Safety information
2.8 Residual risks
Pay attention to the following residual risks:
● Unintentional movements of driven machine parts
● High temperatures and emissions
● Hazardous shock voltages
● The release of substances and emissions that are harmful to the environment
20
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
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
For instance, a fault can have the following effects:
– Extraordinarily high temperatures, including open fires as a result of the fault
– Emissions of light, noise, particles or gases
Devices with "Open Type/IP20 degree of protection" must be installed in an electrical room
or a comparable environment.
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
Improper operation or the improper disposal of components can harm the environment.
