General information
The S120 Combi Power Modules fulfill the requirements according to degree of protection
IP20 in compliance with EN 60529. This provides protection against electric shock for built-in
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 installing the
modules in enclosures, cabinets or electrical rooms that can be closed and locked. Higher-
level enclosures must, as a minimum, have degree of protection IP54 according to EN 60529
or be classified as enclosure type 12 in compliance with UL 50.
Prefabricated MOTION-CONNECT cables are recommended.
Note
Functional safety of SINAMICS components
The components must be protected against conductive pollution. This can be achieved e.g.
by installing them in a control 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 S120 Combi is used for the electrical equipment of machines, the applicable
requirements of EN 60204-1 must also be adhered to.
