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
DONGLE. VERIFY THE WIRING AGAINST THE WIRING DIAGRAM AND PERFORM A
CONTINUITY CHECK TO CONFIRM GOOD CONNECTIONS AND PROPER PIN
LOCATIONS.
(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” at the Dongle and the ELT receptable to divert moisture from the
connections. See “List of Acronyms, Abbreviations, and Definitions” on page 15.
(e) All grounds must be common to aircraft ground.
(2) Minimum 24 AWG wire size for 24-bit address reprogramming ground wires.
(3) The Dongle is provided with a preassembled wiring harness (P/N 611-4010).
(4) If the Dongle is being installed with the ELT, refer to the ELT installation and operation
manual and coordinate the wiring installation.
(5) Refer to applicable ELT abbreviated component maintenance manual for Metal or composite
airframe installations.
