3.4 ELECTRIC CONNECTIONS
DANGER
Skilled operators must arrange the electric connections.
DANGER
Before connecting, see the attached electric diagram and the plate on the machine for the
information about the voltage, the frequency, etc.
DANGER Connect the ground by the terminal PE (yellow-green) before making any other
connections.
DANGER
Connect the ground by the terminal PE (yellow-green) before making any other
connections.
ELECTRIC TOLERANCES:

Real voltage

10 % of the nominal one

Frequency :

1 % of the nominal one in a continuous way;

2 % of the nominal one for a short period

The harmonic distortion of the sum from the second to the fifth harmonics not more than 10 % of the total
voltage as a real value between the conductors. A further distortion of 2% is accepted for the sum from
the sixth to the thirtieth harmonics of the real total value between the conductors.

With reference to the tension unbalance of the three-phase voltage, the inverted sequence component
and the zero sequence component must not be more than 2% of the direct sequence component of the
voltage

The voltage pulses must not last more than 1,5 ms with an up/down time between 500 ms and 500

s and
a peak value not higher than 200 % of the real value of the nominal tension.

The electric feeding must not be interrupted or zeroed for more than 3 ms. Between two interruptions it
must not take more than 1 s.

The interruptions must not overcome 20 % of the tension peak for more than one cycle. Between two
interruptions it must not take more than 1 s
