5.3.3 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 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.
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).
● Ensure that the cooling air flow is not reduced as a result of covers and that the minimum
air clearances are maintained.
