Safety information

1.4 Residual risks of power drive systems

1.4

Residual risks of power drive systems

The control and drive components of a drive system are approved for industrial and

commercial use in industrial line supplies. Their use in public line supplies requires a

different configuration and/or additional measures.

These components may only be operated in closed housings or in higher-level control

cabinets with protective covers that are closed, and when all of the protective devices are

used.

These components may only be handled by qualified and trained technical personnel who

are knowledgeable and observe all of the safety instructions on the components and in the

associated technical user documentation.

When assessing the machine's risk in accordance with the respective local regulations (e.g.,

EC Machinery Directive), the machine manufacturer must take into account the following

residual risks emanating from the control and drive components of a drive system:

1. Unintentional movements of driven machine components during commissioning,

operation, maintenance, and repairs caused by, for example:

– Hardware defects and/or software errors in the sensors, controllers, actuators, and

– Response times of the controller and drive

– Operating and/or ambient 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. In the event of a fault, exceptionally high temperatures, including an open fire, as well as

emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,

e.g.:

– Component malfunctions

– Software errors

– Operating and/or ambient conditions outside 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.
