2.3 Equipment Installation Procedures
2.3.1 Cooling Requirements
Forced air-cooling of the PMA8000C is not required. However, the units should be kept away from heat
producing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without ade-
quate cooling air provided.
2.3.2 Mounting Requirements
The PMA8000C must be rigidly mounted to the instrument panel of the aircraft structure, within view and
reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2B, or other
FAA-approved aircraft technical data. The unit may be mounted in any area where adequate clearance for
the unit and associated wiring bundle exist.
To prevent noise, avoid installing the unit close to high current devices or systems with high-voltage pulse
type outputs, such as DME or transponders. Avoid running the interconnecting bundles near any high cur-
rent wires.
2.3.3 Audio Panel Mounting Rack Installation
Remove the unit from the mounting tray by unscrewing the 3/32" hex-head screw that is in the center of the
unit. Use caution to avoid hitting the photo-detector lens. Carefully slide the unit free of the tray. Set the
unit aside in a safe location until needed. Install the tray using six clip nuts (475-630-0002), and six FHP 6-
