1. Unintentional movements of driven machine components during commissioning, operation,
maintenance, and repairs caused by, for example:
– Hardware faults and/or software errors in sensors, controllers, actuators, and connection
systems
– Response times of the controller and drive
– Operating and/or ambient conditions not within the scope of the specification
– Condensation / conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of radio devices / cellular phones in the immediate vicinity of the controller
– External influences/damage
2. In the event of a fault, exceptionally high temperatures, including open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the converter,
e.g.:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions not within the scope of the specification
– External influences/damage
Inverters of the Open Type/IP20 degree of protection must be installed in a metal control
cabinet (or protected by another equivalent measure) such that the contact with fire inside
and outside the inverter is not possible.
3. Hazardous shock voltages caused by, for example:
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operating and/or ambient conditions not within the scope of the specification
– Condensation / conductive contamination
– External influences/damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a risk
to people with a pacemaker, implants or metal replacement joints, etc. if they are too close
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).
