Safety precautions
The precautions described below are intended to prevent danger or
injury to the user and other personnel through safe, correct use of
the product. Use the product only after carefully reading and fully
understanding these instructions.
Warning
Handling the product without observing the instructions that
accompany a “Warning” symbol may result in serious injury or death.
• Do not use the product in explosive or corrosive environments, in
the presence of flammable gases, locations subjected to splashing
water, or near combustibles. Doing so may result in fire or injury.
• Assign qualified personnel the task of installing, wiring,
operating/controlling, inspecting and troubleshooting the product.
Failure to do so may result in fire 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 specified range to avoid
fire.
• Connect the cables securely according to the wiring diagram in
order to prevent fire.
• Do not forcibly bend, pull or pinch the cable. Doing so may fire.
• 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 office from which you purchased the product.
Caution
Handling the product without observing the instructions that
accompany a “Caution” symbol may result in injury or property
damage.
• Do not use the fan beyond its specifications, or injury or damage
to equipment may result.
• Keep your fingers 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 fire 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
fingerguard is recommended to ensure protection.
Wegen der Verletzungsgefahr dürfen die Lüfterflügel 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
fire or injury may occur.
• 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 fields 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 flow inside the fan due to
electromagnetic noise (conductive noise, radiative noise). If the
induced current flows, 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 flat metal plate having excellent
vibration resistance and heat conductivity. Drill holes on the
mounting plate and fix 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 flow 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 off the power to
the fan before performing an inspection.
