OPERATING PRECAUTIONS
1) Transport and Installation
zBe sure to carry inverter in a proper way suitable for its weight, or it may result
in damage to inverter.
zDo not pile up inverters above allowable limit.
zBe sure to install the inverter as directed in this instruction manual.
zDo not turn off the power supply to the damaged inverter.
zDo not open the front cover while carrying the inverter.
zDo not place the heavy material on the inverter.
zThe direction of installation should be observed properly as criterions specified
in this manual show.
zMake sure that you should not put screw, metal material, water, oil and the in-
flammable something else.
zKeep in mind that inverter is very vulnerable to drop from the mid air and strong
shock.
zBe certain to use the inverter under the following conditions.
Ambient temperature - 10 ~ 40 ℃ (Non-frozen)
Humidity Below 90% RH (Dewdrop should not be
formed)
Storage temperature - 20 ~ 65 ℃
Ambient condition Free of corrosive gas, inflammable gas, oil-
waste and dust
Environment
Altitude/vibration Below 1000m above sea level, Below
5.9m/sec²(=0.6g)
2) Wiring works
zDo not connect phase-leading capacitors, surge filter, radio noise filter to the
output of inverter.
zOutput terminals (terminals named U, V, W respectively) should be connected
in a proper phase sequence.
3) Adjustment before starting trial operation
zBe sure to check relevant parameters for the application before starting trial
operation.
4) Directions
zBe sure not to approach the machine when retry function is selected. The ma-
chine may start working suddenly.
zStop key on the keypad should be set to be in use. For safety, additional emer-
gency stop circuit should be required.
zInverter restarts if alarm condition is cleared while FX/RX signal is on. There-
fore, be sure to operate the alarm reset switch after checking if FX/RX signal is
off.
zNever modify the inverter for inappropriate use.
zMotor may not be protected by electronic thermal protection.

iv
Safety instructions
zDo not start or stop the inverter by the magnetic contactor installed at the in-
put of inverter.
zNoise filter should be used for the minimization of troubles by electro-
magnetic noise. Electronic equipments close to the inverter should be pro-
tected against the damage caused by troubles.
zBe sure to install the AC reactor at the input of inverter in case of input voltage
unbalance. Otherwise, generator or phase-leading capacitors may be destroyed
by the harmonic current from inverter.
zIf 400V class motor is used with the inverter, insulation-enforced motor should
be used or countermeasures against the suppression of micro-surge voltage
generated by the inverter should be carried out. Otherwise, micro-surge volt-
age is generated across input terminal for the motor and this voltage lowers al-
lowable insulation break-down voltage and then, may cause the destruction of
the motor.
zBe sure to set the parameters once more, in case of initialization of parameters,
all values of parameters is set to values of factory setting.
zHigh speed operation can be set easily, therefore be sure to check the perform-
ance of motor or machine before changing parameter value.
zDC braking function cannot produce a zero-servo torque. If required, additional
equipment should be installed.
zWhen inverter trip or emergency stop (BX) occurs without keypad connected,
LED on the control board will blink by the interval of 0.5 sec. But LED will blink
by 1 sec when keypad is connected.
5) Countermeasure against malfunction troubles
zIf inverter is damaged and then gets into uncontrollable situation, the machine
may lead to the dangerous situation, therefore to avoid this situation, be sure
to install the additional equipments such as brake.
6) Maintenance, inspection and parts replacement
zDo not perform the megger (insulation resistance check) test on the control
board.
zPlease refer to Chapter 7 (intervals for parts replacement).
7) Disposal
z Handle the inverter as an industrial waste when disposing of it.
8) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter without
a circuit breaker, a cover or partially open. Never run the inverter like this. Always place
the cover with circuit breakers and follow this instruction manual when operating the
inverter.

3.1.7 Special care should be taken in case the inverter is to be installed in the panel.
In case more than 2 inverters are to be installed or ventilation fan is to be installed in the panel, make
sure that inverter and ventilation fan is properly installed. If they are poorly installed, it causes the
increase of an ambient temperature and less effective ventilation. Therefore, be sure to keep the ambient
temperature of inverter below the allowable temperature.
3.1.8 Install the inverter tightly not to get loose using proper sized bolt or screw.

3.3.2 Cautions to be required for wiring to Power Circuit Terminal
①Connect terminals ( R, S and T) to 3 phase input power supply after checking inverter nameplate
attached on the inverter. Never connect terminals (U, V and W) to 3 phase input power supply. It results in
lethal damage to the inverter.
②Never connect the phase advancing capacitor to the inverter output. If already installed, remove the
phase advancing capacitor clearly.

3. Installation and wiring
③Cable between inverter output and motor should be less than 30m long. If cable gets long, surge voltage
appears across motor terminals depending on the cable parameters. Especially, in 400V class motor case,
insulation withstanding voltage may be decreased. Use an insulation-enforced motor when 400V class motor
is used.
④Crimp terminal with insulation cap should be used for the input power supply and the motor.
⑤After finishing wiring, be certain to remove all the wire or cable scraps inside the inverter.
⑥Use the shield cable or twist-paired wire for control circuit terminal. Do not put them into the same wiring
duct for the power terminal.
⑦When wiring is changed after operating the inverter, be sure to check LCD window on the keypad or
charge lamp is turned off. Capacitors inside inverter are charged with high voltage and it may result in lethal
injury.
⑧Below 22kW inverter, B1 and B2 on the power terminal should not be connected to anything else other
than DB resistors.
3.3.3 Main Power Circuit Wire Sizes and Grounding Wire Size
①Main Power Circuit Wire Sizes
If wiring for the main power terminal is not performed properly, it may cause severe damage to inverter or
lethal injury to inverter operator. Be sure to use 600V, 75℃copper wire.
