11-2. Grounding Generator To Truck Or Trailer Frame

! Always ground generator frame to vehicle frame to pre- vent electric shock and static electricity hazards.

! Also see AWS Safety & Health Fact Sheet No. 29, Grounding of Portable And Vehicle Mounted Welding Generators.

Bed liners, shipping skids, and some running gear insu- late the welding generator from the vehicle frame. Al- ways connect a ground wire from the generator equip- ment grounding terminal to bare metal on the vehicle frame as shown.

! If unit does not have GFCI re- ceptacles, use GFCI-pro- tected extension cord.
