zDo 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.
zIf 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.
zBefore starting wiring or inspection, switch power off, wait for more than 10
minutes, and check for residual voltage with a meter (refer to chapter 2 for
further details) etc.
zEarth the inverter.
zAny person who is involved in the wiring or inspection of this equipment should
be fully competent to do the work.
zAlways install the inverter before wiring. Otherwise, you may get an electric
shock or be injured.
zOperate the switches and potentiometers with dry hands to prevent an electric
shock.
zDo not subject the cables to scratches, excessive stress, heavy loads or
pinching. Otherwise, you may get an electric shock.
zDo not change the cooling fan while power is on.
It is dangerous to change the cooling fan while power is on.
2. Fire Prevention
CAUTION
zMount the inverter and brake resistor on an incombustible surface. Installing the
inverter directly on or near a combustible surface could lead to a fire.
zIf the inverter has become faulty, switch off the inverter power. A continuous
flow of large current could cause a fire.
zWhen a brake resistor is used, use an alarm signal to switch power off.
Otherwise, the brake resistor will overheat abnormally due a brake transistor or
other fault, resulting in a fire.
zDo not connect a resistor directly to the DC terminals P(+), N(−). This could
cause a fire.

(2)Wiring
CAUTION
zDo not fit capacitive equipment such as a power factor correction capacitor,
radio noise filter or surge suppressor to the output of the inverter.
zThe connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.
(3)Trial run
CAUTION
zCheck all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4)Operation
WARNING
zWhen you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
zThe [STOP] key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
zMake sure that the start signal is off before resetting the inverter alarm. A failure
to do so may restart the motor suddenly.
zThe load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
zDo not modify the equipment.
CAUTION
zThe electronic overcurrent protection does not guarantee protection of the
motor from overheating.
zDo not use a magnetic contactor on the inverter input for frequent
starting/stopping of the inverter.
zUse a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
zTake measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.

A - 5
CAUTION
zWhen a 400V class motor is inverter-driven, it should be insulation-enhanced or
surge voltages suppressed. Surge voltages attributale to the wiring constants
may occur at the motor terminals, deteriorating the insulation of the motor.
zWhen parameter clear or all clear is performed, each parameter returns to the
factory setting. Re-set the required parameters before starting operation.
zThe inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
zIn addition to the inverter's holding function, install a holding device to ensure
safety.
zBefore running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5)Emergency stop CAUTION
zProvide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
(6)Maintenance, inspection and parts replacement
CAUTION
zDo not carry out a megger (insulation resistance) test on the control circuit of
the inverter.
(7)Disposing of the inverter CAUTION
zTreat as industrial waste.

1.2 Basic Configuration
1.2 Basic Configuration
1.2.1 Basic configuration
The following devices are required to operate the inverter. Proper peripheral devices
must be selected and correct connections made to ensure proper operation. Incorrect
system configuration and connections can cause the inverter to operate improperly, its
life to be reduced considerably, and in the worst case, the inverter to be damaged.
Please handle the inverter properly in accordance with the information in each section
as well as the precautions and instructions of this manual. (For connections of the
peripheral devices, refer to the corresponding manuals.)
Name Description
Power
supply Use the power supply within the
permissible power supply specifications
of the inverter. (Refer to page 188.)
Earth leakage
circuit breaker
or no-fuse
breaker
The breaker should be selected with
care since a large inrush current flows
in the inverter at power on. (Refer to
page 42.)
Magnetic
contactor Do not use this magnetic contactor to
start or stop the inverter. It might reduce
the inverter life. (Refer to page 42.)
Reactors
The reactors must be used when the
power factor is to be improved or the
inverter is installed near a large power
supply system (1000KVA or more and
wiring distance within 10m (32.81 feet)).
Make selection carefully.
Inverter
•The inverter life is influenced by
ambient temperature. The ambient
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 12.)
•Wrong wiring might lead to inverter
damage. The control signal lines should
be kept away from the main circuit to
protect them from noise. (Refer to page
14.)
Devices
connected
to the output
Do not connect a power capacitor,
surge suppressor or radio noise
filter to the output side.
Ground To prevent an electric shock, always
ground the motor and inverter.
Japanese Harmonic Suppression Guideline
The "harmonic suppression guideline for household appliances and general-purpose
products" was issued by the Ministry of International Trade and Industry in September,
1994. This guideline applies to the 3.7K* and less models of three-phase 200V classes.
By installing the power factor improving reactor (FR-BEL or FR-BAL), inverters comply
with the "harmonic suppression techniques for transistorized inverters (input current 20A
or less)" established by the Japan Electrical Manufacturers' Association.
* For the single-phase 100V class, the guideline applies to 0.75kW and less models.
