Vehicle 12-80VDC 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 10 Amp 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.
Caution:
!
For installation by trained service personnel only.
Warning:
!
Risk of ignition or explosion. Explosive gas mixture may be vented from
battery. Work only in well ventilated area. Avoid creating arcs and sparks at
battery terminals.
