Chapter 3: Installation 25
Signal connections
Make the necessary connections to your ST60+ instrument (see the
Connection to
ST60+ Tridata instrument
illustration).
Power supply connections
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.
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.
