Warning
• 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, electric shock 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, electric shock
or injury.
• Do not transport, install the product, perform connections
or inspections when the power is on.
Always turn the power off before carrying out these
operations. Failure to do so may result in electric shock.
• To prevent the risk of electric shock, use the fan for class I
equipment only.
Lüfter zur Verwendung in Geräten der Schutzklasse I.
• Install the fan in an enclosure in order to prevent electric
shock or injury.
• Install the fan so as to avoid contact with hands, or ground
it to prevent the risk of electric shock.
Die Gehäuse der Lüfter sind mit einer Schraube und
Zahnscheibe sicher mit dem geerdeten Gehäuse des
Gerätes zu verbinden.
• Keep the input-power voltage within the specified range to
avoid fire and electric shock.
• Connect the cables securely according to the wiring
diagram in order to prevent fire and electric shock.
• Do not forcibly bend, pull or pinch the cable. Doing so may
fire and 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
electric shock or injury. Refer all such internal inspections
and repairs to the branch or sales office from which you
purchased the product.
Caution
• Do not use the fan beyond its specifications, or electric
shock, 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 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 (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 skin burn(s).
• To prevent the risk of damage to equipment, leave nothing
around the fan that would obstruct ventilation.
• 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 gewährleisten.
