(b) Example of selecting the wire sizes
When connecting multiple servo amplifiers, always use junction terminals for wiring the servo
amplifier terminals P4, N-. Also, connect the servo amplifiers in the order of larger to smaller
capacities.

(5) Other precautions
(a) When using the FR-CV-(H), always install the dedicated stand-alone reactor (FR-CVL-(H)). Do not
use the power factor improving AC reactor (FR-HAL-(H)) or power factor improving DC reactor (FR-
HEL-(H)).
(b) The inputs/outputs (main circuits) of the FR-CV-(H) and servo amplifiers include high-frequency
components and may provide electromagnetic wave interference to communication equipment (such
as AM radios) used near them. In this case, interference can be reduced by installing the radio noise
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 5 m or less, and the wiring must be twisted.
