Installation instructions
General information
This section contains information for installing and wiring the Northstar
M3 GPS, antenna, and interfaces.
All installation procedures should follow acceptable practices, methods,
and techniques as described in Advisory Circulars (AC) 43.13-1A and
43.13-2A.
Special installation
requirements
•
Before inserting or removing the M3 from the mounting tray, turn off
power to the tray using the avionics master switch or circuit breaker,
even if the unit’s power switch is turned off. This will prevent inrush
current from arcing across the power connector.
•
Use only a GPS antenna specified within this manual.
Only the
Northstar AN120, AN135, and AN155 antennas are approved for use
with the M3. Consult the factory for special applications not covered
in these instructions.
•
The GPS antenna must be mounted on the top of the aircraft.
•
The GPS antenna should be located at least two feet away from any
other antennas and from the vertical stabilizer and canopy.
•
Forced air cooling must be supplied to the unit for all installations.
•
Electrical noise suppression of existing equipment may be required to
obtain satisfactory performance.
