4-core machines
220V-240V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)
The machine can be connected to power supplies with a single phase of 220-240V. In this case, the Black cable
must be joined to the Brown cable, and then connected to the phase within the permanent electrical installation.
The Blue or Grey cable must be connected to the neutral wire. The Green/Yellow cable must be connected to the
earth.

400V 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 400V. In this case, the
Black cable must be connected to one of the three phases, the Brown cable to the same, and the Blue or Grey cable
to the neutral wire. The Green/Yellow cable must be connected to the earth.

400V 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 400V. In this case, the
Black cable must be connected to one of the three phases, the Brown cable to a diff erent phase, and the Blue or
Grey cable to the neutral wire. The Green/Yellow cable must be connected to the earth.

110V SINGLE PHASE WITH NEUTRAL WIRE (1-2 GROUP MACHINES)
IMPORTANT:
The machines manufactured for use at electrical voltages of 110V
have been manufactured with electrical elements specifi cally for that voltage.
They can thus only be installed at a voltage of 110V, as indicated on the specifi c
electrical diagram for these voltages.
The machine can be connected to power supplies with a single phase of 110V. In this case, the Black cable must be
connected to the permanent electrical installation phase, the Brown cable must be connected to the same phase
as the Black cable, and the Blue or Grey cable to the neutral wire. The Green/Yellow cable must be connected to
the earth.
