2.6 Mechanical Setup
2.6.1 Installation Position
Along with horizontal and vertical installation, all other installation positions
are allowed.
Attention
In the case of vertical assembly, an end stop has to be mounted as an addi-
tional safeguard against slipping.
WAGO item 249-116 End stop for DIN 35 rail, 6 mm wide
WAGO item 249-117 End stop for DIN 35 rail, 10 mm wide
2.6.2 Total Expansion
The length of the module assembly (including one end module of 12mm
width) that can be connected to the coupler/controller is 780 mm. When as-
sembled, the I/O modules have a maximum length of 768 mm.
Examples:
• 64 I/O modules of 12 mm width can be connected to one cou-
pler/controller.
• 32 I/O modules of 24 mm width can be connected to one cou-
pler/controller.
Exception:
The number of connected I/O modules also depends on which type of cou-
pler/controller is used. For example, the maximum number of I/O modules
that can be connected to a PROFIBUS coupler/controller is 63 without end
module. The maximum total expansion of a node is calculated as follows:
Warning
The maximum total length of a node without coupler/controller must not ex-
ceed 780 mm. Furthermore, restrictions made on certain types of cou-
plers/controllers must be observed (e.g. for PROFIBUS).
