7.7 Electromagnetic compatibility of the inverter
Interference emission
• Low-frequency, conducted interferences (harmonics)
Your line supply defines as to whether the converter can satisfy the requirements of the first
environment, Category C2.
In this regard, contact your network operator.
• High-frequency conducted interferences:
The limit values for the first environment, Category C2, are maintained under the following
preconditions:
– You are using a converter with an integrated filter
– You are using a shielded motor connection cable with low capacity
– The current does not exceed the value of the LO input current
– The pulse frequency does not exceed 4 kHz
– The motor cable is shorter than 25 m
– The installation must be carried out by an expert who has the necessary experience for
• High-frequency emitted interference
When installed professionally in accordance with EMC guidelines, the converters fulfill the
requirements of the standard in relation to category C2.

EMC limit values in South Korea

The EMC limit values to be observed for Korea correspond to the limit values of the EMC product
standard for variable-speed electric drives EN 61800-3 of category C2 or the limit value class A,
Group 1 to KN11.
By implementing appropriate additional measures, the limit values according to category C2 or
limit value class A, Group 1, are observed.
Additional measures, such as the use of an additional RFI suppression filter (EMC filter), may be
necessary.
In addition, measures for EMC-compliant configuration of the plant or system are described in
detail in this manual.
You can find additional information about EMC-compliant configuration of the plant or system
