5. Installation
This section provides detailed installation and interconnect instructions for the
TMA44 Audio Panel.
Please read this manual carefully before beginning any installation to prevent
damage and post installation problems. Installation of this equipment requires
special tools and knowledge.
5.1 Unpacking and Preliminary Inspection
Use care when unpacking the equipment. Inspect the units and parts supplied
for visible signs of shipping damage. Examine the unit for loose or broken
buttons, bent knobs, etc. Verify the correct quantity of components supplied
with the list in Section 4. If any claim is to be made, save the shipping material
and contact the freight carrier. Do NOT return units damaged in shipping to
Trig. If the unit or accessories shows any sign of external shipping damage,
contact Trig to arrange for a replacement. Under no circumstances attempt to
install a damaged unit in an aircraft. Equipment returned to Trig for any other
reason should be shipped in the original Trig packaging, or other UPS
approved packaging.
5.2 Equipment Installation Procedures
5.2.1
Cooling Requirements
Forced-air cooling of the TMA44 is not required. However, the unit should be
kept away from heat producing sources such as defrost or heater ducts,
dropping resistors or heat producing avionics without adequate cooling air
provided.
If the TMA44 is installed in a 28 VDC aircraft system, a 15
, 15 watt
dropping resistor (p/n 701-015-1501) should be installed. Failure to do so will
generate unnecessary heat inside the unit and may void Trig's warranty.
