3.2
EMC-compliant installation of a machine or system
The converter is designed for operation in industrial environments where strong
electromagnetic fields are to be expected.
Reliable and disturbance-free operation is only ensured for EMC-compliant installation.
To achieve this, subdivide the control cabinet and the machine or system into EMC zones:
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, braking resistors
Devices in Zone D generate electromagnetic fields with a significant amount of energy
