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.
Active implant malfunctions due to 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
• Clearly mark the storage locations with the appropriate warning labels.
• IATA regulations must be observed when transported by air.
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
