Electric shock prevention
PWARNING:
●While power is on or when the inverter is running, do not open the front cover.
Otherwise you may get an electric shock.
●Do not run the inverter with the front cover removed. Otherwise, you may access
the exposed high-voltage terminals or the charging part of the circuitry and get an
electric shock.
●Even if power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric shock.
●Before starting wiring or inspection, 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.
●This inverter must be earthed. Earthing must conform to the requirements of
national and local safety regulations and electrical codes. (JIS, NEC section 250,
IEC 536 class 1 and other applicable standards)
●Any person who is involved in the wiring or inspection of this equipment should
be fully competent to do the work.
●Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
●If your application requires by installation standards an RCD (residual current
device) as up stream protection please select according to DIN VDE 0100-530 as
following:
Single phase inverter type A or B
Three phase inverter only type B.
●Perform setting dial and key operations with dry hands to prevent an electric shock.
Otherwise you may get an electric shock. Perform setting dial and key operations
with dry hands to prevent an electric shock. Otherwise you may get an electric
shock.
●Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise you may get an electric shock.
●Do not replace the cooling fan while power is on. It is dangerous to replace the
cooling fan while power is on.
●Do no
t touch the printed circuit board or handle the cables with wet hands. You may get
an electric shock.

FR-F700 EC III
Fire prevention
Injury prevention
ECAUTION:
●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 combustible
material can cause a fire.
●If the inverter has become faulty, switch off the inverter power. A continuous flow
of large current could cause a fire.
●Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a
fire and destroy the inverter. The surface temperature of braking resistors can far
exceed 100°C for brief periods. Make sure that there is adequate protection against
accidental contact and a safe distance is maintained to other units and system
parts.
ECAUTION:
●Apply only the voltage specified in the instruction manual to each terminal. Other-
wise, burst, damage, etc. may occur.
●Ensure that the cables are connected to the correct terminals. Otherwise, burst,
damage, etc. may occur.
●Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst,
damage, etc. may occur.
●While power is on or for some time after power-off, do not touch the inverter as it
is hot and you may get burnt.

●Do not stack the inverter boxes higher than the number recommended.
●Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
●Do not install or operate the inverter if it is damaged or has parts missing. This can
result in breakdowns.
●When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
●Do not stand or rest heavy objects on the product.
●Check the inverter mounting orientation is correct.
●Prevent other conductive bodies such as screws and metal fragments or other
flammable substance such as oil from entering the inverter.
●As the inverter is a precision instrument, do not drop or subject it to impact.
●Use the inverter under the following environmental conditions. Otherwise, the
inverter may be damaged

FR-F700 EC V
Operation
PWARNING:
●When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
●Since pressing STOP/RESET 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.).
●Make sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
●The inverter can be started and stopped via the serial port communications link or
the field bus. However, please note that depending on the settings of the
communications parameters it may not be possible to stop the system via these
connections if there is an error in the communications system or the data line. In
configurations like this it is thus essential to install additional safety hardware that
makes it possible to stop the system in an emergency (e.g. controller inhibit via
control signal, external motor contactor etc). Clear and unambiguous warnings
about this must be posted on site for the operating and service staff.
●The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the inverter as well
as the equipment.
●Do not modify the equipment.
●Do not perform parts removal which is not instructed in this manual. Doing so may
lead to fault or damage of the inverter.

Diagnosis and settings
Emergency stop
ECAUTION:
●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.
●Do not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter. Otherwise, the life of the inverter decreases.
●Use a noise filter to reduce the effect of electromagnetic interference and follow
the accepted EMC procedures for proper installation of frequency inverters. Oth-
erwise nearby electronic equipment may be affected.
●Take appropriate measures regarding harmonics. Otherwise this can endanger
compensation systems or overload generators.
●Use a motor designed for inverter operation. (The stress for motor windings is
bigger than in line power supply).
●When parameter clear or all clear is performed, set again the required parameters
before starting operations. Each parameter returns to the initial value.
●The inverter can be easily set for high-speed operation. Before changing its setting,
fully examine the performances of the motor and machine.
●The DC braking function of the frequency inverter is not designed to continuously
hold a load. Use an electro-mechanical holding brake on the motor for this purpose.
●Before running an inverter which had been stored for a long period, always perform
inspection and test operation.
●For prevention of damage due to static electricity, touch nearby metal before
touching this product to eliminate static electricity from your body.
ECAUTION:
●Before starting operation, confirm and adjust the parameters. A failure to do so
may cause some machines to make unexpected motions.
ECAUTION:
●Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
●When the breaker on the inverter primary 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.
●When the protective function is activated (i. e. the frequency inverter switches off
with an error message), take the corresponding corrective action as described in
the inverter manual, then reset the inverter, and resume operation.
