EMC line filter
EMC line filters for submounting can be selected as an option.
The filters are identical in height and width to the dimensions of the FI and have the same hole pattern for joint mounting with the FI. (Dimensions: see data and dimension sheet).
EMC line filters are connected upstream of the frequency inverter on the mains side. They reduce the mains feedback of the frequency inverter to the values specified in the relevant standards (see also "General EMC information")
General EMC information
Electromagnetic compatibility (EMC) refers to the ability of an electrical or electronic device to function satisfactorily / as intended in its intended environment without unduly influencing this environment through self-generated electromagnetic currents. The legal basis in Germany is the EMC Act. The EMC standard for electrical drive systems used to implement the provisions of the EMC Act is EN 61800-3. Some definitions of this standard that are particularly important in practice are presented below. For detailed information, see the ZVEI EMC guide for electrical drive systems and EN 61800-3.
First environment (residential, commercial and industrial): Environment that contains living areas and also equipment that is connected directly to a low-voltage network that supplies residential buildings without an intermediate transformer.
Second environment (industrial area): Facilities that are not directly connected to a low-voltage network supplying residential areas.
Category C1 equipment
Rated voltage <1000V for use in the first environment.
Category C2 devices
For use in the first environment that meet all the following criteria:
- Rated voltage < 1000 V
- Not connected via plug-in devices
- Not portable
- Connection and commissioning may only be carried out by persons with technical EMC expertise
Category C3 devices
- Rated voltage < 1000V, for use in the second environment. Use in the first environment is not intended.
- Warning in the documentation: This device is not intended for connection to the public mains. EMC interference may occur when connected to these networks
Category C4 devices
For use in the second environment that meet at least one of the following criteria:
- Rated voltage > 1000 V
- Rated current > 400A
- Connection to IT networks
- Required dynamic properties are not achieved due to the EMC filter settings
- An EMC plan must be drawn up!
