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.
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 Fv drive system are products of category C3
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 Bosch Rexroth
Frequency Converter Fv.
