1-1 Important Notes
Danger
Caution: risk of electric shock
It is absolutely prohibited to remove the cover
The risk of casualties exists because there are high-voltage circuits inside, accidental touch of which
would cause electric shock.
Caution: Fire Hazard！
Immediately stop the device when peculiar smell, abnormal noise, smoke or sparks, etc. are found in
the device (turn the power switch to "off" position), and then set the input side circuit breaker which is
set outside to OFF. And contact the sale store or business office of the Company where the device is
purchased.
In case of a fire, please use extinguisher for electrical fire (dry powder), but do not use water for fire
fighting.
1-2 Notes on Use
Caution
Before starting the inverter, confirm the safety status of the load first, and then start running
operation following the instruction manual.
Arbitrary power-on has the risk of accidents such as electric shock etc.
Do not smoke or use fireworks around the inverter.
As the explosions and damage may result in personal injury and fire.
Do not keep containers which contain water such as vase etc. above the equipment.
In case the vase is overturned, the water flowing out will penetrate inside the device and cause fire.
Do not sit or stand on top of the equipment, and do not lean on it or treat it as a footboard.
Otherwise, personal injury may be caused by overturn of the equipment.
Do not insert sticks, fingers etc. into the fan.
Because the rotating fan would cause personal injury.
During operation, do not short-circuit the input terminal and output terminal.
As the current return will result in electric arc, the arc light can cause personal burns and visual
impairment.
Its use in the following applications is absolutely prohibited.
a) Medical equipment which are directly related to life.
b) Trolley buses which may lead to personal injury.
c) Important computer systems for the community, public utilities.
d) Equipment with these as standards.
When used in the above-mentioned load equipment, please consult the Company in advance. For
equipment which have significant impact on personal safety and the maintenance of public functions,
special measures are required on the use, maintenance and management, such as multiple of the
system, setting up generating equipment for emergency use etc..

2-3 Precautions on Use
2-3 Precautions on Use
1. Use the product in a location satisfying the standard environmental specifications (temperature,
humidity, vibration, dust, water drop, and toxic gases etc.).
2. Before starting up the product for the first time, carefully check the wiring. Make sure that the power
cable (input) and motor cable (output) are connected correctly. Otherwise, the inverter will be damaged.
3. Since the ambient temperature of the installation location greatly affects the life of the inverter, it is
recommended to lower the ambient temperature before operation.
4. When installing the product in an enclosure, check the closure size and ensure sufficient ventilation.
5. Capacitors and surge suppressors used for improving the inverter's output power factor may be heated
or even damaged because of high-order harmonic components output by the inverter. In addition, when
current overload occurs in the inverter, over-current protection action will be automatically executed.
Therefore, please do not connect capacitors and surge suppressors at the output side of the inverter. To
improve power factor, install the DC reactor at the DC side or AC reactor at the primary side (i.e. input
end) of the inverter.
6. When implementing a megger test, follow the method given in this instruction manual (10-4 ―Megger
Test.‖).
7. When using earth leakage circuit breaker protection switch, select a product for corresponding
high-order harmonic and surge.
8. Please connect directly in principle between the inverter and motor. If you have, such as using a
transformer between the inverter and motor, there is a possibility that an excessive current flow, such as
an inverter / motor may be damaged.
9. Avoid inserting a electromagnetic contactor between the inverter and the motor. If the electromagnetic
contactor is turned on and off while the inverter is operating, an excess current will be generated.
10. Select larger capacity since the operating characteristics of full electromagnetic-type MCCB changes
with higher harmonic current.

3-2 Installation Direction and Space
3-2 Installation Direction and Space
(1) This inverter is of the wall mounting type.
(2) Install the inverter vertically on a flat mounting surface.
(3) Since the inverter generates heat, provide adequate space around it to ensure good heat dissipation
conditions.
(4) When installing the inverter in a control cabinet, provide a ventilation fan to keep the ambient temperature
below 40°C.
(5) When installing the inverter in a control cabinet, mounting the radiator fins outside the control cabinet will
help to reduce the internal temperature of the cabinet.
(6) This inverter is of IP20 structure.
Please select according to intended use.
Figure 3-1 Surrounding Space Figure 3-2Arranging method of radiator fins outside the cabinet
When several inverters are set in a control cabinet, be sure to locate the ventilation fans properly to
allow free air circulation.
If the ventilation fans are located improperly, the ambient temperature will rise and affect the cooling
of the inverter.
