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 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 store or use the product in a place where
conductive dust, such as iron powder, can enter
through the air inlet/outlet.
Doing so may cause a short circuit, resulting in electric
leakage, 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 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.)
