Note
The drive as a component of machines or systems
For the integration of the drive in machines or systems, additional measures may be necessary
in order to comply with the product standards of these systems or machines. These additional
measures are the responsibility of the system or machine manufacturer.
Note
In a residential environment, the drive may cause radio interference. In such cases, additional
interference suppression measures may be required.
11.8.2 Operation in the Second EMC environment
11.8.2.1 High-frequency interference emissions EMC category C3
Description
The drive may be used in the second EMC environment if at least the limit values of IEC
61800-3 Category C3 with regard to conducted and radiated interference emissions are
complied with. The following requirements must be met for this purpose:
● Operation on TN or TT line supply with star-point grounded
● Permissible motor cable length
Maximum permissible motor cable length (Page 82)
● Shielded motor cable with low capacitance
● Pulse frequency ≤ factotory setting
● With line filter (external or internal)
– Converters with integrated C2 line filter or C3 line filter
– Unfiltered converters with external C2 line filter or C3 line filter
Note
If devices without integrated C3 filters or filters other than those listed above are used, the
machine builder or plant engineer must certify that the emitted interference does not exceed the
limit values of category C3. Separate line filters for each device or a shared line filter for several
devices can be used.
