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 (-10~40oC).
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 inside 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 Wiring of Main Power Supply Circuit
4.3.1 Description on Main Power Supply Terminals
4.3.2 Cautions when wiring the Main Power Supply
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.

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.
Do not connect static condenser or noise filter at the output of the drive. It may cause frequent trip on the
drive, or static condenser or noise filter may be destroyed due to overheating.
Use specified thickness of wires for input/output wiring for the drive. If wires are thinner than specified
thickness, it may cause torque reduced due to voltage decrease or induce fire accident from overheating.
Maintain wiring distance between drive and motor within 50m. If it is longer than 50m, be sure to use the
motor with reinforced insulation or micro-surge filter.
4.3.3 Cautions on Ground Wiring
4.3.4 Specifications of Recommended Wires and Terminal Screw
Since a leak current is generated from high speed switching of the drive, it is required to ground the drive
to prevent electric shock.
Grounding class 3 to be applied to 200V class drive, ground resistance to be under 100Ω.
Grounding class special 3 to be applied to 400V class drive, ground resistance to be under 10Ω.
Use thicker wires than specified one for ground wire.
Ground system supply is TN.
Apply specified torque for fastening the terminal screw.
Weak fastening may cause malfunction and too strong fastening may destroy terminal block.
Use 600V class wires.
