The table below contains data relevant to the overall dimensions (see also the previous figure).
These data vary according to the maximum measurements of the pieces to be machined (length
and width) and for which the machine has been equipped. The values are given in millimetres.

The quality of the electric system must guarantee the essential requirements as stated in the CEI
60204-1 and IEC 204-1 standards, unless otherwise agreed with the customer.
n Supply Voltage: (see rating plate) with a tolerance of ± 10%
n Supply Voltage Frequency: (see rating plate) with a tolerance of ± 2%
n Max. Electrical Input: (see rating plate)
n Harmonic Distortion: from the second to the fifth < 10% + from the sixth to the thirtieth < 2%
n Three-phase Supply Voltage Imbalance: < 2%
n Voltage Impulses: duration less than 1.5 ms and < 200% of supply voltage
n Voltage Interruption: duration < 3 ms; period > 1 second
n Voltage Drops: value < 20% of peak supply voltage; period > 1 second
n System compliance with standards: CEI 64-8, IEC 364
Machine protection against indirect contacts has been designed for mains supplies of the rated
voltage type. Therefore, no
differential guard has been fitted. In the event that the machine is to be
connected to a different supply mains (TT, IT) or if foreseen by local laws or regulations, it is
necessary to fit differential guards according to the characteristics of the system and taking into
account the following conditions:
1. Measures to contain electromagnetic interference may cause high levels of high-frequency
dispersion current along the earth wire. For this reason it is necessary to choose a differential
switch that is not affected by high frequencies.
