Note
Remove the transport protective foil and packaging material before installing the components.
5.2.2
Operating conditions
The components of the SINUMERIK MC system are intended for a weatherproof, fixed
location. The documented environmental conditions apply to the climate in the immediate
vicinity of the units and to the entry of the cooling air. They exceed the requirements according
to EN 60204-1, EN 61800-2, EN 61131-2 and IEC 62477-1.
