Wiring
Caution
A professional installer should have done the wiring and checking.
Do wiring after installing the inverter body.
Do not connect phase-leading capacitors, surge filter, radio noise filter to the output
of inverter.
Output terminals (terminals named U, V, W respectively) should be connected in a
proper phase sequence.
Make sure that there is not any short circuit terminal, wrong wiring. It may cause
spurious operation or failure.
Refrain from using a cable other than the cable shielded when you connect control
circuit wiring.
Adopt the shielded wire only when wiring the control circuit. It may cause the failure
of inverter in its operation. Use the twisted pair shield wire for the ground terminal of
the inverter.
Warning
To prevent an electric shock, be sure to check if MCCB and MC are
switched OFF before wiring
Otherwise, it may cause an electric shock.
Adjustment before starting trial operation
Do not supply the excessive range of voltage displayed in the user manual to the
each terminal. It may cause damage to the inverter.
Current hunting can be occurred in the low speed territory during testing. It occurs
where the capacity is above 110kW with no-load and the axis is not connected.
The current hunting has a gap according to the motor characteristic. It will be dis-
appeared when the load is connected and it is not the indication of abnormal condi-
tion.
If the hunting is occurred seriously, please stop the testing and operates with the
load.
Be sure to check relevant parameters for the application before starting trial opera-
tion.
How to Use
Be sure not to approach the machine when retry function is selected. The machine
may start working suddenly.
Stop key on the keypad should be set to be in use. For safety, additional emergency
stop circuit should be required.
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.
Never modify the inverter for inappropriate use.
When a magnetic contactor is installed on the power source, do not frequently start
or stop using this magnetic contactor. It may cause the failure of inverter.

Safety Instructions
v
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.
Be sure to install the AC reactor at the input of inverter in case of input voltage un-
balance. Otherwise, generator or phase-leading capacitors may be destroyed by
the harmonic current from inverter.
If 400V class motor is used with the inverter, insulation-enforced motor should be
used or countermeasures against the suppression of micro-surge voltage generat-
ed 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.
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.
High speed operation can be set easily, therefore be sure to check the performance
of motor or machine before changing parameter value.
DC braking function cannot produce a zero-servo torque. If required, additional
equipment should be installed.
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. This function displays which trip will be occurred ac-
cording to the connection of keypad.
Do not change wiring, nor disconnect connector or option card during the operation
of inverter.
Do not disconnect the motor wiring while the voltage of inverter is output. Mishan-
dling may cause damage to the inverter.
Be sure to handle the inverter and option care in the order recommended in the
Electro Static Discharge (ESD) Countermeasure. Mishandling may lead to damage
to the circuit on the PCB caused by ESD.
Countermeasure against malfunction troubles
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.
Maintenance, inspection and parts replacement
Do not perform the megger (insulation resistance check) test on the control board.
Please refer to intervals for parts replacement on Chapter 8.
Disposal
Handle the inverter as an industrial waste when disposing of it.
Our inverter contains the raw material of value that can be recycled from the aspect
of energy and resource preservation. All the package materials and metal parts are
recyclable. Plastics are also recyclable, but may be burnt under the controllable en-
vironment depending on the local regulation.

Safety Instructions
vi
General Instruction
The drawing in this user manual is represented the details of the inner inverter, so,
the drawing is described without cover part and circuit breaker. But, cover and cir-
cuit breaker should be mounted before the operation following to the instruction of
user manual.
Turn off the power of inverter when the inverter is not used.
Cleaning
Be sure to operate the inverter under a clean condition.
When cleaning the inverter, be sure to check the inverter is off. Start cleaning it with
all the plugs connected with the inverter socket removed.
Never clean the inverter using wet cloth or water. Wipe the stained area softly using
the cloth completely wet with a neutral detergent or ethanol.
Never use the solution such as acetone, benzene, toluene, alcohol, etc. They may
cause the coating on the surface of the inverter to peel off. In addition, do not clean
LCD display, etc. using detergent or alcohol.
Storage
Be sure to keep the inverter under the following conditions if you don't use it for a
long period of time.
Make sure that you satisfy the recommended storage environment. (See page v.)
If the storage period exceeds 3 months, be sure to keep it at the ambient tempera-
ture of -10 ~ +30˚C to prevent『Deterioration by Temperature』of electrolytic con-
denser.
Be sure to keep it in a proper package to prevent moisture, etc. Put the desiccant
(Silica Gel), etc., in the package so that the relative humidity in the package can be
maintained at 70% or less.
When it is exposed to moisture or dust (mounted on the『System』or 『Control
Panel』, etc. installed at the construction site), remove it and then keep it under the
environmental condition specified in the page v.
Caution
If the inverter has been left long with electric current not charged, the na-
ture of electrolytic condenser can be deteriorated. So be sure to have it
plugged in for 30 ~ 60 minutes once a year. Do not perform wiring and op-
eration of the output side (secondary side).

Be sure to check mechanical and electrical installation environment before you
start the inverter. Read through the checking list below. Be sure to read through
the Caution for Safety on this User's Manual prior to the operation of inverter.
Checking List
Mechanical Installation Checking List
Be sure to check the surrounding environment is allowed for operation. (Read
through the ‘Caution on Installation’)
Inverter is a heat-generating device. Be sure to sufficiently secure the
surrounding space to prevent thermal saturation phenomenon.
Be sure to check air is circulated in a normal condition.
Be sure to check motor and drive system are ready to start.
Electrical Installation Checking List
Make sure that the protective grounding is properly done.
Replace the condenser with new one if it lasted longer than two years.
Set the input voltage to the nominal input voltage of the inverter.
Check if the input voltage connected with R, S, T and then fasten them tightly
using an accurate torque wrench.
Check if input power fuse and circuit breaker are properly installed.
Install the motor cable away from the other cable.
Check if the ext. input/output is properly connected.
Check if the input voltage is properly connected with the output terminal of
inverter.
This chapter describes general items for the installation and wiring of an
inverter and includes instruction for wiring to power terminal and control
one and caution in case of wiring, and also explains the function of each
terminal for both power and control.

3.1 Caution on Installation
3.1.1 Do not install the inverter in a location where excessive vibration
is present.
Be cautious when installing on presses or moving equipment.
3.1.2 Caution on ambient temperature
Ambient temperature greatly affects inverter lifetime, therefore be sure to
keep the ambient temperature of installation location at –10 to 40℃.
3.1.3 Install the inverter on the uninflammable material. The inverter
operates at high-temperature.
3.1.4 Avoid a humid and hot location.
3.1.5 Install the inverter in a location free of oil mist and dust.
Totally enclosed panel can be used to protect the inverter against that
materials. Cooling air must be clean, free from corrosive materials and
electrically conductive dust.

3.1.6 Secure the installation space enough to protect the inverter
against the overheating.
At least the room that 30 cm from upper and lower of inverter and 20 cm
from left and right of inverter is required for installing more than 30 kW
products.
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.
