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 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)
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 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.
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 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.
3-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 supplies with a single phase of 220-240 V. In this case, the Black cable must be joined
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.
