Connection of stand-alone option units
Connect between the inverter terminal P/+ and the converter terminal P4 and between the inverter terminal N/- and the converter terminal N/- for
polarity consistency.
Connecting opposite polarity of terminals P/+ and N/- will damage the converter and the inverter.
Confirm the correct phase sequence of three-phase current to connect between the reactor and the converter, and between the power supply
and the reactor.
Incorrect connection will damage the converter.
Be sure to connect the power supply and terminals R/L1, S/L2, and T/L3 of the converter. Operating the inverter without connecting them will
damage the converter. A branch point to each of these terminals must be placed between the power supply and the AC reactor.
Install the AC reactor between the node points joined to the converter terminals R/L1, S/L2, and T/L3 and the node points joined to the FR-XCL
reactor. To select an appropriate model, refer to the FR-XC Instruction Manual.
To use separate power supply for the control circuit, remove each jumper at terminal R1/L11 and terminal S1/L21.
To select an appropriate MCCB, refer to the FR-XC Instruction Manual.
Install UL listed fuses on the input side of the reactor to meet the UL/cUL standards (refer to the FR-XC Instruction Manual for information about
the fuse).
Do not install an MCCB or MC between the reactor and the converter. Doing so disrupts proper operation.

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-A846-01800(55K) or lower.
After making sure that the wiring is correct, set "2" in Pr.30 Regenerative function selection.

Three-phase
AC power
supply
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.
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 Instruction Manual (Detailed).
