Northstar strongly recommends as a good safety practice that the unit be
connected to an external circuit breaker or 3-amp fuse located near the
battery or breaker box. The internal fuse is designed to protect the unit

and prevent electrical fires. The power wiring should be connected
directly to the battery when possible for optimum noise immunity.
