EMC-compliant installation
EMC-compliant installation of the inverter
The screening plate kit is supplied as an option for each frame size (For more information
about this option, see Appendix "Screening plate kit (Page 260)".). It allows easy and
efficient connection of the necessary screening to achieve EMC-compliant installation of the
inverter. If no screening plate kit is used, you can alternatively mount the device and
additional components on a metal mounting plate with excellent electrical conductivity and a
large contact area. This mounting plate must be connected to the cabinet panel and the PE
or EMC bus bar.
The following diagram shows an example of EMC-compliant installation of the inverter frame
size B/C.
