Power supply connections

SeaTalk systems

CAUTION:

When instruments are connected to SeaTalk, ensure that the power supply for the SeaTalk 12 V line is protected by a 5 A fuse.

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	No. of instruments	Power connections

Up to 10 m	13 maximum	1
	26 maximum	2

Up to 20 m	7 maximum	1
	13 maximum	2
