WARNING
CAUTION

◆Understand the risk.
Products generate high voltage and energy.
An electrician or equivalent knowledge must read the instruction manual to the end and familiarize yourself
with the proper use and danger of the product.
If you want the product to be handled by another person, limit it to those with knowledge of electricity, and
have people who are familiar with correct use and danger of the product conduct education and training
before handling it, or handle the product under the supervision of those who are familiar with the proper
use and danger of the product. Persons, with the exception of the above, must not handle the product.
◆Do not open the product case and panel.
Do not disassemble, remodel, or repair by opening the product case and panel yourself. There is a high
voltage area inside, which may possibly cause electric shock and fire.
Never remove the case and panel of the product, since the safety and function of the product will not be
guaranteed.
◆It is not suitable for use in places where there is a possibility of a child being present.
The product is designed assuming that it will be used in places where there are only adults, such as
factories and laboratories. Do not use it where there is a possibility of a child being present.
◆Ensure that the product is handled only by a limited number of people.
Only those who are familiar with the proper use and danger of the product, or those who are educated and
trained by them should install the product. Any other person handling the product may cause electric
shock, burns and injuries.
◆Ground it.
When the product has a protective ground terminal or GND terminal, connect it to the ground.
If the input terminal of the product is an inlet type, connect to the power outlet with the ground using the
supplied power cable or a power cable suitable for the area to be used. If it is not connected to the ground,
there is a risk of electric shock and fire, which is extremely dangerous.
◆About power supply cable
If there is a power supply cable attached to the package or product, it cannot be used for other products. In
the case of a product that does not include a power supply cable, you must purchase an optional power
supply cable suitable for the operating environment and the area, or you must prepare it yourself.
◆About the connection of the power supply cable
Connection of the power cable should be done by an electrician or someone who has equivalent
knowledge and is familiar with the correct usage and danger of the product. Refer to the page about
connection of the input cable in the instruction manual and carry out work. For products that have acquired
safety standards, also refer to the page that describing overvoltage categories.
◆About input voltage
For the input voltage of the product, refer to the page describing the input terminal of the product and the
input voltage in the instruction manual. Do not supply input exceeding the specifications of the product.
◆About the fuse
The product contains a protective fuse. In the case of a product in which a fuse holder is arranged
externally, it is possible to replace the fuse. For the replacement method, refer to the instruction manual.
If the product does not have a fuse holder externally, the user cannot replace the fuse. If the fuse blows out,
do not open the case or panel. Please contact our sales representative.
◆Do not modify or damage the cable.
It may cause electric shock and fire.
WARNING

◆Designed for indoor use
Use the product indoors. Do not use it outdoors or indoors where there is a possibility of water leakage,
flooding, or crown.
◆About operating temperature and humidity
Use within the range of operating temperature and humidity stated in the instruction manual.
Do not use it in a place where the ambient temperature becomes higher than the operation temperature of
the product or in a narrow closed place.
◆Do not install in places that cause condensation.
Do not install it in places that cause condensation, where it is exposed to steam or water vapor.
Insulation deteriorates, causing breakdown, electric shock, or fire.
◆Do not place anything on top of the product.
Falling or collapsing is dangerous.
◆Do not put any objects on or in the product.
Do not put any objects such as metal or liquid in the product through the inlet etc. Failure, electric shock,
fire may result.
◆Operate the product with your right hand.
In case of electric shock when manipulating the product, in order to reduce the risk of current flowing
through important organs of the body. Keep your left hand off from the product and operate with your right
hand.
◆Do not touch the wiring or load connected to the output terminal or output terminal during
operation or immediately after output stop.
Very high voltage is applied to the terminals during normal operation and trial operation.
Touching it will result in electric shock.
In addition, since a capacitor is connected to the terminal, high voltage remains on the terminal even
immediately after stopping the output. To avoid electric shock, do not touch the terminals.
◆Turn off the power when touching the terminal.
Before touching the terminals of the product, turn off the power and check that the power has actually
turned off.
There is a capacitor at the terminal, and it is particularly dangerous to touch it immediately after turning off
the power supply. Be careful of the electric charge of these capacitors and connect it to earth to discharge
it completely. Remove input line (AC line) during work.
WARNING

◆Install horizontally.
Do not install the product in the reverse direction and the lateral direction. Internal heat dissipation
becomes insufficient, parts deteriorate, there is a risk of smoke and fire.
◆Do not install in the place where cool air blows directly.
There is a danger of condensation, leakage current and burnout.
◆Do not install the product in places around corrosive gas or liquid and places where chemicals
handled.
There is a danger of parts being deteriorated, smoking and burning.
◆Avoid using it in a place with much dust.
If dust accumulates in the air inlet, remove it promptly.
If dust accumulates in the air inlet, cooling of the product is hindered and it may cause malfunction.
◆Do not block intake port and exhaust port.
Secure more than 30cm space on the front and back of the product.
If the intake port and exhaust port are blocked, the specified performance of the product cannot be
demonstrated and parts are deteriorate, which may cause smoke and fire.
◆When work such as welding is conducted near the product, disconnect all the wires from the
product.
◆Do not wipe with chemicals (thinner etc.) or wet cloth.
There is a danger of electric shock, electric leakage, burnout from chemicals or water entering the inside of
the product.
◆About fan replacement
In the case of products with air-cooling fans, the fan has a lifetime part. As wear, deterioration, etc.
progress with the lapse of use time, operation may become unstable. Also note that the lifetime of fan
varies greatly depending on the environment where it is used (temperature, humidity, dust, etc.). In order
to use the product for a longer time, it is necessary to replace the fan periodically. For replacement, please
contact our sales office (replacement require separate repair charges). Do not exchange fans with other
users because there is a danger of electric shock, etc.

1-5 Installation conditions
Warning
•Use this equipment within the range of 0 to 40°C, 20 to 80%RH.
•Do not install in the following environment.
•Places with a high-temperature, high-humidity
•Places where there are a lot of explosives, flammable gas, corrosive gas, etc.
•Places with a lot of dust, combustible materials
Caution
•Use this equipment in a stable and horizontal location.
•Never place any article on this equipment.
•For the models in natural cooling type, since air flows from the bottom face and side faces to the
upper face, never place any article on the upper face.
•Do not use the power supply unit of this series in a piled-up state.
•Use this equipment in an environment with good ventilation, as much as possible. When used while
integrated inside other equipment, or while the periphery of this equipment is fully enclosed or under
similar conditions, take countermeasures against bad ventilation such as forced air cooling, etc., and
use within the range of 0 to 40°C, 20 to 80%RH.
•For the forced air cooling type, keep a space of 30 cm or more at the front and back sides of the main
unit of power supply.
•Do not clog the suction hole or exhaust hole of this equipment.
•When dust accumulates at the suction hole, remove it promptly. It will interfere with cooling of the
power supply unit.
1-6 Precautions for handling
Warning
•Input voltage shall be ±10% of the input voltage value indicated on the rear panel, and 50 Hz/60 Hz.
