In a domestic environment (category C1) EFC 3600 frequency converter with
internal EMC filter may cause radio interference in which case supplementary
mitigation measures may be required.
See the following chapters for the limit classes (as per categories C1, C2, C3,
C4 according to EN 61800-3) which can be reached for Bosch Rexroth
Frequency Converter EFC 3600.
11.2 Ensuring the EMC Requirements
Standards and Laws
On the European level there are the EU Directives. In the EU states these Direc-
tives are transformed into laws valid on a national level. The relevant directive
for EMC is EU Directive 2004/108/EC which was transformed on the national
level in Germany into the law EMVG (“Law concerning electromagnetic compati-
bility of devices”) of 2008-02-26.
EMC Properties of Components
Drive and control components by Rexroth are designed and built, in accordance
with the present state-of-the-art of standardization, according to legal regula-
tions of the EU Directive EMC 2004/108/EC and the German law.
The compliance with EMC standards was tested by means of a typical arrange-
ment with a test setup conforming to standard with the indicated internal and
external EMC filters.
● Category C3 requirements according to product standard EN 61800-3 have
been complied with for EFC 3600 with an internal EMC filter.
● Category C1 requirements according to product standard EN 61800-3 have
been complied with for EFC 3600 with an external EMC filter.
● Minimum immunity requirements in the second environment according to
product standard EN 61800-3 have been complied with for EFC 3600 with in-
ternal and external EMC filters.
Applicability for End Product
Measurements of the drive system with an arrangement typical for the system
are not in all cases applicable to the status in a machine or installation. Noise
immunity and noise emission strongly depend on:
● configuration of the connected drives
● number of the connected drives
● conditions of mounting
● site of installation
● radiation conditions
