OPERATING PRECAUTIONS
1) Transport and Installation
l Be sure to carry inverter in a proper way suitable for its weight, or it may result
in damage to inverter.
l Do not pile up inverters above allowable limit.
l Be sure to install the inverter as directed in this instruction manual.
l Do not turn off the power supply to the damaged inverter.
l Do not open the front cover while carrying the inverter.
l Do not place the heavy material on the inverter.
l The direction of installation should be observed properly as criterions specified
in this manual show.
l Make sure that you should not put screw, metal material, water, oil and the
inflammable something else.
l Keep in mind that inverter is very vulnerable to drop from the mid air and strong
shock.
l Be 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,
oilwaste and dust
Environment
Altitude/vibration Below 1000m above sea level, Below
5.9m/sec²(=0.6g)
2) Wiring works
l Do not connect phase-leading capacitors, surge filter, radio noise filter to the
output of inverter.
l Output terminals (terminals named U, V, W respectively) should be connected
in a proper phase sequence.
3) Adjustment before starting trial operation
l Be sure to check relevant parameters for the application before starting trial
operation.
4) Directions
l Be sure not to approach the machine when retry function is selected. The
machine may start working suddenly.
l Stop key on the keypad should be set to be in use. For safety, additional
emergency stop circuit should be required.
l Inverter restarts if alarm condition is cleared while FX/RX signal is on.
Therefore, be sure to operate the alarm reset switch after checking if FX/RX
signal is off.
l Never modify the inverter for inappropriate use.
l Motor may not be protected by electronic thermal protection.

iv
Safety instructions
l Do not start or stop the inverter by the magnetic contactor installed at the
input of inverter.
l Noise filter should be used for the minimization of troubles by electro-
magnetic noise. Electronic equipments close to the inverter should be
protected against the damage caused by troubles.
l Be 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.
l If 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
voltage is generated across input terminal for the motor and this voltage
lowers allowable insulation break-down voltage and then, may cause the
destruction of the motor.
l Be sure to set the parameters once more, in case of initialization of parameters,
all values of parameters is set to values of factory setting.
l High speed operation can be set easily, therefore be sure to check the
performance of motor or machine before changing parameter value.
l DC braking function cannot produce a zero-servo torque. If required, additional
equipment should be installed.
l When 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
l If 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
l Do not perform the megger (insulation resistance check) test on the control
board.
l Please refer to Chapter 7 (intervals for parts replacement).
7) Disposal
l 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.

2.1.7 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.
2.1.8 Install the inverter tightly not to get loose using proper sized bolt or screw.

. Installation and wiring
③ Cable between inverter output and motor should be less than 300m 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.
④ Crimp terminal with insulation cap should be used for the input power supply and the motor.
⑤ After finishing wiring, be certain to remove all the wire or cable scraps inside the inverter.
⑥ Use the shield cable or twist-paired wire for control circuit terminal. Do not put them into the same wiring
duct for the power terminal.
⑦ When 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.
⑧ Below 22kW inverter, B1 and B2 on the power terminal should not be connected to anything else other
than DB resistors.

1) Apply the rated torque to terminal screws. Loose screws can cause of short circuit or malfunction.
Tightening the screws too much can damage the terminals and cause a short circuit or malfunction.
② Grounding Wire Size and Caution to be taken
l Be sure to ground the motor and the inverter to prevent electric shock injury. (200V class:
ground impedance 100Ω, 400V class: ground impedance 10Ω)
l Connect the inverter ground to the ground terminal exclusively used for the inverter.
l It is strongly recommended that as thick a grounding wire as possible be used and wire be short.

2.4.3 Wiring the Control Circuit Terminal
① Shield wire or vinyl insulated wire are highly recommended to be used for the control circuit terminal.
② Be sure to use twisted shield wire if wiring distance gets too long.
③ Wire should be at least as thick as 0.2 ~ 0.8 mm2 (18 ~ 26 AWG).
④ Screwing torque limit should be kept under 5.2 lb-in.
⑤ Maximum interrupting capacity of auxiliary contact 1, 2 is of AC 250V/1A, DC 30V/1A.
⑥ Maximum interrupting capacity of fault alarm relay A, B contact is of AC 250V/1A, DC 30V/1A.
⑦ Open collector output 1, 2 and 3 can be used below maximum of 24V/100mA.
⑧ Wires for the control circuit terminal should be separated from ones for the power circuit terminal, if possible
and in case wires for both control circuit terminal and the power circuit one cross each other, they should be
crossed at right angles (90°).
2.4.4 Caution on wiring pulse encoder
1) Check-up of the coupling and alignment of motor and encoder shaft
① Be sure to mount the pulse encoder at the location where it rotates at the same speed as the motor does.
② In case there is speed slip between the motor shaft and encoder shaft, the motor may not start or it causes
mechanical vibration.
③ Poor alignment of motor and encoder shaft results in torque ripple and causes mechanical vibration which has
the same frequency as the motor speed at the constant speed region.
2) Wiring the pulse encoder
① Be sure to use twist paired shield wire and ground shield wire to screw for earth on the I/O PCB.
② Signal wires should be separated from the power lines, if possible. Electromagnetic noise may affect the pulse
encoder output signals.
