4.4 EMC-compliant installation
EMC-compliant installation of the converter
The shield connection kit is supplied as an option for each frame size. For more information
about this option, see Appendix "Shield connection kits (Page 391)". It allows easy and
efficient connection of the necessary shield to achieve EMC-compliant installation of the
converter. If no shield connection 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 converter
frame size B/C.
NOTICE
Converter damage due to improper mains disconnection
Improper mains disconnection can cause converter damage.
Do not perform mains disconnection on the motor-side of the system if the converter is in
operation and the output current is not zero.
