INSTALLATION AND WIRING
2.9.6 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 FR-F846-01160(55K) or lower.
After making sure that the wiring is correct, set "2" in Pr.30 Regenerative function selection.
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 (initial setting for the FM type) when the FR-CV is connected. It cannot be connected when the source logic
is selected.
• For the parameter details, refer to the FR-F800 Instruction Manual (Detailed).
 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.
 Remove the jumper across terminals P/+ and P1.
 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.
 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.
