16 • The WAGO-I/O-SYSTEM 750Mechanical SetupWAGO-I/O-SYSTEM 750ETHERNET TCP/IP2.6.6 Assembly SequenceAll system components can be snapped directly on a carrier rail in accordancewith the European standard EN 50022 (DIN 35).The reliable positioning and connection is made using a tongue and groovesystem. Due to the automatic locking, the individual components are securelyseated on the rail after installing.Starting with the coupler/controller, the bus modules are assembled adjacentto each other according to the project planning. Errors in the planning of thenode in terms of the potential groups (connection via the power contacts) arerecognized, as the bus modules with power contacts (male contacts) cannot belinked to bus modules with fewer power contacts.AttentionAlways link the bus modules with the coupler / controller, and always plugfrom above.WarningNever plug bus modules from the direction of the end terminal. A groundwire power contact, which is inserted into a terminal without contacts, e.g. a4-channel digital input module, has a decreased air and creepage distance tothe neighboring contact in the example DI4.Always terminate the fieldbus node with an end module (750-600). |
