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.
