Siemens Sinamics G110M Original Instructions Manual page 20

Fundamental safety instructions
1.5 Residual risks of power drive systems
Note
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.
For more information about residual risks of the components in a drive system, see the
relevant sections in the technical user documentation.
