Read the instruction manual thoroughly before use and familiarize yourself with the proper use and

danger of the product.

Make sure to allow only specific people to handle the product.

Make sure to allow only the following people to handle the product:

1. who are electrical engineers or the equivalents and have already familiarized themselves with the

proper use and danger of the product, or

2. who are electrical engineers or the equivalents and have already been trained by the above-mentioned

people, or

3. who work under the supervision of the above-mentioned people.

If people other than those listed above install, wire, or operate the product, it may cause electric

shock, burnout, or injury.

Do not open or remove the case or panel of the product.

Do not disassemble, repair, or modify the product by yourself. High-voltage is applied to the inside of it.

Otherwise, it may cause electric shock, fire, or malfunction.

Moreover, if you do it, the safety and functions are not covered with the warranty.

The product does not suit to install and use in places where children may be present.

The product is designed to be installed in places such as factories or laboratories. Do not install and use it

where children may be present.

Make sure to ground it.

When the product has a protection ground terminal or GND terminal, make sure to ground it.

When theAC line input of it is an inlet type, connect the attached power cable or a power cable suitable for

your area to an outlet with the ground. Otherwise, it may result in electric shock or fire.

Regarding power cable

When a power cable is enclosed or attached to the product, do not use it for other products.

When no power cable is enclosed with the product, prepare the power cable suitable for the usage

environment and area by yourself.

Regarding the connection of power cable

Electrical engineers or the equivalents who have already been familiarized with the proper use and danger

of the product should connect the power cable to theAC input by referring to the instruction manual.

Regarding products that have acquired the safety standard, check the page describing the over-voltage

categories too.

Do not process or damage power cables

It may result in electric shock or fire.

Regarding the input voltage

Check the page describing the input terminals and input voltage in the instruction manual.

Do not provide any voltage out of the specifications.

Regarding the fuse

The product builds in a protective fuse. In the case where a fuse holder is arranged outside of the product,

you can replace it by yourself. Refer to the instruction manual to replace it.

In the case where a fuse holder is not arranged outside of the product, you cannot replace it by yourself.

In this case, do not open the case or panel of the product and contact us.

The product is designed for indoor use.

Use the product indoors only, not outdoors. Even indoors, do not use it if there is a possibility of water

leakage, flooding, or snow covering.

Regarding operating temperature and humidity

Use the product within the range of the specifications describing in the instruction manual.

Do not use it in a place where the ambient temperature exceeds the specified range or a closed place.

Do not install the product in places where condensation may occur.

Otherwise, insulation deteriorates and it may cause electric shock, fire, or malfunction.

Do not place anything on top of the product.

Otherwise, they may fall or tumble from it.

Do not put anything into the product.

Do not put foreign objects such as metal or liquid into the product through the air inlets, air outlets, or other

openings. Otherwise, it may result in electric shock, fire, or malfunction.

Operate the product with the right hand.

Use only your right hand to operate the product and keep your left hand away from it, which can reduce

the risk of electric current flowing through the left hand to the vital organs of the body in the event of an

electric shock.

Do not touch the wiring/load connected to the output and any terminals/connectors during the

operation or just after turning output off.

Very high-voltage is on the terminals and connectors during the operation and even just after the output is

turned off. Touching them may result in serious injury or death by electric shock.

The terminals here mean all terminals like input and output terminals and terminals for communications

and remote controls.

Turn off the product before touching the wiring/load connected to the product and any

terminals/connectors on the product and cut it off from the AC input.

Before touching the terminals/connectors and wiring/load, turn off the product and unplug the AC input

cable from the outlet or turn off the AC input breaker. Then, check there is no voltage remained using a

tester.

Since the output and sense terminals are connected to condensers in it, there is high-voltage remained on

them even just after it is turned off.

In order to avoid electric shock, ground the terminals to discharge using a short-circuit grounding

apparatus and check the voltage again.

The terminals here mean all terminals like input and output terminals and terminals for communications

and remote controls.

Level the product out to use for good heat dissipation.

Do not install the product upside down or sideways. If not, the inner heat dissipation will be insufficient.

It may result in smoke or fire due to components deterioration.

Do not install the product in a place where cold air directly blows to it.

It may result in electric leakage or burnout due to condensation.

Do not install the product in a place where it is exposed to corrosive gases or liquids.

It may result in smoke or burnout due to components deterioration.

Do not install the product in a dusty place.

Accumulating dust in the air inlet will make hard to cool it down it, it may result in malfunction.

In that case, remove dust immediately.

Do not block the air inlet and outlet.

Secure 30 cm space at least around the openings.

If they are blocked, the product cannot show the rated performance due to the internal temperature

increase. Moreover, components deteriorate and it may result in smoke or fire.

Remove wiring to and from the product when work like welding near it is done.

Do not wipe the equipment with a dust cloth wet with chemicals (thinner or the like) or water.

Otherwise, it may result in an electric shock, electric leakage, or burnout due to water getting inside.

Regarding fan replacement

When products equip a fan, it has a lifetime. It will be worn out and deteriorated with the time passed and

its operation may become unstable. Also, its lifetime greatly varies depending on the usage environment

such as temperature, humidity, dust. It requires to be replaced at regular intervals to extend the lifetime.

For the replacement, contact us.

(It requires a replacement charge separately. Do not replace it by yourself, as there is a risk of electric

shock.)
