INPUT CONNECTION

WARNING

Only a qualified electrician should connect the input leads to the POWER WAVE® R350. Connections should be made in accordance with all local and national electrical

codes and the connection diagrams. Failure to do so may result in bodily injury or death.

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

A 10 ft. (3.1m) power cord is provided and wired into the machine. Follow the power cord connection instructions.

For Single Phase Input

Connect green lead to ground per National Electrical Code.

Connect black and white leads to power.

Wrap red lead with tape to provide 600V insulation.

For Three Phase Input

Connect green lead to ground per National Electric Code.

Connect black, red and white leads to power.

INPUT FUSE AND SUPPLY WIRE CONSIDERATIONS

Refer to Specification Section for recommended fuse, wire sizes and type of the copper wires. 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 electrical codes. Using input wire sizes, fuses or cir- cuit 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

The POWER WAVE® R350 automatically adjusts to work with different input voltages. No reconnect switches settings are required.

WARNING

The POWER WAVE® R350 ON/OFF switch is not intended as a service disconnect for this equipment. Only

aqualified electrician should con- nect the input leads to the POWER WAVE® R350. Connections should be made in accordance with all local and national electrical codes and the con- nection diagram located on the inside of the reconnect access door of the machine. Failure to do so may result in bodily injury or death.
