Fundamental safety instructions
1.1 General safety instructions
Active implant malfunctions due to electromagnetic fields
Inverters 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 inverter are at risk.
• As the operator of an EMF-emitting installation, assess the individual risks of persons
• 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
NOTICE
Damage to motor insulation due to excessive voltages
When operated on systems with grounded line conductor or in the event of a ground fault in
the IT system, the motor insulation can be damaged by the higher voltage to ground. If you
use 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.
• TN or TT systems with grounded line conductor: Use an isolating transformer on the line
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
