J10 is not connected in factory for VFDs of 022G/030P and below. Connect the J10 packaged with the manual if the requirements of level C3 need to be met;
Note:
Disconnect J10 in the following situations:
1. 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.
2. 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 users to choose.

Note:
1. The input EMI meets the C2 requirements after an input filter is configured.
2. The preceding table describes external accessories. You need to specify the ones you choose when purchasing accessories.
