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)
Use a neutral-point earthed (grounded) power supply for 400 V class inverter in compliance
with EN standard.
●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 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 1 s at powering off. Never touch the motor terminal, etc. right after powering off to
prevent an electric shock.

FR-E700 SC EC/ENE 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.
●When 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.
●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.

IV

●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 the product on a hot surface.
●The inverter must be installed on a strong surface securely with screws so that it will not drop.
●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.
●During installation, caution must be taken not to drop the inverter as doing so may cause
injuries.
●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.
●If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a
Mitsubishi Electric product, the product will be damaged. Halogen-based materials are
often included in fumigant, which is used to sterilize or disinfect wooden packages. When
packaging, prevent residual fumigant components from being infiltrated into Mitsubishi
Electric products, or use an alternative sterilization or disinfection method (heat disinfec-
tion, etc.) for packaging. Sterilization of disinfection of wooden package should also be
performed before packaging the product.

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. 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.
ECAUTION:
●Before starting operation, confirm and adjust the parameters. A failure to do so may cause
some machines to make unexpected motions.
PWARNING:
●When you have chosen the retry function, stay away from the equipment as the motor 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.
●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.
●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
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.
●Useanoisefilter toreducethe effect ofelectromagnetic interference andfollowthe accepted
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.
●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.
●If you are installing the inverter to drive a three-phase device while you are contracted for
lighting and power service, consult your electric power supplier.
●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.
ECAUTION:
●A safety backup such as an emergency brake must be provided for devices or equipment in
a system to prevent hazardous conditions in case of failure of the inverter or an external
device controlling the inverter.
●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.
