Safety information
• Do not open the cover of the equipment while it is on or operating. Likewise, do not operate
the inverter while the cover is open. xposure of high voltage terminals or charging area to
the external environment may result in an electric shock. Do not remove any covers or
touch the internal circuit boards (PCBs) or electrical contacts on the product when the
power is on or during operation. Doing so may result in serious injury, death, or serious
property damage.
• Do not open the cover of the equipment even when the power supply to the inverter has
been turned off unless it is necessary for maintenance or regular inspection. Opening the
cover may result in an electric shock even when the power supply is off.
• The equipment may hold charge long after the power supply has been turned off. Use a
multi-meter to make sure that there is no voltage before working on the inverter, motor or
motor cable.
•
Supply earthing system: TT, TN, not suitable for corner-earthed systems

2
• This equipment must be grounded for safe and proper operation.
• Do not supply power to a faulty inverter. If you find that the inverter is faulty, disconnect the
power supply and have the inverter professionally repaired.
• The inverter becomes hot during operation. Avoid touching the inverter until it has cooled to
avoid burns.
• Do not allow foreign objects, such as screws, metal chips, debris, water, or oil to get inside
the inverter. Allowing foreign objects inside the inverter may cause the inverter to
malfunction or result in a fire.
•
Do not operate the inverter with wet hands. Doing so may result in electric shock.
• Do not modify the interior workings of the inverter. Doing so will void the warranty.
• The inverter is designed for 3-phase motor operation. Do not use the inverter to operate a
single phase motor.
• Do not place heavy objects on top of electric cables. Doing so may damage the cable and
result in an electric shock.

2 Installation Instruction
2.1 Installation Considerations
Inverters are composed of various precision, electronic devices, and therefore the
installation environment can significantly impact the lifespan and reliability of the
product. The table below details the ideal operation and installation conditions for
the inverter.
Items
Description
Ambient Temperature*
- CT (Heavy Duty) load : - 10 ~ 50 ℃ (without ice or frost)
- VT (Normal Duty) load : - 10~ 40 ℃ (without ice or frost)
(It is recommended that you use less than 80% load when you use
VT load at 50 ℃ .)
- IP54 product: -10~40 ℃ (without ice or frost)
Ambient Humidity 90% relative humidity (no condensation)
Storage Temperature - 4–149
°
F (-20–65 ℃ )
nvironmental Factors An environment free from corrosive or flammable gases, oil residue
or dust
Altitude/Vibration Lower than 3,280 ft (1,000 m) above sea level/less than 0.6 G (5.9
m/sec2)
Air Pressure 70 –106 kPa
* The ambient temperature is the temperature measured at a point 2” (5 cm) from the
surface of the inverter.

12
2.2 Selecting and Preparing a Site for 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 cart..
Life of the inverter greatly influenced by the surrounding temperatures, make sure that the
surrounding temperature does not exceed the permitted temperature (-10 ~ 50 C). 
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 a 5cm gap around the inverter as shown.
<Measurement Points of Surrounding Temperature>
Allowable Temperature
Characteristics, such as no ice in
ambient Temperature
CT(Heavy Duty) load: - 10 ~ 50 ℃
VT(Normal Duty)load: - 10~ 40 ℃
(However, VT(Normal Duty) in 50 ℃ ,
less than 80% of the load use
recommended)
IP54 Product : -10 ~40 ℃

13
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.

14
Remark
Over 50cm, B : over 20cm is necessary when you install an inverter above 30kW
If you install two or more inverters inside the panel, be careful about the location of the
ventilation fan and inverter. See the figure below.
Install the inverter upright using screws or bolts so that the inverter does not move.
Note
Arrange the panels in order to the hot air generated by the heating of the inverter should be
released.
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.
In order to meet the MC standard, 200V 30~75kW and more than 90kW product
should be installed inside a metal cabinet or panel.

2.3 Mounting
Mount the inverter on a wall or inside a panel following the procedures provided below.
Before installation, ensure that there is sufficient space to meet the clearance specifications,
and that there are no obstacles impeding the cooling fan’s air flow.
1 Use a level to draw a horizontal line on the mounting surface, and then carefully mark
the fixing points.
2 Drill the two upper mounting bolt holes, and then install the mounting bolts. Do not fully
tighten the bolts at this time. Fully tighten the mounting bolts after the inverter has been
mounted.
3 Mount the inverter on the wall or inside a panel using the two upper bolts, and then fully
tighten the upper mounting bolts.

16
4 Install the two lower mounting bolts. nsure that the inverter is placed flat on the
mounting surface, and that the installation surface can securely support the weight of
the inverter.
Note
The quantity and dimensions of the mounting brackets vary based on frame size.

17
• Do not transport the inverter by lifting with the inverter’s covers or plastic surfaces. The
inverter may tip over if covers break, causing injuries or damage to the product. Always
support the inverter using the metal frames when moving it.
• Hi-capacity inverters are very heavy and bulky. Use an appropriate transport method that is
suitable for the weight.
•
Do not install the inverter on the floor or mount it sideways against a wall. The inverter must
be installed vertically, on a wall or inside a panel, with its rear flat on the mounting surface.

2.4 Motor Connection
Connect motor by following procedure. Check cable specifications on 5.2 before connecting .
1 First, separate the keypad and the cable of keypad(❶)
x) 0.75~7.5kW
2 Loosen the bolt that secures the top cover. Then remove the cover by lifting it. (❷)
3 Connect the cables to the power terminals.

<Standard type>
<Conduit type>
• Apply rated torques to the terminal screws. Loose screws may cause short circuits and
malfunctions. Tightening the screw too much may damage the terminals and cause short
circuits and malfuctions.
• Use copper wires only with 600 V, 75 ℃ rating for the power terminal wiring, and 300 V,

20
75 ℃ rating for the control terminal wiring.
• Power supply wirings must be connected to the R, S, and T terminals. Connecting them to
the U, V, W terminals causes internal damages to the inverter. Motor should be connected
to the U, V, and W Terminals. Arrangement of the phase sequence is not necessary.
