selectable and can be enabled or disabled by the Jumper J10. The default setting (factory setting) is
that the C3 Filter is enabled which means the jumper J10 is inserted. If required, please remove the
jumper J10 to disable the integrated C3 filter.
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.
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
and motors and the leakage current of conducting wires.
HITACHI provides some of the filters for users to choose.
