Mounting
The I/O station can be mounted horizontally, vertically or in combinations
(Figure 53 to Figure 57). Compact or Extended MTUs or S800L modules can be
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
2/3 wire termination and power distribution arrangements). Compact and Extended
MTUs as well as S800L modules can be mixed and matched within the I/O station
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,
ModuleBus Modem, MTUs and S800L I/O modules are mounted on the DIN-rail.
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.
