NOTE:
Terminal pins may be removed from the plug using Molex extraction tool 11030002, or
equivalent.
b)
Insert the remote switch power wire female pin into Pin 3 of the plug.
c)
Insert the remote switch ground wire into Pin 9 of the plug.
E.
Wiring Installation
1)
Route the remote switch harness wire bundle and breakout wiring through the airframe.
2)
Route the antenna coax cable through the airframe.
NOTE:
A longer coax cable, up to 20 feet (6.1 m), may be fabricated if the cable provided is too
short. Use RG-142 or RG-400 coax cable.
3)
Support the wiring and coax cable by clamping or other suitable means, such that the wiring is properly
supported and protected from chaffing and strain. Refer to the aircraft manufacturer’s written
instructions or as described in AC 43.13-1, Chapter 11, § 9 through 12, as applicable.
F.
Antenna Connection
1)
Connect the coax cable to the antenna, making sure the cable is routed and supported such that there
is no tensile load (i.e., strain) on the connection.
G.
Cockpit Remote Switch Power Connection
1)
Connect the remote switch power wire directly to battery power using a 1-amp in-line fuse or circuit
breaker.
NOTE:
If the wire is spliced, fabricate the splice in a manner acceptable to the aircraft
manufacturer or as described in AC 43.13-1, § 13.
NOTE:
This power source provides energy for the remote switch assembly LED, but has no
effect on switch functions, as the switch will control the ELT with or without power.
H.
ELT Power Connection
1)
Connect the ELT power wire to a +28 VDC source controlled by the avionics switch or master switch
using a 1-amp, in-line, slo-blo fuse or circuit breaker.
NOTE:
If the wire is spliced, fabricate the splice in a manner acceptable to the aircraft
manufacturer or as described in AC 43.13-1, § 13.
NOTE:
This power source provides energy for the ELT navigation functions.
I.
Airframe Ground Connections
1)
Connect the following grounds to the airframe in accordance with the aircraft manufacturer’s written
instructions or as described in AC 43.13-1, Chapter 11, § 15. See Figure 21 Remote Switch Harness
Wiring Diagram on page 54.
a)
Harness ELT plug ground from Pin 11.
b)
Harness ELT plug strain relief ground.
c)
Harness remote switch plug ground from Pin 9.
d)
ARINC 429 twisted pair shield ground.
