Power supply connections

CAUTION: Protect the power supply

Ensure that the 12 V power supply for the instrument is
protected by a suitably rated fuse or protective circuit breaker.
SeaTalk systems
Ensure that the power supply for the SeaTalk bus is protected by a 5 A fuse or
circuit breaker.
Systems with a large number of instruments on the SeaTalk bus may require
connections to the power supply from each end of the system ('ring-main' style),
to maintain sufficient voltage throughout the system.
This requirement depends on the total length of the cable run and the total
number of instruments in the system, as follows:
Cable run
Up to 10 m
Up to 20 m
5 A fused,
12 V dc supply
(typically provided
by autopilot)
SeaTalk power connections
Stand alone instruments
Stand-alone instruments are not connected to SeaTalk and therefore need to be
connected to an alternative 12 V power source. Power cables are available in 2 m
and 9 m lengths.
