Unexpected movement of machines caused by radio devices or mobile phones
When radio devices or mobile phones with a transmission power > 1 W are used in the
immediate vicinity of components, they may cause the equipment to malfunction.
Malfunctions may impair the functional safety of machines and can therefore put people in
danger or lead to property damage.
• If you come closer than around 2 m to such components, switch off any radio devices or
mobile phones.
• Use the "SIEMENS Industry Online Support App" only on equipment that has already
been switched off.
Fire due to inadequate 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.
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
• Check that the warning labels are complete based on the documentation.
• Attach any missing warning labels to the components, where necessary in the national
language.
• Replace illegible warning labels.
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 inverters 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.
