5.2.2 Operating conditions
The components of the SINUMERIK ONE system are intended for a weatherproof, xed location.
The documented ambient conditions apply to the climate in the immediate vicinity of the units
and to the entry of the cooling air. The following standards are complied with: EN60204-1,
EN61800-2, EN61131-2 and IEC62477-1.
