6.2.2 Operation on public supply systems (compliance with EN 61000−3−2)
European standard EN 61000−3−2 defines limit values for the limitation of harmonic
currents in the supply system. Non−linear consumers (e.g. frequency inverters) generate
harmonic currents which "pollute" the supplying mains and may therefore interfere with
other consumers. The standard aims at assuring the quality of public supply systems and
reducing the mains load.
)
Note!
The standard only applies to public systems. Mains which are provided with a
transformer substation of their own as in industrial plants are not public and
not included in the application range of the standard.
If a device or machine consists of several components, the limit values of the
standard apply to the entire unit.
Measures for compliance with the standard
With the measures described, the controllers comply with the limit values according to EN
61000−3−2.

systems EN 61000−3−2 Limitation of harmonic currents
Total output at the
mains
Compliance with the requirements 1)
< 0.5 kW With additional mains choke
0.5 ... 1 kW Provide for three−phase mains supply 2)
> 1 kW No measures required
1) The additional measures specified bring about that solely the controllers comply with the requirements of
EN 61000−3−2. Compliance with the requirements for the machine/system is the machine/system manufacturer’s
responsibility!
2) Either carry out supply via three−phase isolating transformer or autotransformer (sec. 3 x 230 V) or use 400 V
controllers.
