WARNING
Danger to life from electromagnetic fields
Electromagnetic fields (EMF) are generated by the operation of electrical power equipment, such as transformers,
converters, or motors.
People with pacemakers or implants are at particular risk in the immediate vicinity of this equipment.
If you have a heart pacemaker or implant, maintain a minimum distance of 2 m from electrical power equipment.
•
WARNING
Danger to life from permanent-magnet fields
Even when switched off, electric motors with permanent magnets represent a potential risk for persons with heart
pacemakers or implants if they are close to converters/motors.
If you have a heart pacemaker or implant, maintain a minimum distance of 2 m.
•
When transporting or storing permanent-magnet motors always use the original packing materials with the warning
•
labels attached.
Clearly mark the storage locations with the appropriate warning labels.
•
IATA regulations must be observed when transported by air.
•
WARNING
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 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.
Switch the wireless devices or mobile phones off in the immediate vicinity of the components.
•
WARNING
Danger to life due to the motor catching fire in the event of insulation overload
There is higher stress on the motor insulation through a ground fault in an IT system. If the insulation fails, it is possible that
death or severe injury can occur as a result of smoke 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 of components with subsequent fire and smoke. This can cause
severe injury or even death. 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.
•
WARNING
Danger of an accident occurring due to missing or illegible warning labels
Missing or illegible warning labels can result in accidents involving 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 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.
