are a three-phase welding rectifier, to be connected across three input phases. The mains cable
is connected to the circuit breaker. The primary connections are reconnectable for different input voltages
(220, 380 or 440 V - 60Hz or 380 V -50 Hz). The picture 6.3 shows the different voltage connections
procedures. Remove the cover on the left panel and reconnect the terminal block as shown on the electric
diagram.
Recommended cable areas and fuses ratings are listed below.
Connected the rectifier across three input phases and ground connection according to regulations.
