19.1) Requirements on circuit wiring
■ CAUTION: The connections have to be completed by the aircraft manufacturer
in accordance to effective certification and wiring diagram (Fig. 69).
The electromagnetic compatibility (EMC) and electromagnetic inter-
ference (EMI) is greatly affected by the wiring and has to be checked
for each installation. Refer to section 19.1.1.
▲ WARNING: The supply to the various consumers (e.g. battery) has to be
protected adequately by fuses (consult wiring diagram). Using fuses
too large may result in damage to electric equipment.
Under no circumstances route consumers cables (e.g. battery) side
by side with ignition cable. Induction could cause problems.
■ CAUTION: An excess-voltage protection has to be realized by the aircraft
manufacturer in accordance to effective regulations.
▲ WARNING: The certification to the latest requirements such as FAR or EASA has
to be conducted by the aircraft manufacturer.
▲ WARNING: Do not bend, kink, pinch or otherwise improperly stress the wiring
harness. Use proper routing, clamping and strain relief on wiring
harnesses.
19.1.1) Electromagnetic compatibility (EMC)
The engine complies with the requirements of EMI and lighting protection as
per standard RT CA DO-160C, sections 18, 20-22 and IEC 801-2.
The following EMC/EMI tests were performed:
- Radio frequency Susceptibility (conducted)
- Radio frequency Susceptibility (radiated)
- Audio Frequency Susceptibility
- Lightning Susceptibility
- Conducted RF Interference
- Radiated RF Interference
