ELECTROMAGNETIC COMPATIBILITY (EMC)

The EMC classification of the POWER WAVE® i400 is Industrial, Scientific and Medical (ISM) group 2, class A. The POWER WAVE® i400 is for industrial use only. (See prints L10093-1, -2 Safety Pages in the front of Instruction Manual for further details).

Locate the POWER WAVE® i400 away from radio con- trolled machinery. The normal operation of the POWER WAVE® i400 may adversely affect the operation of RF con- trolled equipment, which may result in bodily injury or dam- age to the equipment.

INPUT AND GROUNDING 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 purpose. See your local and national electrical codes for proper grounding methods.

INPUT CONNECTIONS

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 con- nection diagram 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) diame- ter access hole for the input supply is located on the case back. Connect L1, L2, L3 and ground according to the input supply and ground connection decals located near the input power terminal block (1TB) and ground block inside of the rear input reconnect box.

Input Fuse and Supply Wire Considerations

Refer to Specification in Installation Section for recommend- ed 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 "ther- mal/magnetic" circuit breakers).

Choose input and grounding wire size according to local or national electrical codes. Using input wire sizes, 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.

Power Supply Connection for the Fanuc R30iA Controller

The POWER WAVE® i400 is equipped with a dedicated robot power terminal block (4TB) specifically designed to feed input power directly to the Fanuc R30iA controller through the power source rotary ON/OFF switch. The K2677-1 Integration kit provides the proper cable and instal- lations instructions to make this connection.

WARNING

The POWER WAVE® i400 on/off switch is not intended as a service disconnect for this equipment. Only a qual- ified 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 diagram located on the inside of the reconnect access door of the machine. Failure to do so may result in bodily injury or death.

Do not attempt to back feed input power though the robot power terminal block (4TB) into the POWER WAVE® i400. This is not its intended purpose and may result in machine damage, bodily injury or death.
