Fuses and circuit protection
There are 3 levels of power protection in the autopilot system. The drive (motor) and associated
cables are initially protected by the current sensing and stall condition detection within the ACU
hardware and software. A second level of protection is provided to these parts and the ACU
components by the ACU's internal power fuse. Protection for the entire autopilot system and its
wiring back to the main power distribution panel is provided by your vessel’s circuit breaker / fuse.
