1.10 Residual Risks
The unavoidable design features of a device, as well as its proper field of application, can also pose risks,
even during correct operation. These residual risks include hazards which, despite the inherently safe
design, existing technical protective equipment, safety precautions and supplementary protective
measures, cannot be ruled out.
Messages on the device and in the Operating Manual warn of residual risks. The consequences of these
residual risks and the measures required to prevent them are listed in the Operating Manual. Moreover,
the operator must take measures to minimize hazards from unavoidable residual risks. This includes, in
particular, issuing operating instructions.
The following list summarizes the hazards against which this Operating Manual and the Service Manual
warn, and specifies protective measures at the appropriate spots:
Unpacking, Transport, Installation
• Sliding or tilting the device
• Setup of the device in unauthorized areas
• Installation of a damaged device
• Installation of a device with damaged power cord
• Inappropriate site of installation
• Missing protective conductor connection
Normal operation
• Assembly errors
• Contact with hot surfaces on the housing
