according to conditions. Please follow the instructions of both levels

because they are important to personnel safety.

1. Electric Shock Prev en tion

• 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 or wiring 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 o ff, do not remove the front cover except for wirin g 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)

shock or be injured.

• 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 not touch the printed circuit board with wet hands. You may get an electric shock.

2. Fire Prevention

• Mount the inverter to incombustible material. 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.

3. Injury Prevention

• 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.

4. Additional Instruc tions

Also note the following points to prevent an accidental failure, injury, electric
shock, etc.

(1) Transporta tion and inst allation

• 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.

• 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.

(2) Wiring

• Do not install a power factor correction capacitor or surge suppressor on the
inverter output side.

• The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.

CAUTION

(3) Test operation and adjustment

• Before starting operation, confirm and adjust the parameters. A failure to do
so may cause some machines to make unexpected motions.

(4) Operation

• When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.

• The key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.

• 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.

• The electronic thermal relay function does not guarantee protection of the
motor from overheating.

• Do not use a magnetic contactor on the inverter input for frequent starting/
stopping of the inverter.

• Use a noise filter to reduce the effect of electromagnetic interference.
Otherwise nearby electronic equipment may be affected.

• Take measures to suppress harmonics. Otherwise power supply harmonics
from the inverter may heat/damage the power factor correction capacitor and
generator.

• When a 400V class motor is inverter-driven, please use an insulation­enhanced 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.

• When parameter clear or all clear is performed, reset 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.

• In addition to the inverter's holding function, install a holding device to ensure
safety.

• 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.

(5) Emergency stop

• Provide a safety backup such as an emergency bra ke which will prevent the
machine and equipment from hazardous conditions if the inverter fails.

• When 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.

• When the protective function is activated, take the corresponding corrective
action, then reset the inverter, and resume operation.

CAUTION

Inverter and peripheral devices

1.1 Inverter and peripheral devices

3-phase AC power supply

Use within the permissible power supply
specifications of the inverter.

(Refer to page 248)

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.

(Refer to page 3)

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.

(Refer to page 3)

Reactor (FR-HAL, FR-HEL)

Reactors (option) should 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 (1000kVA 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 P/+-P1 to
connect to the DC reactor.

(Refer to page 3.)

PLC

RS-485 terminal block

The inverter can be
connected with computers
such as PLC.
It supports Mitsubishi inverter
protocol and Modbus-RTU
(binary) protocol.

Inverter
(FR-F700)

The life of the inverter is influenced by ambient
temperature. The ambient temperature should be as low
as possible within the permiss ible range . Especi ally w hen
mounting the inverter inside an enclosure, take cautions
of the ambient temperature. (Refer to page 27)
Wrong wiring might lead to damage o f the inverter. The

(2) Notes on earthing

 Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed. ((This

inverter must be earthed. Earthing must conform to the requirements of national and local safe ty regulati ons an d el ectric al
codes. (JIS, NEC section 250, IEC 536 c lass 1 and other appl icable st andards)

 Use the dedicated earth terminal to earth the inverter. (Do not use the screw in the casing, chassis, etc.)
 Use the thickest possible earth cable.Use the cable whose size is equal to or greater than that indicated in the

above table, and minimize the cable length. The earthing point should be as near as possible to the inverter.

7

Main circuit terminal specifications

 Always earth the motor and inverter.

1)Purpose of earthingGenerally, an electrical apparatus has an earth terminal, which must be connected to the
ground before use.
An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to
manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current
flow into the case. The purpose of earthing the case of an electrical apparatus is to prevent operator from
getting an electric shock from this leakage current when touching it.
To avoid the influence of external noises, this earthing is important to audio equipment, sensors, computers and
other apparatuses that handle low-level signals or operate very fast.

2)Earthing methods and earthing work
As described previously, earthing is roughly classified into an electrical shock prevention type and a noise­affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the
following work must be done to prevent the leakage current having the inverter's high frequency components
from entering the malfunction prevention type earthing:
(a) Where possible, use independent earthing for the inverter. If independent earthing (I) is impossible, use

joint earthing (II) where the inverter is connected with the other equipment at an earthing point. Joint
earthing as in (III) must be avoided as the inverter is connected with the other equipment by a common
earth cable.
Also a leakage current including many high frequency components flows in the earth cables of the inverter
and inverter-driven motor. Therefore, they must use the independent earthing method and be separated
from the earthing of equipment sensitive to the aforementioned noises.
In a tall building, it will be a good policy to use the noise malfunction prevention type earthing with steel
frames and carry out electric shock prevention type earthing in the independent earthing method.

(b) 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).

(c) Use the thickest possible earth cable. The earth cable should be of not less than the size indicated in the

above table.

(d) The grounding point should be as near as possible to the inverter, and the ground wire length should be as

short as possible.

(e) Run the earth cable as far away as possible from the I/O wiring of equipment sensitive to noises and run

them in parallel in the minimum distance.

Control circuit specifications

(2) Common terminals of the control circuit (PC, 5, SE)

Terminals PC, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other.
Terminal PC is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS,
RES, AU, CS).
The open collector circuit is isolated from the internal control circuit by photocoupler.
Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4), analog current output terminal (CA)
and analog output terminal AM.
It should be protected from external noise using a shielded or twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN, SU, OL, IPF, FU).
The contact input circuit is isolated from the internal control circuit by photocoupler.

(3) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR, STOP,
RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled
using a transistor instead of a contacted switch as shown on the
