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 on the Internet:

Protecting persons from electromagnetic fields

Overview
Protection of workers from electromagnetic fields is specified in the European EMF Directive
2013/35/EU. This directive is implemented in national law in the European Economic Area (EEA).
Employers are obligated to design workplaces in such a way that workers are protected from
impermissibly strong electromagnetic fields.
To this end, assessments and/or measurements must be performed for workplaces.
