10.Mount a circuit breaker (not included) as near to the auxiliary battery as possible, but
away from engine or exhaust heat (See
“Recommended Wire Size/Circuit Breaker”
Chart for proper size). Connect one end of a new wire of the proper size to the “2”
terminal of the Isolator. Run the wire to the circuit breaker and connect it to the “AUX”
terminal or its equivalent. Run another wire from the circuit breaker to the auxiliary
battery, connecting one end to the “BAT” terminal of the circuit breaker and the other
to the positive (+) terminal of the auxiliary battery. Repeat for three and four battery
isolators. (See Figure D.)

properly grounded with a conventional ground strap. Protect with circuit breakers as
needed. (See Figure E.)
