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 25-62-11-990-805 on page 13 for a definition.
e)
Provide a “Service Loop” in the remote switch harness connection to the remote switch assembly,
such that the assembly can be withdrawn from the panel far enough to easily disconnect the
harness plug. See TASK 25-62-11-990-805 on page 13 for a definition.
f)
ELT and remote switch grounds must be common to aircraft ground.
