SINAMICS G110 Operating Instructions
74 6SL3298-0AA11-0BP0
9.1.3 EMC Directive Compliance with Harmonics Regulations
From 1st January 2001 all electrical apparatus covered by the EMC Directive will
have to comply with EN 61000-3-2 "Limits for harmonic current emissions
(equipment input <= 16A per phase)".
All Siemens variable speed drives of the SINAMICS G110 range, which are
classified as "Professional Equipment" within the terms of the standard, fulfill the
requirements of the standard.
Special considerations for 120W to 550W drives with 230V 1ac mains supplies
when used in non-industrial applications
For units in this voltage and power range the following warning applies:
”This equipment requires supply authority acceptance for connection to the public
supply network”. Please refer to EN 61000-3-12 sections 5.3 and 6.4 for further
information. Units connected to Industrial Networks4 do not require connection
approval (see EN 61800-3, section 6.1.2.2).
The harmonic current emissions from these products are described in the table
below:

The allowed harmonic currents for “professional equipment” with an input power
>1kW are not yet defined. Therefore, any electrical apparatus containing the
above drives which has an input power >1kW will not require connection approval.
Alternatively, the necessity to apply for connection approval can be avoided by
fitting the input chokes recommended in the technical catalogues (except 550W
230V 1ac units).

Industrial Networks are defined as those which do not supply buildings used for domestic purposes.
