Precautions for selecting peripheral devices
(4) Using options to suppress noises
By using the radio noise filter (FR-BIF) and the line noise filter (FR-BLF), the noise radiated from the connection cable
can be suppressed. Refer to the Instruction Manual of each option for the detail of the radio noise filter (FR-BIF) and the
line noise filter (FR-BLF).
Example (FR-A700 series)
Install the line noise filter to the terminal R, S, and T of the converter, but not to the power supply. Refer to the Instruction Manual of the noise filter for the
installation procedure of the noise filter.

NOTE
Configure a system where the magnetic contactor at the converter input side shuts off the power supply at a failure of
the converter or the connected inverter. (The converter does not shut off the power supply by itself.)
Failure to do so may overheat and burn the resistors in the converter and the connected inverter.
