11.8.2.2 High-frequency interference emissions EMC category C2
Description
The drive meets the limit values of IEC 61800-3 Category C2 with regard to conducted and
radiated interference emissions under the following conditions:
● Operation on TN or TT line supply with grounded neutral point
● Permissible motor cable length
Maximum permissible motor cable length (Page 82)
● Shieled motor cable with low capacitance
● Pulse frequency ≤ factotory setting
● With C2 line filter (external or internal)
– Converters with integrated C2 line filter
– Unfiltered FSA … FSF converters with external C2 line filter
– FSH/FSJ converters with external C2 line filter and line reactor
Note
If devices without integrated C2 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 C2. Separate line filters for each device or a shared line filter for several
devices can be used.
11.8.2.3 Current harmonics
Overview
IEC 61800-3 does not define any limits for the emission of current harmonics when used in
industrial networks. A system evaluation according to IEC 61000-3-14 or 61800-3 Annex B.4
is recommended.
