The circuit breaker is a safety device designed to protect the battery cables from high over-current faults.

1. The circuit breaker must be mounted on the positive (red) cable between the GP-MPPT-40 charge controller and the batteries. (See Figure 4-N)

NOTE:
The circuit breaker should be mounted as close to the batteries as possible. Go Power! recommends using the 2 ft. positive (red) cable between the circuit breaker and the battery bank.

2. Using 3 of #10 x 3/4” screws included, securely mount the circuit breaker. (See Figure 4-O).

3. Assemble the ring lugs of the positive (red) cables to the circuit breaker. (See Figure 4-P).

4. Tighten the nuts holding the ring lugs to 75 in. lbs.

5. Connect the bare end of the 8 ft. positive (red) cable to the GP-MPPT-40 charge controller. Cut excess cable length as required. Follow the GP-MPPT-40 User Manual for additional details and recommended torque and strip lengths.

6. Connect the bare end of the 10 ft. negative (black) cable to the GP-MPPT-40 charge controller. Cut excess cable length as required. Follow the GP-MPPT-40 User Manual for additional details and recommended torque and strip lengths.

7. Use the included tie-wraps to secure the cables together.

NOTE:

• This helps reduces the amount of electronic noise radiated by the kit.
• Ensure these paired cables run through the same hole(s) as they are routed.

8. Use the 3/8” white cable clamps to secure the cable to the RV.
