the charged inverter circuits and get an electric shock.
zBefore starting wiring or inspection, switch OFF power,
check to make sure that the operation panel indicator is
OFF, 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.
zThis 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)

400V class inverter in compliance with EN standard.
zAny person who is involved in the wiring or inspection of
this equipment should be fully competent to do the work.
zAlways install the inverter before wiring. Otherwise, you
may get an electric shock or be injured.
zPerform setting dial and key operations with dry hands to
prevent an electric shock. Otherwise you may get 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 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.
z
Install the inverter on a nonflammable wall without holes
(so that nobody can touch 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, switch OFF the inverter
power. A continuous flow of large current could cause a
fire.
zWhen using a brake resistor, make up a sequence that will
turn OFF power when an alarm signal is output.
Otherwise, the brake resistor may excessively overheat
due to damage of the brake transistor and such, causing a
fire.
zDo not connect a resistor directly to the DC terminals +
and -. This could cause a fire.

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 will affect the direction of rotation of the motor.
CAUTION
CAUTION
CAUTION
zBefore starting operation, confirm and adjust the
parameters. A failure to do so may cause some machines
to make unexpected motions.
zWhen you have chosen the retry function, stay away from
the equipment as it will restart suddenly after trip.
zSince pressing key may not stop output depending
on the function setting status, provide a circuit and switch
separately to make an emergency stop (power OFF,
mechanical brake operation for emergency stop, etc).
zMake sure that the start signal is OFF before resetting the
inverter alarm. A failure to do so may restart the motor
suddenly.
z
The load used should be a three-phase induction motor only.
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.
z The 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.
zUse a noise filter to reduce the effect of electromagnetic
interference. Otherwise nearby electronic equipment may
be affected.
zTake measures to suppress harmonics. Otherwise power
supply harmonics from the inverter may heat/damage the
power factor correction capacitor and generator.
zWhen a 400V class motor is inverter-driven, please use an
insulation-enhanced motor or measures taken to
suppress surge voltages. Surge voltages 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,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
zThe inverter can be easily set for high-speed operation.
Before changing its setting, fully examine the
performances of the motor and machine.
zIn addition to the inverter’s holding function, install a
holding device to ensure safety.
zBefore running an inverter which had been stored for a
long period, always perform inspection and test
operation.
zFor prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate
static electricity from your body.

(5) Emergency stop
(6) Maintenance, inspection and parts replacement
(7) Disposal
zProvide a safety backup such as an emergency brake
which will prevent the machine and equipment from
hazardous conditions if the inverter fails.
zWhen the breaker on the inverter input side trips, check
for the wiring fault (short circuit), damage to internal parts
of the inverter, etc. Identify the cause of the trip, then
remove the cause and power ON the breaker.
zWhen any protective function is activated, take the
appropriate corrective action, then reset the inverter, and
resume operation.

1.2 Inverter and peripheral devices
NOTE
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 the FR-BIF optional capacitor
type filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference. (Refer
to page 38).
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
Noise filter
(FR-BSF01, FR-BLF)
Install a noise filter 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.

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.
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The
inverter may be damaged if you do not
use reactors. Select the reactor according
to the model. Remove the jumpers across
terminals + and P1 to connect the DC reactor.
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.
Parameter unit (FR-PU07)
By connecting the connection cable
(FR-CB2) to the PU connector,
operation can be performed from
FR-PU07.

(Refer to page 231)
Inverter (FR-E700)
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
Wrong 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)
(Refer to page 27)
Brake resistor
(FR-ABR, MRS type)
Braking capability can be
improved. (FR-E740-016 or
more, FR-E720S-030 or more)
Always install a thermal relay
when using a brake resistor
whose capacity is 11K or more.

Inverter and peripheral devices
1.2.1 Peripheral devices
Check the inverter type 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 installations in the United States or Canada, use the class T type fuse certified by the UL and cUL.
∗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.
∗4 The power factor may be slightly lower.

Installation of the inverter and enclosure design
1.4 Installation of the inverter and enclosure design
When an inverter panel 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 panel 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 . 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.)
