Hello Edmund; Mounted horizontally, with sufficient space beow and above to allow convective cooling (> 25 mm), all S7-200 CPUs are designed to operate in a range of 0 to 55 °C. A vertical installation reduces this range by 10°C. Not enough surrounding space will make these ranges unworkable. See the technical data in the S7-200 System manual, as well as installation recommendations: https://support.industry.siemens.com/cs/ww/en/view/1109582 Hope this helps, |
