EMC-compliant installation of a plant or machine

The inverter 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:
EMC zones
Figure 4-1
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.
● Zone D: Motors, braking resistors outside the control cabinet
Devices in Zone D generate electromagnetic fields with a significant amount of energy
Outside the control cabinet
●
Devices in Zone D generate electromagnetic fields with a significant amount of energy
