may be connected to the
BDU by use of the pigtail that is supplied with the system.
By use of this pigtail, you may extend the cable length as long as you keep the
total source impedance < 250 m
Ω
and cable inductance < 5

H.
The BDU is equipped with an internal 10 A thermal circuit breaker, therefore
no external fuse is necessary in order to protect the BDU. However, in order to
avoid short circuit in the power cable/connector, the ships DC outlet should be
protected by a 10-15 A fuse or circuit breaker. If the automatic circuit breaker
pops out check the power supply polarisation.
