4.5.5.3 Regreasing rolling bearings after storage periods of up to two years
• For machines with regreasing systems, briefly lubricate both bearings after commissioning
with the machine running as a precautionary measure.
• Grease type, grease quantity and relubrication intervals for the regreasing system are
stamped on the rating plate attached to the machine.
4.5.5.4 Releasing the rotor shipping brace before commissioning
If one is being used, release the rotor shipping brace before commissioning.
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.
For machines with external fans, install an interlock circuit that prevents the main machine
being switched on if the external fan is not operational.
