Pay attention to the following residual risks:
● Unintentional movements of driven machine parts
Unintentional movements of driven machine parts can occur during commissioning,
operation, maintenance, and repair, e.g. from the following causes:
– Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
– Response times of the controller and drive
– Operating and/or environmental conditions outside of the specification
– Condensation/conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of radio devices/cell phones in the immediate vicinity of the controller
– External influences/damage
● High temperatures and emissions
A fault can occur as a result of the following, for example:
– Component malfunctions
– Software errors
– Operating and/or environmental conditions outside of the specification
– External influences/damage
A fault can, for example, have the following consequences both inside and outside the drive:
– Extraordinarily high temperatures, including open fires as a result of the fault
– Emissions of light, noise, particles or gases
Converters with open type/IP20 protection must be installed in a distribution station or
comparable environment.
● Hazardous shock voltages
Hazardous shock voltages can result from the following causes, for example:
– Component malfunctions
– Induction of voltages in moving motors
– Operating and/or environmental conditions outside of the specification
– Condensation/conductive contamination
– External influences/damage
● The release of substances and emissions that are harmful to the environment
Improper operation or the improper disposal of components can harm the environment.
