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.
●Evenif power is off, do not remove the front cover except for wiring orperiodic 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). A neutral-point earthed power supply for 400V class inverter in
compliance with EN standard must be used.
●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. Other-
wise 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 not touch the printed circuit board or handle the cables with wet hands. You may get an
electric shock.
●When 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.
●A PM motor is a synchronous motor with high-performance magnets embedded in the rotor.
Motor terminals holds high-voltage while the motor is running even after the inverter power
is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. In an
application, such as fan and blower, where the motor is driven by the load, a low-voltage
manual motor starter must be connected at the inverter's output side, and wiring and
inspection must be performed while the motor starter is open. Otherwise you may get an
electric shock.

FR-F800 III
Fire Prevention
Injury Prevention
ECAUTION:
●Mount the inverter to incombustible material. Install the inverter on a nonflammable wall
without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mount-
ing 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.
●Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If a
product is used without any inspection, a burst, breakage, or a fire may occur.
ECAUTION:
●Apply only the voltage specified in the instruction manual to each terminal. Otherwise,
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.

Wiring
Operation
ECAUTION:
●Do not install assemblies or components (e. g. power factor correction capacitors) on the
inverter output side, which are not approved from Mitsubishi Electric. These devices on the
inverter output side may be overheated or burn out.
●The direction of rotation of the motor corresponds to the direction of rotation commands
(STF/STR) only if the phase sequence (U, V, W) is maintained.
●PM motor terminals (U, V, W) hold high-voltage while the PM motor is running even after the
power is turned OFF. Before wiring, the PM motor must be confirmed to be stopped. Other-
wise you may get an electric shock.
●Never connect a PM motor to the commercial power supply.
Applying the commercial power supply to input terminals (U,V, W) of a PM motor will burn
the PM motor. The PM motor must be connected with the output terminals (U, V, W) of the
inverter.
PWARNING:
●When you have chosen the retry function, stay away from the equipment as it will restart
suddenly after an alarm stop.
●Since pressing the 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.
●Do not use a PM motor for an application where the PM motor is driven by its load and runs
at a speed higher than the maximum motor speed.
●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 parame-
ters 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.
●Use this inverter only with three-phase induction motors or with a PM motor. 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.

VI
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 theaccepted
EMC procedures for proper installation of frequency inverters. Otherwise nearby electronic
equipment may be affected.
●Take appropriate measures regarding harmonics. Otherwise this can endanger compensa-
tion systems or overload generators.
●When driving a 400 V 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.
●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 inspec-
tion 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.
●Only one PM motor can be connected to an inverter.
●A PM motor must be used under PM motor control. When operating with PM motor control,
a synchronous motor, induction motor or synchronous induction motor may only be used
when it is a PM motor.
●Do not connect a PM motor in the induction motor control settings (initial settings). Do not
use an induction motor under the PM motor control settings. It will cause a failure.
●In the system with a PM motor, the inverter power must be turned ON before closing the
contacts of the contactor at the output side.
●When the emergency drive operation is performed, the operation is continued or the retry is
repeated even when a fault occurs, which may damage or burn the inverter and motor.
Before restarting the normal operation after using the emergency drive function, make sure
that the inverter and motor have no fault.
●In order to protect the inverter and the system against unauthorized access by external
systems via network, take security measures including firewall settings.
●Depending on the network environment, the inverter may not operate as intended due to
delays or disconnection in communication. Carefully consider the conditions and safety for
the inverter on site.

General instructions
Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or par-
tially open. Never run the inverter in this status. Always replace the cover and follow instruction man-
uals when operating the inverter. For more details on the PM motor, refer to the Instruction Manual
of the PM motor.
For details of the inverter FR-F802 (Separated Converter Type) and the corresponding converter unit
FR-CC2 refer to the respective Instruction Manuals (refer to page 1-8).
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 man-
ual, then reset the inverter, and resume operation.
ECAUTION:
●Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It
will cause a failure.
ECAUTION:
●Treat as industrial waste.
