WARNING
•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 qualied personnel the task of installing, wiring, operating/
controlling, inspecting and troubleshooting the product. Failure to do so
may result in re or injury.
•Shut o 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 specied 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 o 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 oce from which
you purchased the product.
CAUTION
•Do not use the fan beyond its specications, 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 hold the rotating parts (blades) 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 burn.
•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 (blades) when the fan is in operation. This
may cause injury. The use of the optional ngerguard is recommended to
ensure protection.
Wegen der Verletzungsgefahr dürfen die Lüfterügel bei Ventilatorbetrieb
nicht berührt werden. Der Gebrauch des als Sonderzubehör erhältlichen
Fingerschutzes ist empfehlenswert, um erhöhte Sicherheit zu ewährleisten.
•When an abnormality is noted, stop the operation immediately, or re or
injury may occur.
•Dispose the product correctly in accordance with laws and regulations, or
instructions of local governments.
Preparation
Verify the model number of the purchased product against the number
shown on the package label. The fan model name is listed on the fan
nameplate.

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.
How to install the fan
Install the fan onto an appropriate at metal plate having excellent vibration
resistance and heat conductivity. Drill holes on the mounting plate and x
the fun on the plate using screws (not supplied). For air orientation and
rotational direction, see the indications shown on the fan’s side frame.

Note The stall alarm type of fan is not equipped with a delayed trip-
point alarm circuit. Therefore, an external delay function is
necessary to avoid the detection of fan start.
The set time of the delay function should be at least one second.
Overheat protection
The fan is equipped with an internal protective circuit against overheating. In
the event a lock-up condition is detected, this function automatically controls
the current ow to the fan motor’s windings, thus preventing the fan blades
from locking and burning out. The fan resumes operation automatically as
soon as it is released from the locked condition. Be sure to shut o the power
to the fan before performing an inspection.
