■Radio noise filter (FR-BIF(-H))
This filter is effective in suppressing noise radiated from the power supply side of the converter unit, especially in 10 MHz and
lower radio frequency bands. The FR-BIF(-H) is designed for the input only.
200 V class: FR-BIF
400 V class: FR-BIF-H
Connection diagram
Make the connection cables as short as possible. Grounding is required.
When using the FR-BIF(-H) with a single-phase power supply, insulate
unconnected lead wires.

■Varistor for input power supply (recommended)
Varistors are effective to prevent exogenous noise and lightning surges from entering the converter unit. When using a
varistor, connect it between each phase of the input power supply of the equipment. For varistors, the TND20V-431K,
TND20V-471K, and TND20V-102K manufactured by Nippon Chemi-Con are recommended. For detailed specification and
usage of the varistors, refer to the manufacturer catalog.
