Rexroth IndraDrive Electromagnetic Compatibility (EMC) 8-5
DOK-INDRV*-SYSTEM*****-PR02-EN-P
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-frequency, 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 the installation.
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.
The nominal current of the supply mains (>100A or <100A) 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 system.
Channel of distribution for which placing on the market is independent of
the EMC expert knowledge of the customer or user of electric drives.
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 high number of drives), the following note included in EN
61800-3/ A11, section 6.3 has to be observed.
Note: Components of the drive system Rexroth IndraDrive are
products of restricted distribution according to IEC61800-3! In
residential areas these products can cause radio interference.
In this case it can be necessary for the operating company to
take appropriate measures.
