1 Equipment Grounding Terminal (On
Front Panel)
2 Grounding Cable (Not Supplied)
3 Metal Vehicle Frame
Connect cable from equipment ground
terminal to metal vehicle frame. Use #8
AWG or larger insulated copper wire.
Electrically bond generator frame to ve-
hicle frame by metal-to-metal contact.
! Bed liners, shipping skids, and
some running gear insulate the
welder/generator from the vehicle
frame. Always connect a ground
wire from the generator equipment
grounding terminal to bare metal on
the vehicle frame as shown.
! Use GFCI protection when operat-
ing auxiliary equipment. If unit does
not have GFCI receptacles, use
GFCI-protected extension cord. Do
not use GFCI receptacles to power
life support equipment.
