ELECTRICAL CONNECTIONS
WARNING
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
GROUNDING
The frame of the welder must be grounded. A
ground terminal marked with the symbol 
is located inside the reconnect/input access door for this purpose. See your local and national electrical codes for proper grounding methods. Refer to the Technical Specifications at the beginning of this chapter for proper cable sizes.
HIGH FREQUENCY INTERFERENCE PROTECTION
If possible, locate the Power Wave away from radio controlled machinery. The normal operation of the Power Wave may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.
INPUT FUSE AND SUPPLY WIRE CONSIDERATIONS
Refer to the Technical Specifications at the begin- ning of this Installation section for recommended fuse and wire sizes. Fuse the input circuit with the recom- mended super lag fuse or delay type breakers (also called “inverse time” or “thermal/magnetic” circuit breakers). Choose an input and grounding wire size according to local or national electrical codes. Using fuses or circuit breakers smaller than recommended may result in “nuisance”
INPUT VOLTAGE RECONNECT
PROCEDURE
WARNING
Turn main input power to the machine OFF before performing reconnect procedure. Failure to do so will result in damage to the machine. DO NOT switch the reconnect bar with machine power ON.
Welders are shipped connected for the highest input voltage listed on the rating plate. To connect to a dif- ferent input voltage, refer to reconnect instructions located on the inside of the input access door or in Figure A.2. If the main reconnect switch is placed in the wrong position, the welder will not produce output power. If the Auxiliary (“A”) lead is placed in the wrong position, there are two possible 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 (“A”) 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, prop- erly connect the “A” lead, reset the breakers, and try again.
