Installation Position
Along with horizontal and vertical installation, all other installation positions are
allowed.
Use an end stop in the case of vertical mounting!
In the case of vertical assembly, an end stop has to be mounted as an additional
safeguard against slipping.
WAGO order no. 249-116 End stop for DIN 35 rail, 6 mm wide
WAGO order no. 249-117 End stop for DIN 35 rail, 10 mm wide

Overall Configuration
The maximum total length of a fieldbus node without fieldbus coupler/controller
is 780 mm including end module. The width of the end module is 12 mm. When
assembled, the I/O modules have a maximum length of 768 mm.
Examples:
•
64 I/O modules with a 12 mm width can be connected to a fieldbus
coupler/controller.
•
32 I/O modules with a 24 mm width can be connected to a fieldbus
coupler/controller.
Exception:
The number of connected I/O modules also depends on the type of fieldbus
coupler/controller is used. For example, the maximum number of stackable I/O
modules on one PROFIBUS DP/V1 fieldbus coupler/controller is 63 with no
passive I/O modules and end module.
Observe maximum total length of a fieldbus node!
The maximum total length of a fieldbus node without fieldbus coupler/controller
and without using a 750-628 I/O Module (coupler module for internal data bus
extension) may not exceed 780 mm.
Also note the limitations of individual fieldbus couplers/controllers.
