can be found in the SINAMICS S120 Equipment Manual "Booksize Power Units".
The control and drive components of a drive system are approved for industrial and commercial
use in industrial networks. Their use in public line supplies requires a different configuration
and/or additional measures.
Built-in units from the SINAMICS S series, such as AM600, are designed with degree of
protection IP20 or IPXXB according to IEC 60529 and open type devices according to UL 50.
This therefore ensures that fingers cannot come into contact with any live parts.
To ensure also protection against mechanical stress and climatic conditions, these built-in units
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.
These components may only be handled by qualified and trained technical personnel who are
knowledgeable and observe all of the safety information and instructions on the components
and in the associated technical user documentation.
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.
Converters of the open type / IPXXB 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.
