MITSUBISHI ELECTRIC

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.

Wiring

ECAUTION:

●When carrying products, use correct lifting gear to prevent injury.

●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

Operating Condition FR-F740 FR-F746

Ambient temperature −10°C to +40/+50°C (non-freezing) −10°C to +30/+40°C (non-freezing)

The maximum temperature depends on the setting of Pr. 570.

Ambient humidity 90% RH or less (non-condensing)

Storage temperature −20°C to +65°C



Atmosphere Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Altitude Maximum 1000m above sea level for standard operation. After that derate by 3% for

every extra 500m up to 2500m (91%)

commands (STF/STR) only if the phase sequence (U, V, W) is maintained.

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.

MITSUBISHI ELECTRIC

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.
