3.1 EMC-compliant setup of the machine or plant
The converter is designed for operation in industrial environments where strong
electromagnetic fields are to be expected.
Reliable and disturbance-free operation is only guaranteed for EMC-compliant installation.
To achieve this, subdivide the control cabinet and the machine or system into EMC zones:

Figure 3-1 Example of the EMC zones of a plant or machine
Inside the control cabinet
● Zone A: Line supply connection
● Zone B: Power electronics
Devices in Zone B generate energy-rich electromagnetic fields.
● Zone C: Control and sensors
Devices in Zone C do not generate any energy-rich electromagnetic fields themselves, but
their functions can be impaired by electromagnetic fields.
Outside the control cabinet
● Zone D: Motors
Devices in Zone D generate electromagnetic fields with a significant amount of energy
