Have a qualified electrician connect the input power leads to the L1, L2, and L3 terminals of the input con- tactor. Follow all national and local electrical codes. Use a three-phase line. Refer to the connection dia- gram located on the inside cover of the access panel cover. Also see Figure A.3.

INPUT WIRE AND FUSE SIZE

Fuse the input circuit with the super lag fuses recom- mended on the Technical Specifications page or use delay type circuit breakers. Choose an input and grounding wire size according to local or national codes; also see the Technical Specifications page. Using fuses or circuit breakers smaller than recom- mended may result in “nuisance” shut-offs from welder inrush currents, even if you are not welding at high currents.
