4   Project planning for control and indicating panels 
 
4.2.2  Control room requirements 
The control and indicating panel is to be installed in a controlled environment.  
Permitted ambient conditions:  
Temperature range:   0 °C to +40 °C  
Atmospheric humidity.   <75 %, short-term 95 % without condensation  
Protect the control and indicating panel from harmful environmental influences, such as direct 
sunlight, operation-related vibrations, dust, etc.  
Always ensure adequate heat dissipation before installing the control and indicating panel in a 
recess or other enclosed space or under a cover.  
Ensure that the room is adequately lit (DIN 14675). 
Installation near heating elements or washbasins is prohibited. 
We recommend laying a conductive floor covering (conductive PVC covering, conductive 
needle felt covering) to protect the operating personnel against the unpleasant effects of sta-
tic charging.
