11. OPTIONS AND AUXILIARY EQUIPMENT
(5) Other precautions
(a) Always use the FR-CVL-(H) as the power factor improving reactor. Do not use the FR-BAL or FR-BE L.
(b) The inputs/outputs (main circuits) of the F R-CV-(H) and servo amplifiers include high-fr equency
components and may provide electromagnetic wav e interference to communication equipment (such as
AM radios) used near them. In this case, inter ference can be reduced by installing the radio no ise filter
(FR-BIF-(H)) or line noise filter (FR-BSF01, FR-BLF).
(c) The overall wiring length for connection of the DC power supply between the FR-CV-(H) and servo
amplifiers should be 5m or less, and the wir ing must be twisted.
