4.6
Ensure adequate cooling
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 vertical types of machine construction with the air intake from above, protect the air
intakes from the ingress of foreign bodies and water.
•
If the shaft extension is facing upwards, liquid must be prevented from entering by
moving along the shaft.
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.
•
Ensure that the cooling air flow is not reduced as a result of covers and that the
minimum air clearances are maintained.
