● Avoid exposing them to direct, intense solar radiation, rain, snow, ice, or also dust for
extended periods. Attach a covering structure or an additional cover when using or
storing outdoors.
● Do not exceed the permissible axial and radial forces.
● Check for vibration caused by fan reaction or resonance points at the installation location
corresponding to ISO 10816 over the complete speed range.
5.4.2 Cooling
5.4.2.1 Ventilation
WARNING
Overheating and failure of the motor
Death, severe injury or material damage can occur if you do not carefully observe the
following points.
• Do not obstruct ventilation.
•
Prevent the air expelled by neighboring equipment from being immediately sucked in
again.
• For machines with a vertical type construction with air entry from above, prevent the
ingress of foreign bodies and water in the air entry openings (standard IEC / EN 60079-
0).
•
If the shaft extension is facing upwards, liquid must be prevented from entering by
moving along the shaft.
5.4.2.2 Safety instructions regarding types construction/mounting type
WARNING
Damage caused by small parts falling in
Material damage and injury can occur if the fan is destroyed and therefore the motor
overheats.
•
For types of construction with the shaft extension facing downwards, prevent small parts
from falling into the fan cover by providing suitable covers (standard IEC / EN 60079-0).
• Prevent the cooling airflow from being reduced as a result of covers that might be in
place.
