4.2.3 Configuration with Active Bus Modules (Installing Active Bus
Modules and 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. Hook the lower edge of the BM PS/IM or BM IM/IM bus module onto the rail,
press it into the rail (a), and push it to the left until it engages (b).
Are you using the 530 mm rail and the BM IM/IM?
If you insert the BM IM/IM in the right latched position, you can install a further
2 PS 307; 2A or 1 PS 307; 5A to the left of the BM IM/IM.
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 so, you must insert
the explosion-proof partition between the modules in the intrinsically safe and
intrinsically unsafe area. To do this, simply insert the explosion-proof partition
on the right-hand side 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 this. 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.
