Fuse Requirements
WARNING - For proper and safe installation, the input power cable must be connected to a fused circuit on the
vehicle. If the supply connection is made directly to the battery, the fuse should be installed in the positive lead
within 5 inches (12.7 cm) of the battery's positive (+) terminal. Use VM3055FUSEKIT to install this fuse or use
equivalent 20A fast blow fuse.
Note: For North America, a UL Listed fuse is to be used.

Power Cable Identification
