cables) into account. When the total length is longer than 50 m, an output reactor must be added on
the output side of the VFD. When the distance between the VFD and motor ranges from 50m to 100m,
select the reactor according to the following table. When the distance is longer than 100m, contact
INVT technical support.
Built-in DC reactors can be directly connected to 380V 30kW and higher VFD models. DC reactors
can improve the power factor, avoid damage to bridge rectifiers caused due to large input current of
the VFD when large-capacity transformers are connected, and also avoid damage to the rectification
circuit caused due to harmonics generated by grid voltage transients or phase-control loads.
