Radio interference suppression filters must be used, and the maximum total cable lengths
complied with in order that the drive system complies with the requirements related to
Category C3.
● ALM with AIM up to 350 m
● BLM with line reactor up to 350 m
● BLM with line reactor and Basic Line Filter up to 630 m
When the drive system is connected to IT line systems, the following combinations are
permissible so that the requirements related to Category C4 are complied with.
● ALM with HF reactor without Line Filter
● ALM with AIM (remove the connection bracket)
● SLM with line reactor without Line Filter
● BLM (remove the connection bracket) with line reactor without Line Filter
Emitted interference/interference immunity
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, 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).
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.
