4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.
(1) Transportation and Mounting
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the Instruction Manual
and appended documents carefully and can use the
equipment correctly. Do not use this product until you have
a full knowledge of the equipment, safety information and
instructions.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION".
Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.
zWhile power is ON or when the inverter is running, do not
open the front cover. Otherwise you may get an electric
shock.
zDo not run the inverter with the front cover or wiring cover
removed. Otherwise you may access the exposed high-
voltage terminals or the charging part of the circuitry and
get an electric shock.
zEven if power is OFF, do not remove the front cover
except for wiring or periodic inspection. You may
accidentally touch the charged inverter circuits and get an
electric shock.
zBefore wiring or inspection, power must be switched OFF.
To confirm that, LED indication of the operation panel
must be checked. (It must be OFF.) Any person who is
involved in wiring or inspection shall wait for at least 10
minutes after the power supply has been switched OFF
and check that there are no residual voltage using a tester
or the like. The capacitor is charged with high voltage for
some time after power OFF, and it is dangerous.
z This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code (NEC section
250, IEC 536 class 1 and other applicable standards).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
zAny person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
zThe inverter must be installed before wiring. Otherwise
you may get an electric shock or be injured.
zSetting dial and key operations must be performed with
dry hands to prevent an electric shock.
zDo not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an
electric shock.
zDo not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
zDo not touch the printed circuit board or handle the
cables with wet hands. Otherwise you may get an electric
shock.
zWhen measuring the main circuit capacitor capacity, the
DC voltage is applied to the motor for 1s at powering OFF.
Never touch the motor terminal, etc. right after powering
OFF to prevent an electric shock.
WARNING
CAUTION
CAUTION
WARNING
zInverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the
rear side, etc.). Mounting it to or near flammable material
can cause a fire.
zIf the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
zWhen using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly cause a fire.
zDo not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
zThe voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
zThe cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
zPolarity must be correct. Otherwise burst, damage, etc.
may occur.
zWhile power is ON or for some time after power-OFF, do
not touch the inverter as they will be extremely hot. Doing
so can cause burns.
zThe product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to
injuries.
zDo not stack the boxes containing inverters higher than
the number recommended.
zThe product must be installed to the position where
withstands the weight of the product according to the
information in the Instruction Manual.
zDo not install or operate the inverter if it is damaged or
has parts missing.
zWhen carrying the inverter, do not hold it by the front
cover or setting dial; it may fall off or fail.
zDo not stand or rest heavy objects on the product.
zThe inverter mounting orientation must be correct.
zForeign conductive objects must be prevented from
entering the inverter. That includes screws and metal
fragments or other flammable substance such as oil.
zAs the inverter is a precision instrument, do not drop or
subject it to impact.
zThe inverter must be used under the following
environment. Otherwise the inverter may be damaged.

(6) Maintenance, inspection and parts replacement
(7) Disposal
zDo not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side. These devices on the inverter output side may be
overheated or burn out.
zThe connection orientation of the output cables U, V, W to
the motor affects the rotation direction of the motor.
zBefore starting operation, each parameter must be
confirmed and adjusted. A failure to do so may cause
some machines to make unexpected motions.
zAny person must stay away from the equipment when the
retry function is set as it will restart suddenly after trip.
zSince pressing key may not stop output depending
on the function setting status, separate circuit and switch
that make an emergency stop (power OFF, mechanical
brake operation for emergency stop, etc.) must be
provided.
zOFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with
the start signal ON restarts the motor suddenly.
z
The inverter must be used for three-phase induction motors.
Connection of any other electrical equipment to the
inverter output may damage the equipment.
zDo not modify the equipment.
z
Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
zThe electronic thermal relay function does not guarantee
protection of the motor from overheating. It is
recommended to install both an external thermal and PTC
thermistor for overheat protection.
zDo not use a magnetic contactor on the inverter input for
frequent starting/stopping of the inverter. Otherwise the
life of the inverter decreases.
zThe effect of electromagnetic interference must be
reduced by using a noise filter or by other means.
Otherwise nearby electronic equipment may be affected.
zAppropriate measures must be taken to suppress
harmonics. Otherwise power supply harmonics from the
inverter may heat/damage the power factor correction
capacitor and generator.
zWhen driving a 400V class motor by the inverter, the
motor must be an insulation-enhanced motor or measures
must be taken to suppress surge voltage. Surge voltage
attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
zWhen parameter clear or all parameter clear is performed,
the required parameters must be set again before starting
operations because all parameters return to the initial value.
zThe inverter can be easily set for high-speed operation.
Before changing its setting, the performances of the
motor and machine must be fully examined.
zStop status cannot be hold by the inverter's brake
function. In addition to the inverter’s brake function, a
holding device must be installed to ensure safety.
zBefore running an inverter which had been stored for a long
period, inspection and test operation must be performed.
zFor prevention of damage due to static electricity, nearby
metal must be touched before touching this product to
eliminate static electricity from your body.
CAUTION
CAUTION
WARNING
CAUTION
zA safety backup such as an emergency brake must be
provided to prevent hazardous condition to the machine
and equipment in case of inverter failure.
zWhen the breaker on the inverter input side trips, the
wiring must be checked for fault (short circuit), and
internal parts of the inverter for a damage, etc. The cause
of the trip must be identified and removed before turning
ON the power of the breaker.
zWhen any protective function is activated, appropriate
corrective action must be taken, and the inverter must be
reset before resuming operation.
zDo not carry out a megger (insulation resistance) test on
the control circuit of the inverter. It will cause a failure.
zThe inverter must be treated as industrial waste.

Inverter and peripheral devices
1.2 Inverter and peripheral devices
NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as
possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer
to page 8)
yWrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit
to protect them from noise. (Refer to page 14)
Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are
connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, install options among the capacitor type
EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC
filter to minimize the interference. (Refer to page 44).
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
EMC filter (ferrite core)
(FR-BSF01, FR-BLF)
Install an EMC filter (ferrite core)
to reduce the electromagnetic
noise generated from the inverter.
Effective in the range from about
1MHz to 10MHz. A wire should be
wound four turns at a maximum.
Motor
Earth (Ground)
Earth (Ground)
Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or capacitor type filter on the output
side of the inverter. When installing a moulded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
moulded case circuit breaker.
The regenerative braking capability
of the inverter can be exhibited fully.
Install this as required.

AC power supply
Use within the permissible power supply
specifications of the inverter. To ensure
safety, use a moulded case circuit breaker,
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the inverter. Doing so will
cause the inverter life to be shorten.
Moulded case circuit breaker
(MCCB) or earth leakage circuit
breaker (ELB), fuse
The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.
Install an EMC filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.
To prevent an electric shock, always earth (ground)
the motor and inverter. For reduction of induction noise
from the power line of the inverter, it is recommended
to wire the earthing cable by returning it to the earth
(ground) terminal of the inverter.

Inverter and peripheral devices
1.2.1 Peripheral devices
Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices:
∗1 Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
∗2 For the use in the United States or Canada, select a UL and cUL certified fuse with Class T fuse equivalent cut-off
speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489 molded case circuit breaker (MCCB).
( Refer to the Installation Guideline)
∗3 Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with class
AC-3 rated current for the motor rated current.
∗5 The power factor may be slightly lower.
∗6 Single-phase 100V power input model is not compatible with DC reactor.

Installation of the inverter and enclosure design
1.4 Installation of the inverter and enclosure design
When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the
environment of an operating place, and others must be fully considered to determine the enclosure structure, size and
equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of
operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.
1.4.1 Inverter installation environment
As the inverter installation environment should satisfy the standard specifications indicated in the following table, operation in
any place that does not meet these conditions not only deteriorates the performance and life of the inverter, but also causes a
failure. Refer to the following points and take adequate measures.
(1) Temperature
The permissible surrounding air temperature of the inverter is between -10 and +50 ° C (14 ° F to 122 ° F). Always operate the
inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the
semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the
inverter falls within the specified range.
1) Measures against high temperature
Use a forced ventilation system or similar cooling system. (Refer to page 10)
Install the panel in an air-conditioned electrical chamber.
Block direct sunlight.
Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.
Ventilate the area around the panel well.
2) Measures against low temperature
Provide a space heater in the enclosure.
Do not power off the inverter. (Keep the start signal of the inverter off.)
3) Sudden temperature changes
Select an installation place where temperature does not change suddenly.
Avoid installing the inverter near the air outlet of an air conditioner.
If temperature changes are caused by opening/closing of a door, install the inverter away from the door.
(2) Humidity
Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of
reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The
insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.
1) Measures against high humidity
Make the panel enclosed, and provide it with a hygroscopic agent.
Take dry air into the enclosure from outside.
Provide a space heater in the enclosure.
2) Measures against low humidity
What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)
beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into
the panel from outside.
3) Measures against condensation
Condensation may occur if frequent operation stops change the in-panel temperature suddenly or if the outside-air
temperature changes suddenly.
Condensation causes such faults as reduced insulation and corrosion.
Take the measures against high humidity in 1).
Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

OUTLINE
Installation of the inverter and enclosure design
(3) Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to
moisture absorption of accumulated dust and dirt, and in-panel temperature rise due to clogged filter. In the atmosphere
where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in
a short time.
Since oil mist will cause similar conditions, it is necessary to take adequate measures.
Countermeasures
Place in a totally enclosed enclosure.
Take measures if the in-enclosure temperature rises. (Refer to page 10)
Purge air.
Pump clean air from outside to make the in-panel pressure higher than the outside-air pressure.
(4) Corrosive gas, salt damage
If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the
relays and switches will result in poor contact.
In such places, take the measures given in Section 3.
(5) Explosive, flammable gases
As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may be
caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has
passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to avoid
installation in such places and install the inverter in a non-hazardous place.
(6) Highland
Use the inverter at the altitude of within 1000m (3280.80 feet). If it is used at a higher place, it is likely that thin air will reduce
the cooling effect and low air pressure will deteriorate dielectric strength.
(7) Vibration, impact
The vibration resistance of the inverter is up to 5.9m/s2at 10 to 55Hz frequency and 1mm amplitude for the directions of X, Y,
Z axes. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause
poor contact to the connectors.
Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.
Countermeasures
Provide the panel with rubber vibration isolators.
Strengthen the structure to prevent the panel from resonance.
Install the panel away from sources of vibration.

1.4.2 Cooling system types for inverter panel
From the panel that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.)
and the incoming heat such as direct sunlight must be dissipated to keep the in-panel temperature lower than the permissible
temperatures of the in-panel equipment including the inverter.
The cooling systems are classified as follows in terms of the cooling calculation method.
1) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)
2) Cooling by heat sink (aluminum fin, etc.)
3) Cooling by ventilation (forced ventilation type, pipe ventilation type)
4) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)
Cooling System Panel Structure Comment
Natural
cooling
Natural ventilation
(enclosed, open type)
Low in cost and generally used, but the panel size increases
as the inverter capacity increases. For relatively small
capacities.
Natural ventilation
(totally enclosed type)
Being a totally enclosed type, the most appropriate for hostile
environment having dust, dirt, oil mist, etc. The panel size
increases depending on the inverter capacity.
Forced
cooling
Fin cooling Having restrictions on the heatsink mounting position and
area, and designed for relative small capacities.
Forced ventilation For general indoor installation. Appropriate for panel
downsizing and cost reduction, and often used.
Heat pipe Totally enclosed type for panel downsizing.

Installation of the inverter and enclosure design
1.4.3 Inverter placement
(1) Installation of the inverter
Enclosure surface mounting
Remove the front cover and wiring cover to fix the inverter to the surface.
(2) Clearances around inverter
(3) Inverter mounting orientation
Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.
NOTE
When encasing multiple inverters, install them in parallel as a
cooling measure.
Install the inverter vertically.
To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter. At least the
following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space.

* When using the inverters at the surrounding air
temperature of 40 C (
104 F) or less, the inverters
can be installed without any clearance between them
(0cm (
0inch) clearance).
When surrounding air temperature exceeds 40 C
(
104 F) , clearances between the inverters should be
1cm
