For the field power supply, the power requirement must be determined individually for
each feed-in point. All loads through field devices and I/O modules must be taken into ac-
count. The field supply also impacts the I/O modules, since the input and output drivers of
some I/O modules require the voltage of the field supply.
The system supply and field supply must be isolated to ensure bus operation in the event
of short circuits on the actuator side.
Suitable power supplies, e.g., from the EPSITRON product range, can be found in the
eShop.
5.2.5 Mounting Position
All specifications and handling steps refer to the nominal mounting position. Deviating
mounting positions affect, for example:
• Air circulation
• Measuring accuracy
Maintain the following clearances to adjacent components, cable ducts and the sides of
housings and frames for the entire node structure.

Coordinate Model
Note
Modified coordinate model
In product manuals published before 2021, the height (y) and
depth (z) are swapped!
• Width = dimension along x axis = horizontal in nominal mounting position; parallel to
DIN-rail longitudinal axis
• Height = dimension along z axis = vertical in nominal mounting position
• Depth = dimension along y axis = horizontal in nominal mounting position; perpendicu-
lar to DIN-rail longitudinal axis
