CAUTION
For battery powered vehicles:
GND must be connected to the vehicle chassis ground.
For internal combustion engine powered vehicles:
GND 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 vehicle.
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. The fused circuit requires a maximum time delay (slow blow)
fuse with a current rating as noted below.
• For 60VDC input, use a 6A slow blow fuse that has a DC voltage rating greater than 60VDC.
• For 72VDC input, use a 6A slow blow fuse that has a DC voltage rating greater than 72VDC.
• For 96VDC input, use a 4A slow blow fuse that has a DC voltage rating greater than 96VDC.
• For 108VDC input, use a 4A slow blow fuse that has a DC voltage rating greater than 108VDC.
• For 120VDC input, use a 4A slow blow fuse that has a DC voltage rating greater than 120VDC.
• For 132VDC input, use a 3A slow blow fuse that has a DC voltage rating greater than 132VDC.
• For 144VDC input, use a 3A slow blow fuse that has a DC voltage rating greater than 144VDC.
Note: For North America, a UL Listed fuse is to be used.
