INPUT AND GROUND CONNECTIONS

MACHINE GROUNDING

The frame of the welder must be grounded. A ground terminal marked with the symbol shown is located inside the reconnect / input access door for this pur- pose. See your local and national electrical codes for proper grounding methods.

INPUT CONNECTION

WARNING

ELECTRIC SHOCK can kill.

•Only a qualified electrician should connect the input leads to the Power Wave. Connections should be made in accordance with all local and National Electrical Codes and the connection dia- gram located on the inside of the reconnect / input access door of the machine. Failure to do so may result in bodily injury or death.

-----------------------------------------------------------------------

Use a three-phase supply line. A 1.75 inch (45 mm) diameter access hole for the input supply is located on the case back. Connect L1, L2, L3 and ground according to the Input Supply Connection Diagram.

INPUT FUSE AND SUPPLY WIRE

CONSIDERATIONS

Refer to Specifications page for recommended fuse and wire sizes. Fuse the input circuit with the recommended super lag fuse or delay type breakers (also called "inverse time" or "thermal/magnetic" circuit breakers). Choose input and grounding wire size according to local or national elec- trical codes. Using fuses or circuit breakers smaller than recommended may result in "nuisance" shut-offs from welder inrush currents, even if the machine is not being used at high currents.

INPUT VOLTAGE SELECTION

Welders are shipped connected for the highest input voltage listed on the rating plate. To move this connection to a dif- ferent input voltage, see the diagram located on the inside of the input access door, or the Reconnect Diagram K2344- 1 and K2344-2 shown below. If the Auxiliary lead (indicated as ‘A’) is placed in the wrong position, there are two possi- ble results. If the lead is placed in a position higher than the applied line voltage, the welder may not come on at all. If the Auxiliary lead is placed in a position lower than the applied line voltage, the welder will not come on, and the two circuit breakers in the reconnect area will open. If this occurs, turn off the input voltage, properly connect the aux- iliary lead, reset the breakers, and try again.
