Note:
1.
The rated input voltage drop of input reactors is 2%±15%.
2.
The current adjustment coefficient on the input side of the inverter is higher than 90% after a DC
reactor is configured.
3.
The rated output voltage drop of output reactors is 1%±15%.
4.
The preceding table describes external accessories. You need to specify the ones you choose
when purchasing accessories.

J10 is not connected in factory for inverters of 400V (≤
110kW). Connect the J10 packaged with the
manual if the requirements of level C3 need to be met;
J10 is connected in factory for inverters of 400V (≥
132kW), all of which meet the requirements of
level C3.
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 inverters (when used) on the
surrounding devices.
Noise filters on the output side can decrease the radio noise caused by the cables between inverters
