The PROFIBUS OBTs have two holes. These allow mounting on any flat surface, for example on
the mounting plate of a cabinet.
Drill two holes in the mounting plate as shown in the drilling template in Figure 5-2.
Secure the module with two machine screws (for example M3 x 75 and M3 x 55).
Make sure that there is a reliable electrical connection between the terminal
housing and the grounded mounting plate using a grounding cable of at least 2.5 mm
