NOTICE
Risk of corrosion due to condensation
If the machine and/or ambient temperatures fluctuate, this can result in condensation inside
the machine.
• If available, remove the drain plugs or drain screws to drain the water depending on the
ambient and operating conditions.
• If available, re-attach the drain plugs or drain screws.
If the motor is equipped with drain plugs, then the water can drain away by itself.
8.2.1 Safety instructions relating to ventilation and cooling
8.2.1.1 Safety instruction for forced ventilation (option)
Forced ventilation (optional): Type of cooling IC 416 in accordance with EN / IEC 60034-6
WARNING
Risk of burning
Operating the machine without external fan results in overheating. This may result in death,
personal injury and material damage.
• Never commission the machine without an external fan.
8.2.1.2 Safety instructions when operating machines with fan
CAUTION
Risk of injury when touching the fan
There is a risk of injury at machines equipped with a fan cover (e.g. on machines in the textile
industry), as the fan is not completely touch protected.
• Do not touch the rotating fan.
• Do not put your fingers into the larger air discharge openings.
• Prevent manual intervention by using suitable measures, e.g. appropriate housings or a
protective grating.
8.2.1.3 Machines with fan for the textile industry
In order to guarantee an essentially unobstructed flow of cooling air containing fluff, remains of
materials or similar dirt, machines used in the textile industry have a larger air discharge cross-
section between the edge of the cover and the cooling ribs of the machine frame.
