Note:
Disconnect J10 in the following situations:
The EMC filter is applicable to the neutral-grounded grid system. If it is used for the IT

grid system (that is, non-neutral grounded grid system), disconnect J10.
If leakage protection occurs during configuration of a residual-current circuit breaker,

disconnect J10.
Note: Do not connect C3 filters in IT power systems.
Interference filters on the input side can reduce the interference of VFDs (when used) on the
surrounding devices.
Noise filters on the output side can decrease the radio noise caused by the cables between
VFDs and motors and the leakage current of conducting wires.
Kruger provides some of the filters for you to choose.
