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 power regeneration common converter (FR-CV) terminals as shown below so that
their symbols match with each other.
The FR-CV is applicable to the FR-A820-03160(55K) or lower and the FR-A840-01800(55K) or lower.
After making sure that the wiring is correct, set "2" in Pr. 30 "Regenerative function selection". (Refer
to page 5-713.)

Fig. 2-69:
Remove jumpers between terminals R/L1 and R1/L11 as well as between 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, T/L3). Incorrect connection will damage the inverter.
(E.OPT (option fault) will occur. (Refer to page 6-28.)
Do not insert an MCCB between 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.
Use Pr. 178 to Pr. 189 (input terminal function selection) to assign the terminals used for the X10
signal. (Refer to page 5-439.)
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.
Always connect terminal RDYB of the FR-CV to the inverter terminal where the X10 signal or the
MRS signal is assigned to. Always connect terminal SE of the FR-CV to the inverter terminal SD. Not
connecting these terminals may damage the FR-CV.
NOTES 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 (factory setting) 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 FR-CV is connected.
