EMC Emissions
The SINAMICS G110D inverters have been tested in accordance with the emission
requirements of the category C2 (domestic) environment.
Table A- 2 Conducted & Radiated Emissions
EMC Phenomenon
Standard
Level
Conducted Emissions
EN 55011
Class A
Radiated Emissions EN 55011 Class A
Note
To achieve this performance the default switching frequency should not be exceeded and
the recommended cables and connectors should be fitted correctly.
Achieving radiated emissions to EN 55011 Class B is largely dependent on the inverter
being correctly installed inside a metallic enclosure. The limits will not be met if the inverter is
not enclosed or installed in accordance with good EMC practices.
Harmonic Currents
The harmonic current emissions from the SINAMICS G110 D inverters is as follows:

Note
Units installed within the category C2 (domestic) environment require supply authority
acceptance before connection to the public low
-voltage power supply network. Please
contact your local supply network provider.
Units installed within the category C3 (industrial) environment do not require connection
approval.
