2.10.7 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-A820-03160(55K) or lower and the FR-A840-01800(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 743 .) Three-phase AC power supply *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 page 812 .)) *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 page 539 .) *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 RDYB on the FR-CV to a terminal where the X10 signal or MRS signal is assigned on the inverter. Always connect terminal SE on the FR-CV to terminal SD on the inverter. Not connecting these terminals may damage the FR-CV. 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. 108 2.
