Safety Note For Ventilation; Forced Ventilation (Optional): Cooling Method Ic 416 In Accordance With En / Iec 60034-6 - Siemens SIMOTICS XP Operating Instructions Manual

Risk of explosion due to static charging
If you clean the motor, plastic components may become statically charged and ignite a
potentially explosive atmosphere. An explosion can occur. This can result in death, serious
injury or material damage.
• When cleaning ensure that there is absolutely no explosive atmosphere present.
• Clean the plastic parts and components so that absolutely no static charging occurs
• Do not use compressed air for cleaning.

Safety note for ventilation

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
