Power

The unit is designed to be powered by 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 on board 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 is not to be used and should be insulated from all other wires.
