Drive System Applications; Emitted Interference/Interference Immunity - Siemens Sinamics S120 Manual

6.3.3

Drive system applications

SINAMICS S120 units are designed for use in the second environment.
The drive system must be installed by appropriately qualified personnel (professional
person) in compliance with EMC regulations - and the installation notes provided in the
manual.
More detailed requirements on how to comply with a specific EMC category can be found in
the SINAMICS S120 Manual "Booksize Power Units" (GH2).
6.3.4

Emitted interference/interference immunity

Limiting interference emission
Radio interference suppression filters are required in order to limit interference emission.
These filters can either be integrated in the unit, or externally mounted.
● It is not permissible to use Basic Line Filters in IT line systems.
● For Active Interface Modules and Basic Line Modules in IT line systems, the connection
screw or the connection bracket to the radio interference suppression capacitor with
respect to ground must be removed.
● In conjunction with Smart Line Modules, to reduce symmetrical interference emission,
special filters can be used (without capacitors to ground).
Interference immunity
With reference to interference immunity, SINAMICS S120 units can also be used in the first
environment.
Note
Integrating SINAMICS S120 in other plants/machines
When variable-speed drive systems are integrated in other plants/machines, additional
measures may be required in order to comply with their product standards.
With respect to the compliance with limits for harmonic currents, the EMC product standard
EN61800-3 for drive systems (PDS) refers to compliance with standards EN 61000-3-2 and
EN 61000-3-12.
Converters are classified as equipment used on a professional basis, deployed in certain
areas of business and industry - and are not operated in the general public domain.
The following general conditions must be observed when used in the first environment:
● The drive system must be installed in compliance with EMC regulations by appropriately
trained professionals.
● The converters must be equipped with a Category C2 line filter.
● The device-specific information and instructions for maintaining harmonic current limits
must be complied with.
