Connection of stand-alone option units
Connection of the power regeneration common converter FR-CV
When connecting the power regeneration common converter (FR-CV), make connection so that
the inverter terminals (+, −) and the terminal symbols of the power regeneration common con-
verter (FR-CV) are the same.

Always keep the power input terminals R/L1, S/L2, T/L3 open. Incorrect connection will
damage the inverter.
Do not insert an MCCB between the terminals + and − (between P/L+ and +, between N/
L− and −). Opposite polarity of terminals −, + will damage the inverter.
Always connect the power supply and terminals R/L11, S/L21, T/MC1. Operating the inverter
without connecting them will damage the power regeneration common converter.
Use Pr. 178 to Pr. 184 "Input terminal function selection" to assign the terminals used for
the X10, RES signal. (Refer to section 6.10).
Be sure to connect terminal RDYB of the FR-CV to the X10 signal or MRS signal assigned
terminal of the inverter, and connect terminal SE of the FR-CV to terminal SD of the inverter.
Without proper connecting, FR-CV will be damaged.
The voltage phases of terminals R/L11, S/L21, T/MC1 and terminals R2/L1, S2/L2, T2/L3
must be matched.
Use sink logic when the FR-CV is connected. The FR-CV cannot be connected when source
logic (factory setting) is selected.
Do not remove a jumper across terminal + and P1.
