(Refer to page 44.)
The breaker should be selected with care since a
large inrush current flows in the power regeneration
common converter at power on. (Refer to page 26.)
Install the magnetic contactor to ensure safety.
When installed, do not use it to start or stop the
inverter. It might reduce the power regeneration
common converter life.
(Refer to page 26.)
For power coordination, always install the
dedicated stand-alone reactor.
Incorrect wiring might lead to power regeneration
common converter damage. The control signal lines
should be kept away from the main circuit to protect
them from noise.
•Use the compatible inverter.
•The inverter life is influenced by ambient
temperature.The ambient temperature should be
as low as possible within the permissible range.
This must be noted especially when the inverter is
installed in an enclosure .
•Incorrect wiring might lead to inverter damage.The
control signal lines should be kept away from the
main circuit to protect them from noise.
Do not connect a power capacitor, surge suppressor
or radio noise filter to the output side.
Note: Note that when an electromagnetic
contactor (MC) and a no-fuse breaker
(NFB) are installed, switching off the
inverter during operation, then on again
will cause a starting current to flow,
affecting the inverter and motor. When
installing a no-fuse breaker (NFB) on the
output side, contact the NFB manufacturer
for selection of no-fuse breaker.
To prevent an electric shock, always ground the
dedicated stand-alone reactor, power regeneration
common converter, motor and inverter.
The grounding cable provided for reduction of
induction noise from the power line of the inverter is
recommended to be wired by returning it to the
grounding terminal of the inverter.

Installation
2.1 Installation
2.1.1 Instructions for installation
1) Handle the unit carefully.
The power regeneration common converter uses plastic parts. Handle it gently to protect it from damage. Also,
hold the unit with even strength and do not apply too much strength to the terminal block cover alone.
2) Install the inverter in a place where it is immune to vibration. (5.9 m/s
Also note the cart, press, etc.
3) Note on ambient temperature
The power regeneration common converter life is under great influence of ambient temperature. Exercise care
so that the ambient temperatures of the installation place do not fall out of the permissible range (-10°C to
+50°C (14°F to 120°F)). Make sure that the ambient temperatures are within the permissible range at the
measurement positions given in 3) on the next page. It is important to check that not only the ambient
temperatures of the power regeneration common converter but also those of the inverter contained in the same
enclosure fall within the permissible range.
4) Notes on installation surface
The power regeneration common converter will be very hot (maximum about 150°C (302°F)).
The power regeneration common converter (heat sink outside mounting structure model) can be reduced in the
enclosure inside temperature by mounting its heat sink outside the enclosure. Cut the mounting area according
to the panel cutting dimensions. Since the cooling section located outside the enclosure has a cooling fan, do
not use the equipment in the environment that has water drops, oil mists, dust particles, etc. For installation in
an enclosure, use the enclosure inside installation structure model of the power regeneration common
converter and install it on an incombustible (e.g. metal) mounting surface.
Also leave sufficient clearances around the inverter.
5) Avoid high temperature and high humidity.
Avoid direct sunlight and places of high temperature and high humidity.
2
or less)
6) Avoid places where the inverter option is exposed to oil mist, flammable gases, fluff, dust, dirt etc.
Install the inverter option in a clean place or inside a "totally enclosed" panel which does not accept any
suspended matter.
7) Note the cooling method when the power regeneration common converter and inverter is installed in an
enclosure.
When two or more power regeneration common converters and inverters are installed or a ventilation fan is
mounted in an enclosure, the inverters and ventilation fan must be installed in proper positions with extreme
care taken to keep the ambient temperatures of the power regeneration common converters and inverters
below the permissible value. If they are installed in improper positions, the ambient temperatures of the power
regeneration common converters and inverters will rise and ventilation effect will be reduced.
8) Install the power regeneration common converter and inverter securely in the vertical direction with screws or
bolts.
9) Install the dedicated stand-alone reactor (FR-CVL) on horizontal plane. Failure to observe this may lead to
damage of the reactor.

3-phase
AC power supply
Note : 1. Never connect a power supply to the inverter terminals R, S, T.
Such a connection, even if accidental, will damage the inverter
and power regeneration common converter.
2. Match the polarities of the P and N terminals by connecting
terminal P of the inverter to terminal P of the power
regeneration common converter and terminal N of the inverter
to terminal N of the power regeneration common converter as
shown in the connection example. Incorrect matching of
the polarities of the P and N terminals will result in damage
to the inverter.
Do not remove a jumper across terminal P/+ and P1.
3. For the FR-A700, F700, A500, F500 and V500 series, remove
the jumpers across terminals R-R1 and S-S1, and connect
power supply to terminals R1, S1 for the control circuit. For the
FR-E700, D700, E500, S500, C500 and F500J series, the
inverter does not have terminals R1, S1. So you do not need to
make this connection.
4. When wiring the dedicated stand-alone reactor and power
regeneration common converter as well as when wiring
the power supply and terminals R/L11, S/L21, T/MC1, strictly
observe the wiring order as shown in the connection example
(match phase sequence of the power supply).
A wrong connection will damage the power regeneration
common converter.
Do not insert an MCCB nor MC. The power regeneration
common converter functions abnormally.
5. Make sure terminals R/L11, S/L21, T/MC1 are connected to
the power supply. Running the inverter without connecting
these terminals will damage the power regeneration common
converter.
6. Since power to the inverter is supplied by terminals P and N,
set Pr.30 to 2 (for use with a high power factor converter, power
regeneration common converter) for the FR-A700, F700, A500,
F500 and V500 series. This setting disables the built-in brake
resistor.
7. For the FR-A700, F700, E700, D700, A500, F500 and V500
series inverter, assign the X10 signal to any of input terminals to
use the inverter.
8. You can connect up to six inverters to one power regeneration
common converter.
9. Use sink logic (factory setting) when the FR-CV is connected.
The FR-CV cannot be connected when source logic is selected.

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.
Shuts off the inverter output when the power regeneration common converter is
faulty or the converter reset signal is input. Connect to the power regeneration
common converter terminal RDYB. For the FR-A700, F700, E700, D700, A500,
F500 or V500 series, assign the X10 signal to any of the input terminals. For the
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.
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.

Wiring
2.2.2 Wiring of the main circuit
(1) Wiring instructions
1) Crimping terminals with insulation sleeves are recommended for use with the power and inverter cables.
2) Strictly observe the order of wiring in the connection example when performing wiring between the dedicated
stand-alone reactor and power regeneration common converter and wiring between the power supply and
terminals R/L11, S/L21, T/MC1. (Match the phase sequence of the power supply.) Incorrect connection will
damage the power regeneration common converter.
3) Make sure to connect the terminal R/L11, S/L21, T/MC1 to the power supply.
Running the inverter without connecting the terminals will damage the power regeneration common converter.
4) Connect a DC power supply between the power regeneration common converter and inverter with correct
polarity.
5) After wiring, wire off-cuts must not be left in the power regeneration common converter.
Wire off-cuts can cause an alarm, failure or malfunction. Always keep the power regeneration common
converter clean.
When drilling mounting holes in a control box etc., exercise care to prevent chips and other foreign matter from
entering the power regeneration common converter.
6) Electromagnetic wave interference
The input/output (main circuit) of the power regeneration common converter and inverter includes harmonic
components, which may interfere with the communication devices (such as AM radios) used near the power
regeneration common converter and inverter. In this case, install the FR-BIF optional radio noise filter (for use
in the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
7) When rewiring after operation, make sure that the CHARGE lamp has gone off, and when more than 10
minutes have elapsed after power-off, check with a meter that the voltage is zero. After that, start rewiring work.
For some time after power-off, there is a dangerous voltage in the capacitor.
8) Be sure to connect terminal RDY of the FR-CV to the X10 or MRS signal assigned terminal of the inverter, and
connect terminal SE of the FR-CV to terminal SD of the inverter. Without proper connecting, FR-CV will be
damaged.
Notes on Grounding
z To prevent an electric shock, the dedicated stand-alone reactor, power regeneration common converter, inverter and
motor must be grounded.
z Use the dedicated ground terminal to ground the power regeneration common converter. (Do not use the screws in
the case, chassis, etc.)
z Use the reactor mounting screw to earth the dedicated stand-alone reactor.
Use the screw in the marked .
z The ground cable should be as thick as possible. Its gauge should be equal to or larger than those indicated in the
following table. The grounding point should be as near as possible to the power regeneration common converter to
minimize the ground cable length.
