Siemens SIMATIC NET PROFIBUS manual Installation on a Mounting Plate

Installation and Startup

Installation on a Mounting Plate

PROFIBUS OBTs have two holes drilled in them. This allows them to be installed on any flat surface, for example on the mounting plate of a cubicle.

SDrill two holes in the mounting plate as shown in the drill template in Figure 5-2.

SSecure the modules with machine screws (for example M3 x 75 and M3 x 55).

SUse a grounding conductor with at least 2.5 mm2 to establish a reliable electrical connection between the PE terminal of the module casing and the grounded mounting plate.
