2.3.2 Mounting Requirements
The PMA6000B must be rigidly mounted to the instrument panel of the aircraft structure and within view
and reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2B.
The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle
exist.
2.3.3 Mounting Rack Installation
Remove the unit from the mounting tray unscrewing the 3/32-inch hex-head screw that is in the center of
the unit. The hex-head screw is the lower opening. Carefully slide the unit free of the tray. Set the unit
aside in a safe location until needed. Install the tray using six FHP 6-32 x ½-inch screws, P/N 475-632-
0012 and #6-32 clip nut, P/N 475-630-0002. The audio selector panel must be supported at front and rear
of the mounting tray.
2.3.4 Audio Panel Tray and Connector Assembly
The rack connectors mate with two 44-pin connectors in the PMA5000EX. The connectors are a sub-
miniature crimp-type, and require the use a hand crimp tool, from table below (or equiv.). The connectors
are mounted to the tray back plate with #4-40 screws (475-440-1038), from the inside of the tray and the
mounting block, 431-891-0100. Ensure that proper strain relief and chafing precautions are made during
wiring and installation, using the cable clamp (625-001-0002).
Two grounding lugs are provided, which may be attached to the rear mounting plate with 2 ea #4-40 x ¼”
screws with captivated lock washers. These provide a convenient location to connect the shield ground
terminations.

2.4 Cable Harness Wiring
Refer to Appendix C for assembling the wiring harness as required for the installation. All wires must be
MIL-SPEC in accordance with current regulations. Two- and three-conductor with shield wire must be
used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and
soldering technique must be used at all times. It is imperative that correct wire be used.
Refer to FAA Advisory Circular 43.13-2B for more information. Failure to use correct techniques may
result in improper operation, electrical noise or unit failure. Damage caused by improper installation will
void the PS Engineering warranty.
