General information

SINAMICS S components fulfill the requirements according to degree of protection IP20 in
compliance with EN 60529. This provides protection against electric shock for chassis units.
As far as UL 50 is concerned, the components are classified and certified as open type.
Protection against mechanical and climatic stressing must be ensured by mounting the
components in housings, cabinets or electrical rooms that can be closed and locked. Higher-
level housings must, as a minimum, have degree of protection IP54 according to EN 60529
be classified as enclosure type 12 in compliance with UL 50.
Prefabricated MOTION-CONNECT cables are recommended.
The Safety-Integrated safety function:
The components must be protected against conductive pollution (e.g. by installing them in a
cabinet with degree of protection IP54B acc. to EN 60529).
Provided that conductive pollution can be prevented at the installation site, the degree of
protection for the cabinet can be decreased accordingly.
Low-voltage switchgear and controlgear assemblies
If the SINAMICS S drive line-up is used for the electrical equipment of machines, the
applicable requirements of EN 60204-1 must also be adhered to.
