DANGER
Do not work on products while energized!
High voltage can cause electric shock or burns!
• Disconnect all power sources from the product before performing any installation,
repair or maintenance.
Note
Note planning documents!
The structure of the node and installation in the system may only be carried out in accor-
dance with the planning documents provided by the system planner.
The following information must be provided:
• Information about the correct node structure
• Information about permissible mechanical, electrical and climatic ambient conditions
• Circuit diagrams
• Mounting position, cable types and lengths

7.1 Assembly Sequence

Head stations and I/O modules from the WAGO I/O System 750 XTR are snapped
directly onto a DIN-rail (EN 60715 (TS 35)).
A groove and spring system ensure secure positioning and reliable connection. An auto-
matic locking mechanism ensures secure mounting on the DIN-rail.
Starting with the head station, the I/O modules are assembled in sequence according to
the project planning. This approach makes errors in the configuration of the node involv-
ing potential groups (connections via the power jumper contacts evident, since I/O mod-
ules with power jumper contacts (blade contacts cannot be connected in a sequence
with I/O modules that have fewer power jumper contacts.
Note the following:
• Only insert I/O modules in the intended order: All I/O modules feature grooves for
power jumper contacts on the right side. For some I/O modules, the grooves are
closed on the top. Therefore, I/O modules featuring a power jumper contact on the left
side cannot be snapped on from the top. This mechanical coding helps to avoid config-
uration errors that could destroy the components.
Therefore, insert I/O modules only from the right and from the top.
• Start XTR sections exclusively with XTR power supply modules: The power
jumper contacts of XTR products use a different contact material than WAGO I/O Sys-
tem 750/753 products. Connecting power jumper contacts of XTR components to
power jumper contacts of non-XTR components leads to irreversible deterioration in
contact characteristics in the long run. Therefore, only start sections of XTR modules
with an XTR power supply module. Only connect XTR modules after XTR power sup-
ply modules, never other modules.
