•Do not use the product in explosive or corrosive environments, in the
presence of ammable gases, locations subjected to splashing water,
or near combustibles. Doing so may result in re or injury.
•Assign qualied personnel the task of installing, wiring, operating/
controlling, inspecting and troubleshooting the product. Failure to do
so may result in re or injury.
•Shut off the power to the fan in the event the lock-protection circuit is
activated. Otherwise, the fan will start unexpectedly when released
from the locked condition, causing bodily injury or equipment
damage.
•Install the fan in an enclosure in order to prevent injury.
•Keep the input-power voltage within the specied range to avoid re.
•Connect the cables securely according to the wiring diagram in order
to prevent re.
•Do not forcibly bend, pull or pinch the cable. Doing so may re.
•For the power supply use a DC power supply with reinforced
insulation on its primary and secondary sides. Failure to do so may
result in electric shock.
•Turn off the power in the event of a power failure, or the fan will
suddenly start when the power is restored and may cause injury or
damage to equipment.
•Do not disassemble or modify the fan. This may cause injury.
Refer all such internal inspections and repairs to the branch or sales
ofce from which you purchased the product.
•Do not use the fan beyond its specications, or injury or damage to
equipment may result.
•Keep your ngers and objects out of the openings in the fan. This
may cause injury.
•Do not touch the motor during operation or immediately after
stopping. The surface is hot and may cause a skin burn(s).
•Do not hold the rotating parts (runner) of the fan or lead wire. This
may cause injury.
•Keep the area around the fan free of combustible materials in order
to prevent re or a skin burn(s).
•To prevent the risk of damage to equipment, leave nothing around
the fan that would obstruct ventilation.
•Provide anti-static measures before installing the fan. Failure to do
so may result in equipment damage.
•Do not touch the rotating parts (runner) when the fan is in operation.
This may cause injury. The use of the optional ngerguard is
recommended to ensure protection.
•Immediately when trouble has occurred, stop running and turn off the
fan power. Failure to do so may result in re, electric shock or injury.
•Dispose the product correctly in accordance with laws and
regulations, or instructions of local governments.

Installation
Location for installation
Install it in a well-ventilated location that provides easy access for
inspection. The location must also satisfy the following conditions:
•Inside an enclosure that is installed indoors
•Operating ambient temperature
–10 to +60 °C (+14 to +140 °F) (non-freezing)
•Operating ambient humidity 85% or less (non-condensing)
•Area that is free of explosive atmosphere or toxic gas (such as
sulfuric gas) or liquid
•Area not exposed to direct sun
•Area free of excessive amount of dust, iron particles or the like
•Area not subject to splashing water (rains, water droplets), oil (oil
droplets) or other liquids
•Area not subject to continuous vibration or excessive shocks
•Area free of radioactive materials, magnetic elds or vacuum
•Area free of excessive electromagnetic noise (from welders, power
machinery, etc.)
When using near a switching circuit or high-frequency power supply,
the induced current may ow inside the fan due to electromagnetic
noise (conductive noise, radiative noise). If the induced current ows,
the electric corrosion is caused in the bearings of the fan. As a result,
it may generate the noise or shorten the service life of the products.
Use the fan in the environment that the electromagnetic noise does
not cause.
