You must maintain the clearance shown in the figure in order to provide sufficient
space to install the modules and to dissipate the heat generated by the modules.
The S7-300 assembly on multiple racks shown in the figure below specifies the
clearance between racks and adjacent components, cable ducts, cabinet walls etc.
For example, if you wire your modules using a cable duct, the clearance between
the bottom edge of the shielding contact element and the cable duct must be 40
mm.
