6) INSTALLATION
Origo™ Arc are a three-phase welding rectifier, to be connected across three input phases. The mains
cable is connected to the circuit breaker. The primary terminal is reconnectable for different input voltages
(220, 380 or 440 V - 60Hz). The electrical diagram 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.
