Cabinet design and EMC Booksize
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 ensures protection
against electric shocks.
To ensure also protection against mechanical stress and climatic conditions, the components
must always be operated in housings, cabinets or enclosed electrical operating areas/rooms
that fulfill at least 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 onl
y 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/IPXXB degree of protection must be installed in a metal control
cabinet or protec
ted by another equivalent measure such that fire cannot spread and
emissions cannot escape from the cabinet.
Note
Protection against condensation and electrically conductive contamination
To ensure the functional safety and safety functions of Safety I
ntegrated, 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.
sation and conductive pollution can be excluded at the installation site, a lower
degree of cabinet protection is permissible.
Low-voltage switchgear and controlgear assemblies
If the SINAMICS S drive line-up is used for the electrical equipment of machines, the
applicable requirements of EN 60204-1 must also be adhered to.
