ii
Installation
• Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• 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.
Otherwise, a fire or an accident might result.
• 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 supply, insert a recommended molded case circuit
breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage
circuit breaker (ELCB) (with overcurrent protection) in the path of power lines. Use the
devices within the recommended current range.
• Use wires in the specified size.
• When wiring the inverter to the power supply that is 500 kVA or more, be sure to connect
an optional DC reactor (DCR).
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 output (secondary) circuit.
Doing so could cause fire.
• Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.

iii
• Ensure 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 supply 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.
• Generally, control signal wires are not reinforced insulation. If they accidentally touch any
of live parts in the main circuit, their insulation coat may break for any reasons. In such a
case, an extremely high voltage may be applied to the signal lines. Make a complete
remedy to protect the signal line from contacting any hot high voltage lines.
Doing so could cause an accident or electric shock.
• 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 cover before turning the power ON. Do not remove the
covers while power is applied.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the auto-reset function has been selected, the inverter may automatically restart and
drive the motor depending on the cause of tripping.
(Design the machinery or equipment so that human safety is ensured after restarting.)
• If the stall prevention function (current limiter), automatic deceleration, and overload
prevention control have been selected, the inverter may operate at an
acceleration/deceleration time or frequency different from the commanded ones. Design
the machine so that safety is ensured even in such cases.
Otherwise an accident could occur.

iv
• The key on the keypad is effective only when the keypad operation is enabled with
function code F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an
emergency stop switch separately for safe operations.
Switching the runcommand sourcefrom keypad (local) toexternal equipment (remote) by
turning ON the "Enable communications link" command LE disables the key. To
enable the key foran emergency stop, select the STOP key priority with function code
H96 (= 1 or 3).
• If an alarm reset is made with the Run command signal turned ON, a sudden start will
occur. Ensure that the Run command signal is turned OFF in advance.
Otherwise an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 4 or
5), then the inverter automatically restarts running the motor when the power is recovered.
(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-Multi User's Manual (MEH457), 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.
• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop
inverter operation.
Doing so could cause failure.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• Setting the inverter to highspeeds is easy. Before changingthefrequency(speed) setting,
check the specifications of the motor and machinery.
• The brake function of the inverter does not provide mechanical holding means.
Injuries could occur.

v

GENERAL PRECAUTIONS
Drawings in this manual may be illustrated without covers or safetyshields for explanation of
detail parts. Restore the covers and shields in the original state and observe the description
in the manual before starting operation.

vi
Precautions for use
Driving a 400 V
general-purpose
motor
When driving a 400V general-purpose motor with an inverter
using extremely long wires, damage to the insulation of the
motor may occur. Use an output circuit filter (OFL) if
necessary after checking with the motor manufacturer. Fuji
motors do not require the use of output circuit filters because
of their reinforced insulation.
Torque
characteristics
and temperature
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 decrease the
output torque of the motor.
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-proof rubber 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
motors If the reference 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
approved in advance.
Submersible
motors and
pumps
These motors have a larger rated current than
general-purpose motors. Select an inverter whose rated
output current 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.
Brake motors
For motors equipped with parallel-connected brakes, their
power supply for brake must be supplied from the primary
circuit. If the power supply for brake is connected to the
inverter's output circuit by mistake, the brake will not work.
Do not use inverters for driving motors equipped with
series-connected brakes.
In running
special
motors
Geared motors If the power transmission mechanism uses an oil-lubricated
gearbox or speed changer/reducer, then continuous
operation at low speed may cause poor lubrication. Avoid
such operation.

vii
Synchronous
motors It is necessary to take special measures suitable for this
motor type. Contact your Fuji Electric representative 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
conditions
Installation
location
Use the inverter within the ambient temperature range from
-10 to +50°C.
The heat sink and braking resistor of the inverter may
become 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 overcurrent protection)
in the primary circuit of the inverter to protect the wiring.
Ensure that the circuit breaker rated current is equivalent to
or lower than the recommended rated current.
Installing an MC
in the secondary
circuit
If a magnetic contactor (MC) is mounted in the inverter's
output (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.
Remove the magnet contactor (MC) already installed and
built-in surge killer from the inverter's output (secondary)
circuit before installing the MC to switch the motor power.
Installing an MC
in the primary
circuit
Do not turn the magnetic contactor (MC) inthe primarycircuit
ON or OFF more than once an hour as an inverter failure
may result.
If frequent starts or stops are required during motor
operation, use terminal [FWD]/[REV] signals or the
RUN/STOP key.
Combina-
tion with
peripheral
devices
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
current lower than the set value for the thermal relay. If this
happens, lower the carrier frequency or use the output circuit
filter (OFL).

viii
Discontinuance
of power
capacitor for
power factor
correction
Do not mount power capacitors for power factor correction in
the inverter’s primary circuit. (Use the DC reactor to correct
the inverter power factor.) Do not use power capacitors for
power factor correction in the inverter’s output (secondary)
circuit. An overcurrent trip will occur, disabling motor
operation.
Discontinuance
of surge killer Do not connect a surge killer to the inverter's output (secondary) circuit.
Reducing noise Use of a filter and shielded wires is typically recommendedto
satisfy EMC Directive.
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
current is generated by open/close of the power capacitor for
power factor correction in the power system.
* Connect a DC reactor to the inverter.
Combina-
tion with
peripheral
devices
Megger test When checking the insulation resistance of the inverter, use
a 500 V megger and follow the instructions contained in
Chapter 7, Section 7.5 "Insulation Test."
Control circuit
wiring length
When using remote control, limit the wiring length between
the inverter and operator panel to 20 m or less and use
twisted pair or 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
current value or recommended wire size.
Wiring type When several inverters drive motors, do not use one
multicore cable in order to connect several inverters with
motors.
Wiring
Grounding Securely ground the inverter using the grounding terminal.
Driving
general-purpose
motor
Select an inverter according to the nominal applied motor
rating 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 one rank
larger capacity than the standard.
Selecting
inverter
capacity
Driving special
motors Select an inverter that meets the following condition:
Inverter rated current > Motor rated current
Transpor-
tation and
storage
When transporting or storing inverters, follow the procedures and select locations
that meet the environmental conditions listed in Chapter 1, Section 1.3
"Transportation" and Section 1.4 "Storage Environment."

1.3 Transportation
• When carrying an inverter, always support its bottom at the right and left sides with both hands. Do
not hold covers or individual parts only.
• Avoid applying excessively strong force to the terminal block covers as they are made of plastic
and are easily broken.
1.4 Storage Environment
1.4.1 Temporary storage
Store the inverter in an environment that satisfies the requirements listed in Table 1.1.
Table 1.1 Environmental Requirements for Storage and Transportation
Item Requirements
Storage temperature *1-25 to +70°C
Relative humidity 5 to 95% *2
A location where the inverter is not subject to abrupt changes
in temperature that would result in the formation of
condensation or ice.
Atmosphere The inverter must not be exposed to dust, direct sunlight, corrosive or
flammable gases, oil mist, vapor, water drops or vibration. The atmosphere
must contain only a low level of salt. (0.01 mg/cm2or less per year)
86 to 106 kPa (in storage)Atmospheric pressure 70 to 106 kPa (during transportation)
*1Assuming a comparatively short storage period (e.g., during transportation or the like).
*2Even if the humidity is within the specified requirements, avoid such places where the inverter will be
subjected to sudden changes in temperature that will cause condensation to form.
Precautions for temporary storage
(1) Do not leave the inverter directly on the floor.
(2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight
vinyl sheet or the like for storage.
(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent
(such as silica gel) in the airtight package described in item (2).
1.4.2 Long-term storage
The long-term storage methods for the inverter vary largely according to the environment of the
storage site. General storage methods are described below.
(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the ambient temperature should be within the
range from -10 to +30 °C. This is to prevent the electrolytic capacitors in the inverter from
deteriorating.
(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a
drying agent inside the package to maintain the relative humidity inside the package within 70%.
(3) If the inverter has been installed in the equipment or control panel at a construction site where it
may be subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable
environment specified in Table 1.1.
Precautions for storage over 1 year
If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may
deteriorate. Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not
connect the inverter to a motor or run the motor.

(Note 1) When inverters are mounted
side-by-side without any gap between them
(less than 5.5 kW), the ambient temperature
should be within the range from -10 to +40°C.
(Note 2) Do not install the inverter in an
environment where it may be exposed to
cotton waste or moist dust or dirt which will
clog the heat sink in the inverter. If the
inverter is to be used in such an environment,
install it in the panel of your system or othe
r
dustproof containers.
(Note 3) If you use the inverter in an altitude
above 1000 m, you should apply an outpu
t
current derating factor as listed in Table 2.2.
2.2 Installing the Inverter
(1) Mounting base
The temperature of the heat sink will rise up to approx.
90°C during operation of the inverter, so the inverte
r
should be mounted on a base made of material that can
withstand temperatures of this level.
Install the inverter on a base constructed from metal or
other non-flammable material.
A fire may result with other material.
(2) Clearances
Ensure that the minimum clearances indicated in Figure
2.1 are maintained at all times. When installing the inverte
r
in the panel of your system, take extra care with ventilation
inside the panel as the temperature around the inverte
r
will tend to increase. Do not install the inverter in a small e
panel with poor ventilation.

Required Clearances

When mounting two or more inverters
Horizontal layout is recommended when two or more
inverters are to be installed in the same unit or panel. If it is
necessary to mount the inverters vertically, install a partition
plate or the like between the inverters so that any heat
radiating from an inverter will not affect the one/s above. As
long as the ambient temperature is 40°C or lower, inverters
can be mounted side-by-side without any gap between them
(only for inverters with a capacity of less than 5.5 kW).
When employing external cooling
At the shipment time, the inverter is set up for mount inside
your equipment or panel so that cooling is done all internally.
To improve cooling efficiently, you can take the heat sink out
of the equipment or the panel (as shown on the right) so that
cooling is done both internally and externally (this is called
"external cooling").
In external cooling, the heat sink, which dissipates about
70% of the total heat (total loss) generated into air, is situated
outside the equipment or the panel. As a result, much less
heat is radiated inside the equipment or the panel.
To take advantage of external cooling, you need to use the
external cooling attachment option for inverters with a
capacity of 5.5 kW or above.
In an environment with high humidity or a lot of fibrous dust,
however, do not use external cooling in an environment with
high humidity or a lot of fibrous dust, which tends to clog the
heat sink.
For details, refer to the Mounting Adapter for
External Cooling "PB-F1/E1" Installation Manual
(INR-SI47-0880a).
Figure 2.2 External Cooling
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting
into the inverter or from accumulating on the heat sink.
This may result in a fire or accident.

(3) Mounting direction
Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so
that the logo "FRENIC-Multi" can be seen from the front.
Do not mount the inverter upside down or horizontally. Doing so will reduce the heat
dissipation efficiency of the inverter and cause the overheat protection function to operate,
so the inverter will not run.
(4) Solving abnormal vibration after installation
If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling
fans or the keypad, fix them firmly using the fixing screws provided as accessories.
