According to the EU machinery directive, machine manufacturers / plant operators must
conduct a risk assessment of their machine. Plant operators must conduct a risk assessment
of their plant. In particular, pay attention to "General Principles" of the EC Machinery
Directive.
Pay attention to the following residual risks:
1.
Unintentional movement 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/cellular phones in the immediate vicinity of the controller
– External influences/damage
2.
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 degree of protection must be installed in an electrical
room or a comparable environment.
3.
Hazardous shock voltages can result from the following causes, for example:
– Component malfunctions
– Influence during electrostatic charging
– Induction of voltages in moving motors
– Operating and/or environmental conditions outside of the specification
– Condensation/conductive contamination
– External influences/damage
