When installing I/O modules, always observe the special instructions specified in the
corresponding data sheets, e.g., additional fans may be required depending on the module
type.
If processor modules, I/O processing modules or communication modules report that the
temperature limits have been exceeded for a longer period of time, the existing ventilation
concept must be reviewed.
