Check that:
—
the characteristics of the power network are suitable for
the device usage values
—
the power supply voltage corresponds to the nominal va-
lue +/- 10%, with a maximum phase imbalance of 3%
—
all of the power network disconnect devices must be
equipped with contact openings (3 mm) in order to allow
for complete disconnection, in accordance with the con-
ditions required
Mandatory items:
—
have an omnipolar magneto-thermal circuit breaker and
a padlockable disconnecting switch compliant with the
IEC-EN Standards (contact opening of at least 3 mm), with

stalled near the equipment
—
connect the device to a properly functioning earthing sy-
stem
—
make sure that the electrical power supply system is com-
pliant with the current national safety standards
—
make sure that the power supply line impedance is consi-
stent with the unit's power consumption, as indicated on
the unit's data plate
—
for any electrical intervention, always refer to the wiring
diagrams contained within this booklet
—
take anti-static precautions in case of weather conditions
where humidity is less than 40%
