● Limit value for 1 st environment is also relevant, if source of
interference of 2

environment.
● Designations “class” and “group” according to IEC CISPR
11.
● QSP: measuring method quasi peak measurement.
● AV: measuring method arithmetic averaging.
Second Environment, Industrial
Area
Facilities not directly connected to a low-voltage mains to supply buildings in
residential areas.
If the limit values in an industrial area separated from public supply by a
transformer station only have to be complied with at the property boundary or
in the neighboring low-voltage mains, the filter might not be necessary. In the
vicinity such as measuring sensors, measuring lines or measuring devices, it
is normally required to use the interference suppression filter.
Increasing the noise immunity of a sensitive device can often be the
economically better solution compared to measures of interference
suppression at the drive system of installation.
First Environment Environment containing residential areas and facilities directly connected,
without interstage transformer, to a low-voltage mains supplying buildings in
residential areas.
Medium-sized manufacturing plants and industrial establishments can be
connected to the public low-voltage mains together with residential buildings.
In this case there is a high risk for radio and television reception if there are
not any measures for radio interference suppression taken. Therefore, the
indicated measures are generally recommended.
Nominal Current of Supply Mains The nominal current of the supply mains (＞ 100 A or ≤100 A) is specified by
the local power supply company at the connection point of the mains. For
industrial companies, for example, such connection points are the
interconnecting stations from the power supply company.
Unrestricted Distribution Channel of distribution for which placing on the market is independent of the
EMC expert knowledge of the customer or user of electric drives.
Restricted Distribution Channel of distribution for which the placing on the market is restricted to
traders, customers or users who individually or together have technical expert
knowledge of EMC for the use of electric drives.
Since it is impossible to obtain the lower limit values for residential areas with
all applications by means of usual measures (like in the case of large and
electrically not closed installations, longer motor cables or a large number of
drives), the following note included in EN 61800-3 has to be observed.
Components of the drive system Rexroth Fv are products of
category C3 (with restricted distribution) according to IEC
61800-3. They are not provided for use in a public low-voltage
mains supplying residential areas. If they are used in such a
mains, high-frequency interference is to be expected. This can
require additional measures of radio interference suppression.
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 the Frequency
Converter Fv.
