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

Phase (R)
110V SINGLE PHASE WITH NEUTRAL WIRE (1-2 GROUP MACHINES)
IMPORTANT: The machines manufactured for use with 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 Brown cable must be
connected to this phase, and the Blue or Grey cable to the neutral wire. The Green/Yellow cable must be connected
to the earth.

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 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.

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