General

The SINAMICS S components are designed in accordance with degree of protection IP20 to
EN 60529 and as open-type devices to UL 50. This ensures protection against electric
shocks. To ensure protection against mechanical stress and climatic conditions too, the
components should only be operated in housing/cabinets/rooms that fulfill at least degree of
protection IP54 and, as enclosure types, are designed to UL 50.
Prefabricated MOTION CONNECT cables are recommended.
The Safety-Integrated safety function:
The components must be protected against conducted contamination (e.g. by installing them
in a cabinet with degree of protection IP54).
Provided that conducted interference can be prevented at the installation site, the degree of
protection for the cabinet can be decreased accordingly.
Low-voltage switchgear and controlgear assemblies
Part 1: Type-tested and partially type-tested low-voltage switchgear 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.
