J10 is not connected in factory for VFD models of 110G/132P and lower. Connect the J10 packaged with the manual if the requirements of level C3 need to be met;
J10 is connected in factory for VFDs of 132G/160P and higher, all of which meet the requirements of level C3.
Note:
Disconnect J10 in the following situations:
l 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.
l 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.
INVT provides some of the filters for you to choose.
