10 Mounting
The S-DIAS modules are designed for installation into the control cabinet. To mount the mod-
ules, a DIN-rail is required. The DIN rail must establish a conductive connection with the back
wall of the control cabinet. The individual S-DIAS modules are mounted on the DIN rail as a
block and secured with latches. The functional ground connection from the module to the DIN
rail is made via the grounding clamp on the back of the S-DIAS modules. The modules must
be mounted horizontally (module label up) with sufficient clearance between the ventilation
slots of the S-DIAS module blocks and nearby components and/or the control cabinet wall.
This is necessary for optimal cooling and air circulation, so that proper function up to the
maximum operating temperature is ensured.
