3.8.5 Connection of the power regeneration common converter FR-CV
When connecting the power regeneration common converter (FR-CV), connect the inverter terminals
(P/+, N/ ) and the terminals P/L+ and N/L– of the power regeneration common converter (FR-CV).
햲
Always keep the power input terminals R/L1, S/L2, T/L3 open. Incorrect connection will damage
the inverter.
햳
Do not insert an MCCB between the terminals P/+ and N/– (between P/L+ and P/+, between N/
L
and N/–). Opposite polarity of terminals N/–, P/+ will damage the inverter.
햴
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.
햵
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).
햶
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.

NOTES
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 P/+ and P1.
