2.6.6 Assembly Sequence 
All system components can be snapped directly on a carrier rail in accordance 
with the European standard EN 50022 (DIN 35). 
The reliable positioning and connection is made using a tongue and groove 
system. Due to the automatic locking, the individual components are securely 
seated on the rail after installing. 
Starting with the coupler/controller, the bus modules are assembled adjacent to 
each other according to the project planning. Errors in the planning of the node 
in terms of the potential groups (connection via the power contacts) are 
recognized, as the bus modules with power contacts (male contacts) cannot be 
linked to bus modules with fewer power contacts. 
Attention 
Always link the bus modules with the coupler/controller, and always plug 
from above. 
Warning 
Never plug bus modules from the direction of the end terminal. A ground 
wire power contact, which is inserted into a terminal without contacts, e.g. a 
4-channel digital input module, has a decreased air and creepage distance to 
the neighboring contact in the example DI4. 
Always terminate the field bus node with an end module (750-600).
