2.8.6 Connection of the power regeneration common
converter (FR-CV)
When wiring for connecting the power regeneration common converter (FR-CV) to the inverter, make sure to match the terminal
symbols (P/+, N/-) on the inverter and on the power regeneration common converter.
The FR-CV is compatible with the FR-F820-02330(55K) or lower and the FR-F840-01160(55K) or lower.
After making sure that the wiring is correct and secure, set "2 or 102" in Pr.30 Regenerative function selection. (Refer to
page 566.)

*1 Remove jumpers across terminals R/L1 and R1/L11 as well as across terminals S/L2 and S1/L21, and connect the power supply for the control
circuit to terminals R1/L11 and S1/L21. Do not connect anything to power input terminals (R/L1, S/L2, and T/L3). Incorrect connection will damage
the inverter. (The E.OPT fault (Option fault) occurs. (Refer to
*2 Instead of connecting the terminals to the AC power supply, the control circuit can be powered by connecting terminal R1/L11 to terminal P/+ and
terminal S1/L21 to terminal N/-. In this case, do not connect the terminals to the AC power supply. Doing so will damage the inverter.
*3 When the FR-CV is connected, the jumper across terminals P/+ and P1 does not affect the function. (The FR-CV can be connected with the
jumper connected.)
*4 Do not install an MCCB across terminals P/+ and N/- (between terminals P/L+ and P/+ or between N/L- and N/-). Connecting the opposite polarity
of terminals N/- and P/+ will damage the inverter.
*5 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the terminals used for the X10 signal. (Refer to
*6 Be sure to connect the power supply and terminals R/L11, S/L21, and T/MC1. Operating the inverter without connecting them will damage the
power regeneration common converter.
*7 Always connect terminal RDY on the FR-HC2 to a terminal where the X10 signal or MRS signal is assigned on the inverter. Always connect
terminal SE on the FR-HC2 to terminal SD on the inverter. Not connecting these terminals may damage the FR-CV.
NOTE
• The voltage phases of terminals R/L11, S/L21, and T/MC1 and the voltage phases of terminals R2/L1, S2/L2, and T2/L3 must
be matched.
• Use the sink logic when the FR-CV is connected. It cannot be connected when the source logic is selected.
• Do not connect a DC reactor (FR-HEL) to the inverter when the FR-CV is connected.
