4.1.3 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 according to EN 55011. By implementing appropriate additional measures,
the limit values according to category C2 or limit value class A, Group 1, are observed. Further,
additional measures may be required, for instance, using an additional radio interference
suppression filter (EMC filter).
The measures for EMC-compliant design of the system are described in detail in this manual
respectively in the Installation Guideline EMC.
Please note that the final statement on compliance with the standard is given by the respective
label attached to the individual unit.
4.1.4 EMF assessments for 24 V components
The 24 V components, e.g. control systems (NCU, MCU, PPU), PCUs/IPCs, operator panels,
handheld terminals and machine control panels do not generate any appreciable
electromagnetic fields.
No minimum clearance has to be maintained for 24 V components.
4.2 Climatic and mechanical environmental conditions
