3.6 Cabinet design and air conditioning
The modular concept of SINAMICS Chassis units allows for a wide range of different device combinations. Therefore
a description of each individual combination cannot be provided here. In a similar way to the chapter "EMC
Installation Guideline", this section simply aims to explain fundamental principles and general rules which can help to
ensure that cabinets are designed with adequate air conditioning so that they will function reliably and safely.
In addition, adequate room air conditioning at the installation site must be provided (capacity of air conditioning
system, required volumetric flow).
The various local regulations and standards must also be observed. You are advised to carefully observe the
information provided in the safety instructions, which can be found in the manuals and the documents accompanying
the components supplied.
3.6.1 Directives and standards
The table below provides a list of key directives and standards which form the basis for designing safe, reliable and
EMC-compliant SINAMICS drive systems.
