INPUT WIRE AND FUSE SIZE

Fuse the input circuit with the super lag fuse recom- mended in the Technical Specifications at the begin- ning of this section or use delay type1 circuit breakers. Choose an input and grounding wire size according to local or national codes; also see the Technical Specifications. Using fuses or circuit breakers smaller than recommended may result in "nuisance" shut-offs from welder inrush currents, even if you are not weld- ing at high output currents.

1Also called "inverse time" or "thermal/magnetic" circuit breakers. These circuit breakers trip faster as the magnetude of the fault cur- rent increases.

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. Install the reconnect panel jumper links (see Figure A.3) for the proper input volt- age. See the connection diagram located on the inside cover of the access panel cover.
