Power
The unit is designed to be powered by a 12 or 24 V DC system. It is protected against reverse polarity, under voltage, and over-voltage (for a limited duration). A fuse or circuit breaker should be fitted to the positive supply. For recommended fuse rating refer to the technical specifications. The shield (A) can in most cases be insulated from all other wires. If interference is encountered from other onboard electronics, the shield can be connected to a vessel hull ground to help reduce any interference, but it is not generally required. The yellow wire (B) in the power cable is not to be used and should be insulated from all other wires.
