Make sure that you should not put screw, metal material, water, oil and the inflammable something else.
Keep in mind that the VFD is very vulnerable to drop from the mid air and strong shock.
Don't let the inverter exposed to rain, snow, fog, dust, etc.
Do not cover, nor block, the ventilating system having cooling fan. It may cause the VFD overheated.
Be sure to check the power is off when installing the VFD.
To prevent the risk of fire or electric shock, keep the connected wire in a sound condition.
Use the wire that meets the standard in a recommended length.
B. Wiring
A professional installer should have done the wiring and checking.
Do wiring after installing the VFD body.
Do not connect phase-leading capacitors, surge filter, radio noise filter to the output of the VFD.
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 the VFD in its
operation.
Use the twisted pair shield wire for the ground terminal of the VFD

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 disappeared when the load
is connected and it is not the indication of abnormal condition.
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 operation.
C. Adjustment before starting trial operation
Safety Instructions
If the VFD 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.
E. Reaction on Failure and Malfunction
Do not perform the megger (insulation resistance check) test on the control board.
F. Maintenance, inspection and parts replacement
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.
Never modify the VFD 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 VFD.
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 unbalance.
Otherwise, generator or phase-leading capacitors may be destroyed by the harmonic current from inverter.
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.
DC braking function cannot produce a zero-servo torque.
If required, additional equipment should be installed.
Do not change wiring, nor disconnect connector or option card during the operation of the VFD.
Do not disconnect the motor wiring while the voltage of inverter is output.
Mishandling may cause damage to the VFD.

4. Installation
4.1 Cautions on Installation
Be careful so that the plastic parts of the inverter may not be damaged.
Do not move the product holding the cover only.
Do not install the product where there is vibration, a press or truck.
Life of the inverter greatly influenced by the surround ing temperatures, make sure that the surrounding
temperature does not exceed th e permitted temperature (-10~0℃).
The life of the inverter is affected by ambient temperature. Place that inverter installed in of ambient
temperatures should not exceed the following allowable temperature.
When the inverter is installed inside the panel, panel temperature must not exceed the following allowable
temperature. In other word, the ambient temperature insi de or outside of the panel, regardless of the
installation, needs to be measured a round 5cm of the inverter.
Install the inverter on an inflammable surface because its temperature rises high during operation.
Sufficient space is required to prevent heat saturation because the inverter emits heat.
Chapter 4 Installation
Caution
Avoid direct rays of light or a warm and humid place.
Install the inverter in a closed panel or clean place free from foreign substances such as oil mist and
fiber dust.

4.3.1 Description on Main Power Supply Terminals
4.3.2 Cautions when wiring the Main Power Supply
U V W FG FG L2 L1
Execute wiring work after checking if DC power of drive is discharged (under 30V).
Be sure to install wiring breaker (MCCB) between AC input power and drive input power terminals (R,S,T).
Use the wiring breaker (MCCB) with 1.5~2 times larger capacity than rated current of the drive.
Sometimes EMI occurs due to high speed switching of the drive and it makes radio
interference on electronic devices used around the drive. For that case, install EMC filters
between AC power input and the drive to reduce interference.
If AC input power is connected to output terminals (U,V,W) of drive, drive will be
damaged. Be sure to connect it to input terminals.
Even though power input terminals (R,S,T) may be connected regardless to phase
sequence of AC input power, it is required to consider rotation direction of the motor when
connecting input terminals of the motor to output terminals of the drive (U,V,W). If rotation
direction of the motor is reversed, 2 lines from drive output terminals (U,V,W) should be
exchanged each other.
Do not make short circuit nor ground with drive output terminals (U,V,W). Short circuit or
ground of output terminals may damage on the drive.
