Limit Values for Line-Based Disturbances (IEC 61800-3); Limit Value
Characteristic through Frequency Range
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 of broadcast receivers or other sensitive devices as regards high-fre‐
quency, 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 econom‐
ically better solution compared to measures of interference suppression at
the drive system of the 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
aren't 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 in‐
dustrial companies, for example, such connection points are the interconnect‐
ing stations from the power supply system.
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 the usual measures (like for example 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 IndraDrive 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 re‐
quire additional measures of radio interference suppression.
See the following chapters for the limit value classes (as per categories C1,
C2, C3, C4 according to EN 61800‑3) which can be reached for the individual
drive systems and devices:
