If a motor holding brake is used, restricted voltage tolerances (24 V ± 10%) may have to be taken into account.
The components must be protected against conductive pollution, e.g. by installing them in a control cabinet with degree
of protection IP54 according to IEC 60529 or Type 12 according to NEMA 250. If conductive pollution can be excluded
at the installation site, a lower degree of cabinet protection may be permitted.
