WARNING
Danger to life through unexpected movement of machines when using mobile wireless
devices or mobile phones
Using mobile radios or mobile phones with a transmit power > 1 W closer than approx. 2 m
to the components may cause the devices to malfunction, influence the functional safety of
machines therefore putting people at risk or causing material damage.
•
When close to components, switch off all wireless devices and mobile phones.
WARNING
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.
WARNING
Danger to life due to fire if overheating occurs because of insufficient ventilation clearances
Inadequate ventilation clearances can cause overheating with a risk for personnel through
smoke development 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
the respective component. They can be found in the dimension drawings or in the
"Product-specific safety instructions" at the start of the respective section.
WARNING
Danger of an accident occurring due to missing or illegible warning labels
Missing or illegible warning labels can result in death or serious injury.
•
Check the warning labels are complete based on the documentation.
• Attach any missing warning labels to the components, in the national language if
necessary.
•
Replace illegible warning labels.
NOTICE
Device damage caused by incorrect voltage/insulation tests
Incorrect voltage/insulation tests can damage the device.
•
Before carrying out a voltage/insulation check of the system/machine, disconnect the
devices as all converters and motors have been subject to a high voltage test by the
manufacturer, and therefore it is not necessary to perform an additional test within the
system/machine.
