Japanese Guideline for Suppressing Harmonics in Home Electric and Gen-
eral-purpose Appliances
Fuji Electric's three-phase, 200 V series inverters of 3.7 (4.0) kW or less (FRENIC-Mini series) are
the products specified in the "Japanese Guideline for Suppressing Harmonics in Home Electric
and General-purpose Appliances" (established in September 1994 and revised in October 1999),
published by the Ministry of International Trade and Industry (currently the Ministry of Economy,
Trade and Industry (MITI)). The Japan Electrical Manufacturers' Association (JEMA) has deter-
mined a standard of regulation levels based on this guideline. To meet this standard, a reactor (for
harmonic suppression) must be connected to an inverter. Please use one of the DC reactors listed
in this manual. If you need to prepare a reactor yourself, however, please consult Fuji Electric.

• FRENIC-Mini may not be used for a life-support system or other purposes directly re-
lated to the human safety.
• Though FRENIC-Mini is manufactured under strict quality control, install safety devices
for applications where serious accidents or material losses are foreseen in relation to the
failure of it.
An accident could occur.
Installation
• Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.
• Do not place flammable matter nearby.
Doing so could cause fire.

iii
• Do not support the inverter by its terminal block cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from
getting into the inverter or from accumulating on the heat sink.
Doing so could cause fire or an accident.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
• Do not get on a shipping box.
• Do not stack shipping boxes higher than the indicated information printed on those
boxes.
Doing so could cause injuries.
Wiring
• When wiring the inverter to the power source, insert a recommended molded case circuit
breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage cir-
cuit breaker (ELCB) (with the exception of those exclusively designed for protection from
ground faults) in the path of power lines. Use the devices within the related current
range.
• Use wires in the specified size.
Otherwise, fire could occur.
• Do not use one multicore cable in order to connect several inverters with motors.
• Do not connect a surge killer to the inverter's secondary circuit.
Doing so could cause fire.
• Be sure to connect the grounding wires without fail.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power off.
• Ground the inverter according to the requirements of your national and local safety
regulations.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.
• Check that the number of input phases and the rated voltage of the product match the
number of phases and the voltage of the AC power supply to which the product is to be
connected.
Otherwise fire or an accident could occur.
• Do not connect the power source wires to output terminals (U, V, and W).
• Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+)
and P1, DB and N (-), or P1 and DB.
Doing so could cause fire or an accident.

iv
• Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases
each other.
Otherwise injuries could occur.
• The inverter, motor and wiring generate electric noise. Take care of malfunction of the
nearby sensors and devices. To prevent the motor from malfunctioning, implement noise
control measures.
Otherwise an accident could occur.
Operation
• Be sure to install the terminal block cover before turning the power on. Do not remove
the cover during power application.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the retry function has been selected, the inverter may automatically restart and drive
the motor according to some causes after tripping.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If the stall prevention function has been selected, the inverter may operate at an accel-
eration/deceleration time or frequency different from the set ones. Design the machine
so that safety is ensured even in such cases.
Otherwise an accident could occur.
• The STOP key is only effective when function setting (Function code F02) has been es-
tablished to enable the STOP key. Prepare an emergency stop switch separately. If you
disable the STOP key priority function and enable command (FWD) or (REV), you can-
not stop the inverter output by the STOP key on the built-in keypad.
• If an alarm reset is made with the operation signal turned on, a sudden start will occur.
Check that the operation signal is turned off in advance.
Otherwise an accident could occur.
• If you enable the "restart mode after instantaneous power failure" (Function code F14 =
4 or 5), then the inverter automatically restarts running the motor when the power is re-
covered.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If you set the function codes wrongly or without completely understanding this instruction
manual and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a
speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the
inverter stops.
Doing so could cause electric shock.

v
• Do not turn the main circuit power on or off in order to start or stop inverter operation.
Doing so could cause failure.
• Do not touch the heat sink or braking resistor because they become very hot.
Doing so could cause burns.
• Setting the inverter to high speeds is easy. Check the specifications of the motor and
machinery before changing the setting.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.

in the manual before starting operation.

vi
Conformity to the Low Voltage Directive in the EU
If installed according to the guidelines given below, inverters marked with CE or TÜV are consid-
ered as compliant with the Low Voltage Directive 73/23/EEC.
1. The ground terminal G should always be connected to the ground. Do not use only a
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)*
as the sole method of electric shock protection. Be sure to use ground wires whose size is
greater than power supply lines.
*With the exception of those exclusively designed for protection from ground faults.
2. When used with the inverter, a molded case circuit breaker (MCCB), residual-current-
operated protective device (RCD)/earth leakage circuit breaker (ELCB) or magnetic con-
tactor (MC) should conform to the EN or IEC standards.
3. When you use a residual-current-operated protective device (RCD)/earth leakage circuit
breaker (ELCB) for protection from electric shock in direct or indirect contact power lines
or nodes, be sure to use type B of RCD/ELCB at the power supply side of the electric
equipment for three-phase 200/400 V power supplies. For single-phase 200 V power sup-
plies, use type A.
When you use no RCD/ELCB, take any other protective measure that isolates the electric
equipment from other equipment on the same power supply line using double or rein-
forced insulation or that isolates the power supply lines connected to the electric equip-
ment using an isolation transformer.
4. The inverter should be used in an environment that does not exceed Pollution Degree 2
requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in
an enclosure of IP54 or higher.
5. Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum
degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can
be easily accessed), to prevent human body from touching directly to live parts of these
equipment.
6. To make an inverter with no integrated EMC filter conform to the EMC directive, it is nec-
essary to connect an external EMC filter to the inverter and install them properly so that
the entire equipment including the inverter conforms to the EMC directive.
7. Do not connect any copper wire directly to grounding terminals. Use crimp terminals with
tin or equivalent plating to connect them.
8. To connect the three-phase or single-phase 200 V series of inverters to the power supply
in Overvoltage Category III or to connect the 3-phase 400 V series of inverters to the
power supply in Overvoltage Category II or III, a supplementary insulation is required for
the control circuitry.
9. When you use an inverter at an altitude of more than 2000 m, you should apply basic in-
sulation for the control circuits of the inverter. The inverter cannot be used at altitudes of
more than 3000 m.
10. The power supply mains neutral has to be earthed for the three-phase 400 V class
inverter.

Precautions for use
Driving a 400V
general-purpose
motor
When driving a 400V general-purpose motor with an
inverter using extremely long wires, damage to the insula-
tion of the motor may occur. Use an output circuit filter
(OFL) if necessary after checking with the motor manufac-
turer. Fuji's motors do not require the use of output circuit
filters because of their reinforced insulation.
Torque charac-
teristics and tem-
perature rise
When the inverter is used to run a general-purpose motor,
the temperature of the motor becomes higher than when it
is operated using a commercial power supply. In the low-
speed range, the cooling effect will be weakened, so de-
crease the output torque of the motor. If constant torque is
required in the low-speed range, use a Fuji inverter motor or
a motor equipped with an externally powered ventilating fan.
Vibration
When an inverter-driven motor is mounted to a machine,
resonance may be caused by the natural frequencies of the
machine system.
Note that operation of a 2-pole motor at 60 Hz or higher
may cause abnormal vibration.
* The use of a rubber coupling or vibration dampening rub-
ber is recommended.
* Use the inverter's jump frequency control feature to skip
the resonance frequency zone(s).
In running
general-
purpose
motors
Noise
When an inverter is used with a general-purpose motor, the
motor noise level is higher than that with a commercial
power supply. To reduce noise, raise carrier frequency of the
inverter. Operation at 60 Hz or higher can also result in
higher noise level.
High-speed mo-
tors
If the set frequency is set to 120 Hz or more to drive a high-
speed motor, test-run the combination of the inverter and
motor beforehand to check for safe operation.
Explosion-proof
motors
When driving an explosion-proof motor with an inverter, use
a combination of a motor and an inverter that has been ap-
proved in advance.
Submersible
motors and
pumps
These motors have a larger rated current than general-
purpose motors. Select an inverter whose rated output cur-
rent is greater than that of the motor.
These motors differ from general-purpose motors in thermal
characteristics. Set a low value in the thermal time constant
of the motor when setting the electronic thermal function.
In running
special
motors
Brake motors
For motors equipped with parallel-connected brakes, their
braking power must be supplied from the primary circuit. If
the brake power is connected to the inverter's power output
circuit by mistake, the brake will not work.
Do not use inverters for driving motors equipped with series-
connected brakes.

xi
Geared motors
If the power transmission mechanism uses an oil-lubricated
gearbox or speed changer/reducer, then continuous motor
operation at low speed may cause poor lubrication. Avoid
such operation.
Synchronous mo-
tors It is necessary to take special measures suitable for this
motor type. Contact Fuji for details.
In running
special
motors
Single-phase
motors
Single-phase motors are not suitable for inverter-driven
variable speed operation. Use three-phase motors.
* Even if a single-phase power supply is available, use a
three-phase motor as the inverter provides three-phase
output.
Environ-
mental con-
ditions
Installation loca-
tion
Use the inverter within the ambient temperature range from
-10 to +50C.
The heat sink and braking resistor of the inverter may be-
come hot under certain operating conditions, so install the
inverter on nonflammable material such as metal.
Ensure that the installation location meets the environmental
conditions specified in Chapter 2, Section 2.1 "Operating
Environment."
Installing an
MCCB or
RCD/ELCB
Install a recommended molded case circuit breaker (MCCB)
or residual-current-operated protective device (RCD)/earth
leakage circuit breaker (ELCB) (with the exception of those
exclusively designed for protection from ground faults) in the
primary circuit of the inverter to protect the wiring. Ensure
that the circuit breaker capacity is equivalent to or lower
than the recommended capacity.
Installing an MC
in the secondary
circuit
If a magnetic contactor (MC) is mounted in the inverter's
secondary circuit for switching the motor to commercial
power or for any other purpose, ensure that both the
inverter and the motor are completely stopped before you
turn the MC on or off.
Do not connect a magnet contactor united with a surge killer
to the inverter's secondary circuit.
Installing an
MC in the pri-
mary circuit
Do not turn the magnetic contactor (MC) in the primary cir-
cuit on or off more than once an hour as an inverter fault
may result.
If frequent starts or stops are required during motor opera-
tion, use FWD/REV signals or the RUN/STOP key.
Combina-
tion with pe-
ripheral de-
vices
Protecting the
motor
The electronic thermal function of the inverter can protect
the motor. The operation level and the motor type (general-
purpose motor, inverter motor) should be set. For high-
speed motors or water-cooled motors, set a small value for
the thermal time constant and protect the motor.
If you connect the motor thermal relay to the motor with a
long wire, a high-frequency current may flow into the wiring
stray capacitance. This may cause the relay to trip at a cur-
rent lower than the set value for the thermal relay. If this
happens, lower the carrier frequency or use the output cir-
cuit filter (OFL).

xii
Discontinuance
of power-factor
correcting ca-
pacitor
Do not mount power-factor correcting capacitors in the
inverter primary circuit. (Use the DC reactor to improve the
inverter power factor.) Do not use power-factor correcting
capacitors in the inverter output circuit. An overcurrent trip
will occur, disabling motor operation.
Discontinuance
of surge killer
Do not connect a surge killer to the inverter's secondary cir-
cuit.
Reducing noise Use of a filter and shielded wires is typically recommended
to satisfy EMC directives.
Combina-
tion with pe-
ripheral de-
vices
Measures against
surge currents
If an overvoltage trip occurs while the inverter is stopped or
operated under a light load, it is assumed that the surge cur-
rent is generated by open/close of the phase-advancing ca-
pacitor in the power system.
* Connect a DC reactor to the inverter.
Megger test
When checking the insulation resistance of the inverter, use
a 500 V megger and follow the instructions contained in
Chapter 7, Section 7.4 "Insulation Test."
Control circuit
wiring length
When using remote control, limit the wiring length between
the inverter and operator box to 20 m or less and use
twisted shielded wire.
Wiring length
between inverter
and motor
If long wiring is used between the inverter and the motor,
the inverter will overheat or trip as a result of overcurrent
(high-frequency current flowing into the stray capacitance) in
the wires connected to the phases. Ensure that the wiring is
shorter than 50 m. If this length must be exceeded, lower
the carrier frequency or mount an output circuit filter (OFL).
Wiring size Select wires with a sufficient capacity by referring to the cur-
rent value or recommended wire size.
Wiring
Wiring type Do not use one multicore cable in order to connect several
inverters with motors.
Grounding Securely ground the inverter using the grounding terminal.
Selecting
inverter
capacity Driving general-
purpose motor
Select an inverter according to the applicable motor ratings
listed in the standard specifications table for the inverter.
When high starting torque is required or quick acceleration
or deceleration is required, select an inverter with a capacity
one size greater than the standard.
Transpor-
tation and
storage
Driving special
motors
Select an inverter that meets the following condition:
