4-core machines

220 V - 240 V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)

The machine can be connected to power supplies with a single phase of 220-240 V. In this case, the Black cable 

must be joined to the Red cable, and then connected to the phase in the permanent electrical installation. The 

White/Black cable must be connected to the neutral wire. The Green cable must be connected to the earth.

400 V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)

The machine can be connected to power supplies with three phases and a neutral wire of 400 V. In this case, the 

Black cable must be connected to one of the three phases, the Red cable to the same, and the White/Black cable 

to the neutral wire. The Green cable must be connected to the earth.

400 V TWO PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)

The machine can be connected to power supplies with three phases and a neutral wire of 400 V. In this case, the 

Black cable must be connected to one of the three phases, the Red cable to a different phase, and the White/Black 

cable to the neutral wire. The Green cable must be connected to the earth.

110 V SINGLE PHASE WITH NEUTRAL WIRE (1-2 GROUP MACHINES)

IMPORTANT: 

The machines manufactured for use with electrical voltages of 

110 V have been manufactured with electrical elements specifically for that 

voltage. They can thus only be installed at a voltage of 110 V, as indicated on 

the specific electrical diagram for these voltages.

The machine can be connected to power supplies with a single phase of 110 V. In this case, the Black cable must 

be connected to the permanent electrical installation phase, the Red cable must be connected to the same phase 

as the Black cable, and the Black/White cable to the neutral wire. The Green cable must be connected to the earth.
