Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile wireless devices or mobile phones with a transmitter power > 1 W closer than
approx. 2 m to the components may cause the devices to malfunction and influence the
functional safety of machines, therefore putting people at risk or causing material damage.
• Switch the wireless devices or mobile phones off in the immediate vicinity of the
Danger to life due to the motor catching fire in the event of insulation overload
There is a greater load on the motor insulation through a ground fault in an IT system. A
possible result is the failure of the insulation with a risk for personnel through smoke
development and fire.
• Use a monitoring device that signals an insulation fault.
• Correct the fault as quickly as possible so the motor insulation is not overloaded.
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk to personnel due to
smoke and fire. This can also result in increased downtime and reduced service lives for
devices / systems.
• Ensure compliance with the specified minimum clearance as ventilation clearance for
Danger of an accident occuring due to missing or illegible warning labels
Missing or illegible warning labels can result in death or serious injury.
• Check that the warning labels are complete based on the documentation.
• Attach any missing warning labels to the components, in the national language if
• Replace illegible warning labels.
