General information
SINAMICS S components are available as chassis units with degree of protection IP20 or IPXXB
according to IEC 60529 and as open type devices to UL 50. This therefore ensures that fingers
cannot come into contact with any active components.
To also ensure protection against mechanical stress and climatic conditions, the components
must always be operated in housings, cabinets or enclosed electrical areas/rooms that as a
minimum fulfill degree of protection IP54 according to European enclosure specifications, or in
compliance with US, Canadian and Mexican regulations, as enclosure type 12 according to
NEMA 250.
Note
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.
The installation of the converter with open type / IPXXB degree of protection in a metal control
cabinet or protection implemented with another equivalent measure must prevent the
propagation of fire and emissions outside the control cabinet.
Note
Protection against condensation and electrically conductive pollution
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.
A lower degree of cabinet protection is permissible if condensation and conductive pollution can
be excluded at the installation site.
Low-voltage switchgear and controlgear assemblies
If the SINAMICS S drive lineup is used for the electrical equipment of machines, the applicable
requirements of EN 60204-1 must also be adhered to.
