Due to the automatic locking, the individual components are securelyseated on the rail after installation.Starting with the coupler/controller, the I/O modules are mounted adjacent to eachother according to the project design. Errors in the design of the node in terms ofthe potential groups (connection via the power contacts) are recognized, as the I/Omodules with power contacts (male contacts) cannot be linked to I/O moduleswith fewer power contacts.Pos : 73.2 /Serie 750 (WAGO-I/O-SYST EM)/Wic htige Erläuterungen/Sicherheits- und sonstig e Hinweis e/Vorsic ht/Vorsicht: Verl etz ungsgefahr durc h s charfkantige M ess er kontakte! @ 6\mod_1256193279401_21.doc x @ 43414 @ @ 1Risk of injury due to sharp-edged male contacts!The male contacts are sharp-edged.

A ground wirepower contact, which is inserted into a terminal without contacts, e.g. a 4-channeldigital input module, has a decreased air and creepage distance to the neighboringcontact in the example DI4.Pos : 73.4 /Serie 750 (WAGO-I/O-SYST EM)/Wic htige Erläuterungen/Sicherheits- und sonstig e Hinweis e/Achtung/Achtung: Aneinanderrei hen von Bus kl emmen nur bei offener Nut! @ 6\mod_1256193351448_21.doc x @ 43417 @ @ 1Assemble the I/O modules in rows only if the grooves are open!Please take into consideration that some I/O modules have no or only a few powerjumper contacts. The design of some modules does not allow them to bephysically assembled in rows, as the grooves for the male contacts are closed atthe top.Pos : 73.5 /Serie 750 (WAGO-I/O-SYST EM)/Wic htige Erläuterungen/Sicherheits- und sonstig e Hinweis e/Hinweis/Hi nweis: Busabsc hluss nicht vergess en! @ 6\mod_1256194225557_21.doc x @ 43432 @ @ 1Don't forget the end module!Always plug an end module 750-600 onto the end of the fieldbus node!
