Installing Active Bus Modules And Modules (Configuration With Active Bus Modules) - Siemens SIMATIC ET 200M Operating Instructions Manual

4.2.4 Installing Active Bus Modules and Modules (Configuration with Active Bus
Modules)
Installing Bus Modules and Modules
To install the active bus modules and modules, proceed as follows:
Only install the active bus modules in a de-energized state.
1. Suspend the bus module BM PS/IM or BM IM/IM with the lower edge in the rail, press it into
the rail (a) and slide it to the left until the latched position (b).
Do you use the 530 mm rail and the BM IM/IM?
If you position the BM IM/IM in the right of the two latched positions (1), to the left
alongside the BM IM/IM you can still install either 2 x PS 307; 2A or 1 x PS 307; 5A.
2. Hook the next bus module (bus module BM 2 40 or BM 1 80) onto the rail and push it onto
the rail. Push it towards the left bus module, so that the module connector has contact.
3. Are you installing the ET 200M in intrinsically safe areas?
If yes, then you require the explosion-proof partition between the modules in the
intrinsically safe and the non-intrinsically safe areas. To do this, simply insert the
explosion-proof partition on the right lateral guide of the bus module.
4. Hook the modules onto the rail and swing them down into place. Use the side guides of the
bus modules to do so. When you screw in the modules, fix the bus module to the rail at the
same time
5. Plug the bus module cover onto the last bus module. If there is a slot with no module, plug
in the backplane bus cover on the unoccupied slot.
