Use 16mm cables for the input from the vehicle main battery and cables to the auxiliary battery.
Install a 40A in-line fuse close to the main battery on the positive cable (
Fig 2).
Install a second 40A fuse close to the auxiliary battery on the positive cable.
Make sure all connections are secure and terminated correctly with appropriate tools.
The input cables must be terminated with a RED 50A coupler matching the input on the DC Distribution
Box marked "MAIN BATT".
If solar panels are used, they can be connected to the input marked "SOLAR PANEL" and must have a
maximum voltage below 42V.
Install the fuse on the positive cable
close to the main battery.
Ensure terminals are crimped securely.
