EMC Overall Performance

EMC Emissions
The SINAMICS G120 drives have been tested in accordance with the emission requirements
of the category C2 (domestic) environment.

Radiated Emissions
Note
To achieve this performance the default switching frequency should not be exceeded.
In order to achieve conducted emissions to EN 55011 Class B there is a range of PM240
external filter options available.
Achieving radiated emissions to EN 55011 Class B is largely dependent on the drive being
correctly installed inside a metallic enclosure. The limits will not be met if the drive is not
enclosed or installed in accordance with good EMC practices.
Harmonic Currents
The harmonic current emissions from the SINAMICS G120 drives is as follows:

Note
Units installed within the category C2 (domestic) environment require connection to the
public low-voltage power supply network. Please contact your local supply network provider.
