fire and smoke. This can result in serious personal injury or property damage.
• Install built-in units in a suitable metal cabinet in such a way that personnel are protected
• Ensure that smoke can only escape via controlled and monitored paths.
Active implant malfunctions due to electromagnetic fields
Converters generate electromagnetic fields (EMF) in operation. Electromagnetic fields may
interfere with active implants, e.g. pacemakers. People with active implants in the immediate
vicinity of an converter are at risk.
• As the operator of an EMF-emitting installation, assess the individual risks of persons with
• Observe the data on EMF emission provided in the product documentation.
Unexpected movement of machines caused by radio devices or mobile phones
Using radio devices or mobile telephones in the immediate vicinity of the components can
result in equipment malfunction. Malfunctions may impair the functional safety of machines
and can therefore put people in danger or lead to property damage.
• Therefore, if you move closer than 20 cm to the components, be sure to switch off radio
• Use the "SIEMENS Industry Online Support app" only on equipment that has already been

motors that have insulation that is not designed for operation with grounded line conductors,
you must perform the following measures:
• IT system: Use a ground fault monitor and eliminate the fault as quickly as possible.
