4-core machines
220 V - 240 V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)
Phase (R)
Neutral
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 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.
400 V SINGLE PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)
Phase (R)
Phase (S)
Phase (T)
Neutral
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 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.
400 V TWO PHASE WITH NEUTRAL WIRE (1-2-3 GROUP MACHINES)
Phase (R)
Phase (S)
Phase (T)
Neutral
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 Brown cable to a different phase, and the Blue or Grey cable to
the neutral wire. The Green/Yellow cable must be connected to the earth.
110 V SINGLE PHASE WITH NEUTRAL WIRE (1-2 GROUP MACHINES)
IMPORTANT
The machines manufactured for use at 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.
Phase (R)
Neutral
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 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.
