders.
The various installation options require different electrical connections as described in the
paragraphs that follow.
The T
3
CAS Computer Unit uses programming and configuration straps to select or
deselect various TCAS, TAWS and transponder functions. In addition, the T
3
CAS may
use the APM and ASDB to select or deselect various TAWS/RWS functions.
The T
3
CAS Computer Unit ARINC 600 connector layout is shown in Figure 3-2. The
contact arrangement for the various connector plugs are shown in Figure 3-3 thru Figure
3-8. Figure 3-9 shows the connector pin layout for the DATA LOADER connector located
on the front of the computer unit.
