18Note about the A.C. power
According to the EN 60204-1:1997 standard, the machine is provided for A.C. supplies corresponding to the ex-
tracted characteristics below :
4.3.2 A.C. supplies
Voltage:
Steady state voltage: from 0.9 to 1.1 of nominal voltage.
Frequency:
from 0.99 to 1.01 of nominal frequency continuously.
from 0.98 to 1.02 short time.
Harmonics:
Harmonic distortion not to exceed 10 % of the total r.m.s. voltage between live conductors for the sum of the second
through to the fifth harmonic. An additional 2 % of the total r.m.s. voltage between live conductors for the sum of the
sixth through to the 30th harmonic is permissible.
Voltage unbalance:
Neither the voltage of the negative sequence component nor the voltage of the zero sequence component in three-
phase supplies shall exceed 2 % of the positive sequence component.
Voltage interruption:
Supply interrupted or at zero voltage for not more than 3 ms at any random time in the supply cycle. There shall be
more than 1 second between successive interruptions.
Voltage dips:
Voltage dips shall not exceed 20 % of the peak voltage of the supply for more than one cycle. There shall be more
than 1 second between successive dips.
19Feeder cable sections
The feeder cable sections mentioned in our literature are given only as a guide.
To obtain a value perfectly suited to your own application and which takes account of the different correction factors
in respect of your plant, refer to the tables below.
Table 1 (in accordance with EN Standard 60204-1)
Values given for:
• Cable with copper conductors
• Cable with PVC insulation (for other insulants see Table 3)
• Ambient temperature 40°C max. (for others see Table 2)
• Three-phase cable under load without including starting currents
• BT / C/ E cable layout.
