Handling the product without observing the
instructions that accompany a “Caution” symbol
may result in injury or property damage.
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.
Turn off the power in the event the overheat protection
device (thermal protector) is triggered. Failure to do so may
result in injury or damage to equipment, since the fan will
start abruptly when the overheat protection device (thermal
protector) is automatically reset.
To prevent the risk of electric shock, use the fan for class I
equipment only.

empfehlenswert, um erhöhte Sicherheit zu gewährleisten.
When an abnormality is noted, stop the operation
immediately, or fire, electric shock or injury may occur.
The motor’s surface temperature may exceed
70 °C (158 °F), even under normal operating
conditions. If a fan is accessible during
operation, post the warning label shown in the
figure in a conspicuous position to prevent the
