CAUTION
For battery powered vehicles:
• Twist the red and red/white wires together and connect to battery positive.
• Black and black/white wires must be connected to battery negative. Twist these wires together and
connect to battery negative.
• Green wire must be connected to the vehicle chassis ground.
For internal combustion engine powered vehicles:
• Twist the red and red/white wires together and connect to battery positive.
• Twist the black wire and a black/white together and connect to battery negative.
• Green wire is connected to the vehicle chassis ground, which can also be battery negative.
WARNING
For proper and safe installation, the input power cable must be connected to a fused circuit on the ve-
hicle. If the supply connection is made directly to the battery, the fuse should be installed in the positive
lead within 5 inches of the battery's positive (+) terminal. Use VM3055FUSE (or equivalent) to install
the fuse as shown below:
• For 12VDC input, use the 10A fuse from the kit or a slow blow fuse that has a DC voltage rating
greater than 12VDC.
• For 24VDC input, use the 6A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 24VDC.
• For 36VDC input, use the 4A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 36VDC.
• For 48VDC input, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage rating greater
than 48VDC.
Note: For North America, a UL Listed fuse is to be used.
