used depending on available space and preferred way of installing the field wiring
(external marshalling/power distribution or direct on Extended MTUs using built in

to suit the required field termination.
The S800 I/O is mounted on a DIN-rail. The DIN-rail is mounted in a cabinet or on
an enclosure wall to a metal sheet with fastening screws every 100 mm to ensure a
good chassis ground connection in the cabinet or on an open track. The FCI,

It is recommended to use end supports when mounting the I/O station. 
In environments with major vibrations, the MTUs shall be screwed on the metal
sheet.
