A.
General Considerations and Recommendations
CAUTION:
IF GROUND OR OTHER CONNECTIONS ARE BROKEN OR OTHERWISE DAMAGED, THE
ELT IS STILL CAPABLE OF AUTOMATIC ACTIVATION; HOWEVER, THE COCKPIT REMOTE
SWITCH MAY BE INCAPABLE OF RESETTING THE ELT AND OPERATION MAY NOT BE
INDICATED ON THE REMOTE SWITCH LED.
CAUTION:
INCORRECT TERMINATION OF THE WIRING IN THE CONNECTORS MAY DAMAGE THE
ELT, CAUSE TRANSMISSION ISSUES, OR RESULT IN A NON-FUNCTIONING REMOTE
SWITCH. VERIFY THE WIRING AGAINST THE WIRING DIAGRAM AND PERFORM A
CONTINUITY CHECK TO CONFIRM GOOD CONNECTIONS AND PROPER PIN LOCATIONS.
CAUTION:
TO PREVENT INADVERTENT ELT ACTIVATION OR POSSIBLE COMPONENT DAMAGE, DO
NOT CONNECT THE HARNESS TO THE ELT OR COCKPIT REMOTE SWITCH UNTIL ALL
POWER AND GROUND WIRING CONNECTIONS ARE COMPLETED.
1)
The following wiring and grounding considerations and recommendations are applicable:
a)
Minimum 22 AWG wire size.
b)
Shielding is recommended to help prevent EMI and RF interference.
c)
Use high quality conductor meeting MIL-W-16878, M22759, M27500, or a commercial equivalent
acceptable for use in aircraft applications.
d)
Provide a “Drip Loop” in the remote switch harness connection to the ELT to divert moisture from the
connector. See TASK 25-62-10-990-805 on page 13 for a definition.
e)
Provide a “Service Loop” in the remote switch harness connection to t
he remote switch assembly, such
that the assembly can be withdrawn from the panel far enough to easily disconnect the harness plug.
See TASK 25-62-10-990-805 on page 13 for a definition.
f)
ELT and remote switch grounds must be common to aircraft ground.
