10. RFI FILTER (Zero-phase Reactor)
The RFI Filter helps reduce radiated noise from the motor wiring. It is used on the output side of
the inverter. The example RFI Filter is shown below.
10.1. The wiring of ADrive Size-B and Size-C to RFI Filter
The toroidal transformer core comes with the inverter is used for RFI filter. The wiring must go
through the opening (U, V, W) to reduce the RF component of the electrical noise. Loop the
wires two times to attain the full RFI filtering effect. Install the toroidal core near the inverter as
close as possible.
10.2. The wiring of ADrive Size-D RFI Filter
The toroidal transformer core comes with the inverter is used for RFI filter. The wiring must go
through the opening (U, V, W) to reduce the RF component of the electrical noise. Loop the wire
one time to two toroid to attain the full RFI filtering effect. Install the toroidal cores near the
inverter as close as possible.
