1. Safety Notes
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..

1–3 Notes on Installation
1-3 Notes on Installation
Caution
It is absolutely prohibited to store or use the inverter under the environmental conditions
described below.
Failure to observe this warning may result in a fault, damage, or deterioration, which could lead to fire.
Place becoming high temperature, low temperature, and high humidity out of the environmental
conditions specified in the instruction manual.
In direct sunlight.
Near a heater or other heat source.
In a location subject to vibration or physical shock.
Near machinery that generates sparks
In a location subject to dust, corrosive or inflammable gases, salt, and water droplets.
Outdoors.
Higher than 2000 meters above sea level.
Other similar environments.
Mount the inverter on a metal surface or other non-flammable surface.
Failure to observe this warning may result in a fire.
Install the inverter in a location that can bear its weight.
Failure to observe this warning may result in injury if the inverter falls down.
Do not plug up the air inlet/exhaust. (Refer to ―Installation‖ in the instruction manual for
implementation).
If the air inlet/exhaust is blocked, a fire may be resulted due to internal temperature rise of the
equipment.
Do not place the inverter near flammable materials.
Failure to observe this warning may result in a fire.
Do not allow foreign objects into the inverter or attach to the cooling fans.
Failure to observe this warning may result in a fire or an accident.
Do not operate an inverter which is damaged, lacking parts or dented.
Failure to observe this warning may result in an electric shock, injury, fire or accident.
1-4 Notes on Handling and Moving
Caution
During handling and moving, do not tilt the equipment.
Otherwise, personal injury may be resulted due to falling down of equipment.
Prior to handling and movement, confirm the weight marking attached to the equipment first, if
necessary, please prepare alternative handling machine for work.
Failure to observe this warning may result in personal injury.
Do not fumigate wood packagings which need to disinfect.
Because that Volatile gases and vapors may cause deterioration of electronic components.

1–5 Notes on Wiring
1-5 Notes on Wiring
Danger
Wiring must be performed by qualified personnel.
Failure to observe this warning may result in an electric shock or fire due to incorrect wiring.
Do not connect AC power to an output terminal (U, V, or W).
Failure to observe this warning may result in personal injury or fire.
Do not use if rated voltage is exceeded.
Failure to observe this warning may result in personal injury or fire.
Do not connect a resistor directly to the DC terminals (Pand X).
Failure to observe this warning may result in a fire.
Connection between the ground terminals must be reliable.
Failure to observe this warning may result in electric shock if ungrounded.
For the thickness of grounding wires, please refer to the wire sizes specified in the instruction manual.
Please tighten the terminal block screws according to specified tightening torques.
Failure to observe this warning may result in a fire.
Check that the AC power supply voltage is equal to the rated voltage of the inverter.
Failure to observe this warning may result in personal injury or fire.
For cable types and diameters, please use the cables specified in the instruction manual.
Failure to observe this warning may result in heating or a fire if the diameters of wires are too small.
Secure the inverter before wiring.
Failure to observe this warning may result in electric shock or personal injury.
Caution
The inverter, motor or wiring may cause interference. Please note misoperation of peripheral
devices.
Failure to observe this warning may result in accidents.
If a Residual Current-operated protective Device (RCD) is to be used, it must be an RCD type B.
If the input and output are terminal blocks, the wire heads must be connected with crimp
terminals.
Failure to observe this warning may result in electric shock or fire.
