4.5 - ELECTRIC CONNECTION (Fig. 6)
HAZARD
• Check that all switches are in OFF po-
sition before electrically connecting the
machine.
• A grounding connection is absolutely
compulsory and the system must meet
the current regulations in the country
of installation.
• Check the power supply voltage (see
the indication label); it must match the
voltage of the local grid.
• The device in monophase congura-
tion must be connected to a power line
with maximum impedance equal to
(0.142+J0.089) Ohm.
HAZARD
• The power supply line must be tted
with a suitable omnipolar LINE DISCON-
NECTOR (automatic magnetothermal or
differential breaker) located upstream
of the control unit main switch, with a
minimum opening of contacts of 3mm.
• The grounding system must be compli-
ant with the national electrical regula-
tions current in the place of installation.
• The power supply cables must be sized
according to the maximum current re-
quired by the machine so that the total
voltage loss under full load is less than
2%.
• Data pertaining to the power supply line
must match those listed on the identi-
cation plate and those shown in the
technical specication table, which is
found in “chapter 2” of this manual.
HAZARD
Before performing the electrical connec-
tion, ensure that the LINE DISCONNEC-
TOR is tripped (line is not live).
IMPORTANT
The machine is delivered already ready
for the voltage requested upon ordering.
• The machine is connected to the grid by the supplied
power cable (1) and to a breaker (2) that is properly
sized for the machine power consumption.

IMPORTANT
The differential breaker located upstream
of the machine must be positioned in an
easily accessible area.
