● For vertical installation, use all of the eyebolts provided and when necessary, hoisting straps (DIN EN 1492-1) and/or
lashing straps (DIN EN 12195-2) to stabilize the position of the motor.
● Prevent foreign bodies from falling into the fan cover. For vertical machine installation with the shaft end facing
downwards, attach a protective canopy.
● If the shaft extension is facing upwards, the user must prevent liquid from moving along the shaft and entering the motor.
● Clean bare metal surfaces with anti-corrosion agent using white spirit to ensure proper installation and / or machine
mounting.
● Do not obstruct the ventilation! Do not draw in the discharged air directly – also from adjacent equipment.
● 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.
5.3.2 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.
