EMC-compliant installation

EMC-compliant installation of the inverter
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 375)". It allows easy and
efficient connection of the necessary shield to achieve EMC-compliant installation of the
inverter. 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 inverter frame
size B/C.
NOTICE
Inverter damage due to improper mains disconnection
Improper mains disconnection can cause inverter damage.
Do not perform mains diconnection on the motor-side of the system if the inverter is in
operation and the output current is not zero.
Note
Cable connection
Separate the control cables from the power cables as much as possible.
Keep the connecting cables away from rotating mechanical parts.
