Residual risks
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
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
