Control cabinet

The inverter is designed for operation in industrial environments where high-level
electromagnetic fields are to be expected.
Reliable and disturbance-free operation of the inverter is only ensured if the inverter is
installed in compliance with EMC regulations.
EMC zones within the control cabinet
● Subdivide the control cabinet and the machine or plant into EMC zones:
Image 4-1
– Zone A: Line supply connection
– Zone B: Power electronics
– Zone C: Control and sensors
– Zone D: Motors, braking resistors outside the control cabinet

Example of the EMC zones of a plant or machine
Devices in Zone B generate energy-rich electromagnetic fields.
Devices in Zone C do not generate any energy-rich electromagnetic fields themselves,
but their functions can be impaired by electromagnetic fields.
Devices in Zone D generate electromagnetic fields with a significant amount of energy
