Protection against the spread of fire
The converter may be operated only in closed housings or in higher-level control cabinets
with protective covers that are closed, and when all of the protective devices are used.
Converters of the Open Type/IP20 degree of protection must be installed in a metal control
cabinet or protected by another equivalent measure such that fire cannot spread and
emissions outside of the control cabinet are prevented.
Protection against condensation and electrically conductive contamination
To ensure the functional safety and safety functions of Safety Integrated, protect the
converter, e.g. by installing it in a control cabinet with degree of protection IP54 according to
IEC 60529 or Type 12 according to NEMA 250. Further measures may be necessary for
particularly critical operating conditions.
If condensation and conductive pollution can be excluded at the installation site, a lower
degree of cabinet protection may be permitted.
The switchgear cabinet must satisfy the following EC Directives in the European Economic
