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.
MCCB
Three-phase
AC power supply
*1
Do not connect anything to power input terminals (R/L1, S/L2, T/L3). Incorrect connection will damage the inverter.
*2
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.
*3
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.
*4
Use Pr.178 to Pr.182 (Input terminal function selection) to assign the terminals used for the X10 signal or the RES signal. (Refer to
*5
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 (factory setting).
• Do not connect a DC reactor (FR-HEL) to the inverter when the FR-CV is connected.
