8.1.1 Safety instructions relating to ventilation and cooling
8.1.1.1 Forced ventilation (optional): Cooling method IC 416 in accordance with
EN / IEC 60034-6
Explosion hazard if the temperature class is exceeded
If a force-ventilated machine is operated without a separately driven fan, the temperature
class or the maximum surface temperature of the machine can be exceeded.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
● Install an interlock circuit that prevents the machine from being switched on if the
separately driven fan is not switched on/is not operational.
● Do not commission the machine without a separately driven fan.
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.
8.1.2 Switching on with the anti-condensation heating active
Excessively high machine temperature when heating is switched on
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine. Material damage can result.
● Make sure that the anti-condensation heating is switched off before the machine is
switched on.
● Only operate anti-condensation heating when the machine is switched off.
