In addition to their own accessories, Siemens AG is also offering high-quality accessories
from well-known manufacturers as commercial goods. Commercial goods are qualified in a
brief power-up test but do not go through the system test of the Siemens AG. The technical
properties of commercial goods can deviate from the properties guaranteed by comparable
products of the Siemens AG. Commercial goods are identified as such in the online catalog
of the Siemens AG. Technical specifications, drivers, certificates, test verification documents,
etc. are supplied by the respective manufacturer to Siemens AG and are also available for
download in the online catalog or technical support of the Siemens AG.

The degree of protection specifies a standard of electronic equipment for a variety of
ambient conditions – and the protection of humans against potential danger when using this

classifies the protection of equipment against dirt and moisture.
Defines whether a system alarm is displayed on the HMI device and the duration of the
display.
Electromagnetic compatibility (EMC) refers to a usually desirable state, in which technical
equipment does not disturb one another with unwanted electrical or electromagnetic effects.
Electromagnetic compatibility deals with technical and regulatory questions of undesired,
mutual influence in electrical engineering.
