Understand the risks.
The Product generates high-voltage and high-energy.
The product is designed for electrical engineers or the
equivalents who install, wire, and operate it.
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 the AC 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 the AC 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.
Doing so, insulation deteriorates and it may cause
electric shock, fire, or malfunction.
Do not place anything on top of the product.
Doing so, 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 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 or use the product in a place where
corrosive gases or liquids exist in the atmosphere
or conductive dust particles such as iron powder
can enter through the air inlet/outlet.
Deterioration or short-circuiting of its internal parts may
cause leakage of electricity, smoke, burnout, fire, or
malfunction.
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.
Doing so, 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.)

4. Initial Inspection
After unpacking, check its external appearance for any abnormalities.
Check the front panel, rear panel and chassis for scratches, dents, or other damages caused by handling or transportation.
Moreover, check whether or not the encoder or dial on the front panel works correctly as well.
If you find any abnormalities, contact the carrier and us.
