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.
