Note:
⚫ The rated input voltage drop of input reactors is 2%±15%.
⚫ The current adjustment coefficient on the input side of the inverter is higher than 90% after a DC
reactor is configured.
⚫ The rated output voltage drop of output reactors is 1%±15%.
⚫ DC reactors are externally connected. You need to specify whether external or built-in reactors
are needed in your purchase order.

J10 is not connected in factory for the 380V 110kW and lower inverter models. Connect the J10
packaged with the manual if IEC/EN 61800-3 C3 requirements need to be met.
J10 is connected in factory for the 380V 132kW and higher inverter models, all of which meet IEC/EN
61800-3 C3 requirements.
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.
