AC power input
Connect to the dedicated stand-alone reactor terminals R2/L12, S2/L22, T2/L32.
P/L+, N/L-
DC power output
Connect to the inverter terminals P, N, and keep the inverter terminals R, S, T open.
For the FR-A700, F700, A500, F500 or V500 series, set 2 (for use of high power
factor converter, power regeneration common converter) in Pr.30.

Power supply phase
detection
Terminals for power supply phase, power voltage detection and control power input.
Connect to the dedicated stand-alone reactor terminals R/L11, S/L21, T/L31.
Running the inverter without connecting these terminals will damage the power
regeneration common converter.
Ground
Securely connect to the earth.

24VDC input
Used to input 24VDC power for alarm output relay drive and reset drive signal
drive. Connect to the inverter terminal PC. When you do not use the inverter
terminal PC, prepare a 24VDC power supply.
Permissible input voltage fluctuation: 22V to 26VDC
RES
Reset
Used to reset the activated protective circuit. Turn the terminals RES-SD on for
longer than 0.1 seconds, then turn them off.

RDYA
Ready output
Outputs a signal when the power regeneration common converter is ready to
operate.
This output has opposite logic to RDYB.
Permissible load 24V 0.1ADC
RDYB
Inverter
operation enable
Outputs a signal when the power regeneration common converter is faulty or the
reset signal is input. Connect to the X10 (MRS) signal of the inverter. This output
has opposite logic to RDYA.
Permissible load 24V 0.1ADC
RSO
Converter reset
Outputs the reset signal to the inverter when the reset signal is input to the power
regeneration common converter. Connect to the inverter terminal RES.
Permissible load 24V 0.1ADC

Alarm output
Change-over outputs which indicate that the protective function of the power
regeneration common converter was activated to stop the output.
Alarm: No continuity across B-C (continuity across A-C), normal: Continuity across

For the FR-A700, F700, A500, F500 or V500 series, remove the jumpers across
the inverter terminals R-R1 and S-S1, and input external power to these terminals.
For the FR-E500, S500, C500 or F500J series, the inverter does not have the
terminals R1, S1 so uses the DC power input from the terminals P, N as the control
power.

FR-E500, S500, C500 or F500J series, use the terminal MRS as you cannot
assign the X10 signal. If the terminal MRS is already used, assign another MRS
signal to any of the input terminals.

RES
Converter reset
When the reset signal is input to the power regeneration common converter, the
reset signal is also input to the inverter. Connect to the power regeneration
common converter terminal RSO. For the D700, S500, C500 and F500J series,
assign the RES signal to any one of the input terminals.
