This section is specifically about safety matters
Do not attempt to install, oper ate, maintain or inspect the
inverter until you have read through the Instruction Manual
(Basic) and appended documents carefully and can use the
equipment correctly. Do not use this product until you have a
full knowledge of the equipment, safety information and
instructions.
In this Instruction Manual (Basic), the safety instruction
levels are classified i nto "WARNING" and "CAUTION".
The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.
1. Electric Shock Prevention
While the inverter powe r is ON, do not remove th e front
cover or the wiring cover. Do not run the inverter with the
front cover or the 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 OFF, do not remove the front cover except
for wiring or periodic inspection. You may accidentally
touch the charged inverter circuits and get an electric
shock.
Before wiring or in spection, power must be switched OFF.
To confirm that, LED indication of the operation panel must
be checked. (It must be OFF.) Any person who is involved
in wiring or inspection s hall 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 (grounded). Earthing
(grounding) must conform t o the requirements of national and
local safety regulations and electrical code (NEC section 250,
IEC 61140 class 1 and other applicable standards).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
Any person who is inv olved in wiring or inspe ction of this
equipment shall be fully competent to do the work.
The inverter must be installed before wiring. Otherwise you
may get an electric shock or be injured.
Setting dial and key operations must be performed with dry
hands to prevent 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 change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
Do not touch the printed circuit board or handle the cables
with wet hands. Otherwise 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.
Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
2. Fire Prevention
Inverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the
rear side, etc.). Mounting it to or near flammable material
can cause a fire.
If the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly cause a fire.
Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
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.
3. Injury Prevention
The voltage applied to each terminal must be the ones
specified in the Instruct ion Manual. Otherwise bur st,
damage, etc. may occur.
The cables must be connected to the correct terminals.
Otherwise burst, damage, etc . may occur.
Polarity must be corr ect. Otherwise burst , damage, etc.
may occur.
While power is ON or for some time after power-OFF, do not
touch the inverter as they will be extremely hot. Doing so
can cause burns.
4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.
(1) Transportation and Mounting
The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to
injuries.
Do not stack the boxes containing inverters higher than
the number recommended.
The product must be installed to the position where
withstands the weight of the product 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.
The inverter mounting orientation must be correct.
Foreign conductive objects must be prevented from
entering the inverter. That includes screws and metal
fragments or other flammable substance such as oil.
As the inverter is a precision instrument, do not drop or
subject it to impact.
The inverter must be used under the following
environment. Otherwise the inverter may be damaged.
Surrounding air

Temperature applicable for a short time, e.g. in transit.
If halogen-based ma terials (fluorine, ch lorine, bromine,
iodine, etc.) infiltrate into a Mitsubishi Electric pr oduct, the
product will be damaged. Halogen-based materials are often
included in fumigant, which is used to ster ilize or disinfest
wooden packages. When packaging, prevent residual
fumigant components from being infiltrated into Mitsubishi
Electric products, or use an alternative sterilization or
disinfection method (heat disinfection, etc.) for packaging.
Sterilization of disinfection of wooden package should also
be performed before packaging the product.

CAUTION
CAUTION
WARNING
CAUTION
CAUTION
CAUTION
CAUTION
Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output side.
These devices on the inverter output side may be
overheated or burn out.
The connection orientation of the output cables U, V, W to
the motor affects the rotation direction of the motor.
(3) Trial run
Before starting operation, each parameter must be
confirmed and adjusted. A failure to do so may cause some
machines to make unexpected motions.
(4) Usage
Any person must stay away from the equipment when the
retry function is set as it will restart suddenly after trip.
Since pressing key may not stop output depending
on the function setting status, separate circuit and switch
that make an emergency stop (power OFF, mechanical
brake operation for emergency stop, etc.) must be
provided.
OFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with
the start signal ON restarts the motor suddenly.
The inverter must be used for three-phase induction motors.
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 product.
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.
The effect of electromagnetic interference must be reduced
by using a noise filter or by other means. Otherwise nearby
electronic equipmen t may be affected.
Appropriate measures must be taken to suppress
harmonics. Otherwise power supply harmonics from the
inverter may heat/damage the power factor correction
capacitor and generator.
When driving a 400V 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.
When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting
operations because all parameters return to the initial value.
The inverter can be easily set for high-speed operation.
Before changing its setting, the performances of the motor
and machine must be fully exam ined.
Stop status cannot be hold by the inverter's brake function.
In addition to the inverter’s brake function, a holding
device must be installed to ensure safety.
Before running an inverter which had been stored for a long
period, inspection and test operation must be performed.
Static electricity in your body must be discharged before
you touch the product. Otherwise the product may be
damaged.
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.
(5) Emergency stop
A-2
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 input side trips, the wiring
must be checked for fault (short circuit), and internal parts
of the inverter for a damage, etc. The cause of the trip must
be identified and removed before turning ON the power of
the breaker.
When any protective function is activated, appropriate
corrective action mus t be taken, and the inverte r must be
reset before resuming operation.
(6) Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on
the control circuit of the inverter. It will cause a failure.
(7) Disposal
The inverter must be treated as industrial w aste.

(Refer to page 48)
(Refer to page 7)
(Refer to page 7)
( Refer to Chapter 4
of the FR-E700 Instruction
Manual (Applied))
Brake resistor
(FR-ABR, MRS type, MYS type)
Braking capability can be i mproved. (0.4K
or higher)
Always install a thermal relay when using
a brake resistor whose capacity is 11K or
higher.
(Refer to page 19)
AC power supply
Use within the permissible power supply
specifications of the inverter. To ensure
safety, use a molded case circuit breaker,
AC reactor (FR-HAL)
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
Molded 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.
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.
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must 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
(500kVA 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/+ and P1 to
connect the DC reactor.

Noise filter (ferrite core) *
(FR-BSF01, FR-BLF)
* Filterpack (FR-BFP2), which contains DC reactor and EMC filter in one package, is also available.
Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.
High power factor
converter (FR-HC2)
Power supply harmonics
can be greatly suppressed.
: Install this as required.
NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as
possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer
to page 8)
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit
to protect them from no ise. (Refer to page 9)
Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.
This will cause the invert er to trip or the capacitor and surge suppressor to be damaged. If a ny of the above devices are
connected, immediatel y remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequen cy components, which may interfere with t he
communication devices (such as AM radios) used near the inverter. In this case, install options among the capacitor type
EMC filter FR-BIF (for use in the in put side only), the ferrite core type E MC filter FR-BSF01/FR-BLF, Filterpack, and EMC
filter to minimize the interferenc e. ( Refer to Chapter 3 of the FR-E700 Instruction Manual (Applied)).

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor. Take the following measures 1) or 2) in this case.
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.

NOTE
Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray
capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention
function occurs, increase the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention
operation selection in Chapter 4 of the FR-E700 Instruction Manual (Applied))
When using the automatic restart after instantaneous power failure function with the wiring length exceeding 100m,
select without frequency search (Pr. 162 = "1, 11"). (

Wiring method
1) Strip off the sheath of the wire of the control circuit to wire.
Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur
among neighboring wires. If the length is too short, wires might come off.
Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it. Use a blade
terminal as necessary.

Wiring
Micro signal contacts Twin contacts
(1) Control circuit common terminals (SD, 5, SE)
Terminals SD, SE and 5 are common terminals for I/O signals. (All common terminals are isolated from each other.) Do not
earth them. Avoid connecting the terminals SD and 5 and the terminals SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL, MRS, RES) and the pulse train
output terminal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler.
Terminal 5 is a common terminal for the frequency setting signals (terminal 2 or 4). It should be protected from external
noise using a shielded or twisted wire.
Terminal SE is a common terminal for the open collector output terminal (RUN, FU). The contact input circuit is isolated
from the internal control circuit by photocoupler.
(2) Wiring instructions
It is recommended to use the wires of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.
The maximum wiring length should be 30m (200m for terminal FM).
Do not short terminals PC and SD. Inverter may be damaged.
When using contact inputs, use two or more parallel micro-signal contacts or
twin contacts to prevent contact faults since the control circuit input signals are
micro-currents.
To suppress EMI, use shielded or twisted cables for the control circuit terminals and run them away from the main and
power circuits (including the 200V relay sequence circuit). For the cables connected to the control circuit terminals, connect
their shields to the common terminal of the connected control circuit terminal. When connecting an external power supply to
terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do
not directly earth (ground) the shield to the enclosure, etc.
Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.
When using an external power supply for transistor output, note the following points to prevent a malfunction caused by
undesirable current.
Do not connect any terminal SD on the inverter and the 0V terminal of the external power supply (when the sink logic is
selected).
Do not connect terminal PC on the inverter and the +24V terminal of the external power supply (when the source logic is
selected).
Do not install an external power source in parallel with the internal 24VDC power source (connected to terminals PC and
SD) to use them together.
Refer to Chapter 2 of the FR-E700 Instruction Manual (Applied) for the detail.
