Lead 42 connects to GROUND stud on front of unit.

Jumper 42 is connected to 90 at factory.

Supplementary Protector CB7 pro- tects single-phase receptacle RC5 and the load wires from overload. If CB7 opens, all generator output stops and the receptacle does not work.

Three-Phase Generator Power ! Stop engine.

! Power and weld outputs are live at the same time. Discon- nect or insulate unused cables.

.Have qualified person install ac- cording to circuit diagram and Generator Power Guidelines (see Section 12).

Remove plug before inserting leads. Reinstall bushing.
