12-2. Grounding Generator To Truck Or Trailer Frame

1

GND/PE2

3

Electrically bond generator frame to vehicle frame by metal-to-metal contact.

YBed liners, shipping skids, and some running gear insulate the welding generator from the ve- hicle frame. Always connect a ground wire from the generator equipment grounding terminal to bare metal on the vehicle frame as shown.

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

1Equipment Grounding Terminal (On Front Panel)

2Grounding Cable (Not Supplied)

3Metal Vehicle Frame

Connect cable from equipment ground terminal to metal vehicle frame. Use #10 AWG or larger insulated copper wire.

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