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 (P/+, N/-) and the terminal symbols of the power regeneration common converter (FR-CV) are the same.
After making sure that the wiring is correct, set "2" in Pr. 30 Regenerative function selection. (Refer to page 83.)

*1 Remove the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 of the inverter, and connect the
control circuit power supply across terminals R1/L11-S1/L21. Always keep the power input terminals R/
L1, S/L2, T/L3 open. Incorrect connection will damage the inverter. (E.OPT (option alarm) will occur.
(Refer to page 236.)) Opposite polarity of terminals N/-, P/+ will damage the inverter.
Do not insert an MCCB between the terminals P/+ − N/- (between P/L+ − P/+, between N/L- − N/-).

*3 Assign the terminal for X10 signal using any of Pr. 178 to Pr. 189 (input terminal function selection).
(Refer to page 85)
*4 Be sure to 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.
CAUTION
1. Use sink logic when the FR-CV is connected. The FR-CV cannot be connected when source logic (factory setting) is
selected.
2. The voltage phases of terminals R/L

Connection of the power factor improving DC reactor (FR-HEL)

When using the DC reactor (FR-HEL), connect it between terminals P1-P/+
In this case, the jumper connected across terminals P1-P/+ must be removed. Otherwise, the reactor will not exhibit
its performance.
CAUTION
1. The wiring distance should be within 5m.
2. The size of the cables used should be equal to or larger than that of the power supply cables (R/L1, S/L2, T/L3).
