6.9 Parameter Settings for IT Mains
If the drive is supplied from an isolated mains (IT mains, floating delta, or grounded delta) or TT/TN-S mains with grounded leg, it is
recommended to check the parameter settings of the grid type and RFI. The filter capacitors between the chassis and the DC link should
be cut off via the parameters to avoid damage to the DC link and to reduce the ground capacity currents.
See more information in the iC7 Series Industry Application Guide.
Keep the filter capacitors between the chassis and the DC link in these cases:
l When optimal EMC performance is needed.
l When parallel motors are used.
l When the motor cable is longer than 25 m (82 ft).
