19.1) Requirements on circuit wiring
■ ATTENTION: The connections have to be completed by the aircraft builder in
accordance to effective certification and wiring diagram (ill. 52).
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 chapter 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.
■ ATTENTION: An excess-voltage protection has to be realized by the aircraft
builder in accordance to effective regulations.
▲ WARNING: The certification to the latest requirements such as FAR or JAR has
to be conducted by the aircraft builder.
