Vehicle 12-80 VDC Power Connection
Caution:
For proper and safe installation, the input power cable must be connected to a fused circuit on the vehicle. This
fused circuit requires a tenAmp maximum time delay (slow blow) high interrupting rating fuse. 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 positive (+) terminal. Note: For North America, a UL Listed fuse is to be used.
Caution:
For installation by trained service personnel only.
Note: Please see Power Adapter Cable for information on adapting a VX1, VX2 or VX4 DC power supply to the VX6.
