9.1.4 EMC Directive Compliance with Imminent 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 MICROMASTER, MIDIMASTER,
MICROMASTER Eco and COMBIMASTER ranges, which are classified as
"Professional Equipment" within the terms of the standard, fulfill the requirements
of the standard.
Special considerations for 250W to 550W drives with 230V 1ac mains supplies
when used in non-industrial applications
Units in this voltage and power range will be supplied with the following warning:
”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 Networks1 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

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