The two fixing shafts of the display module are
mechanically designed for a 2 space unit expansion
module.
If you wish to fit wider expansion units, the top-hat rail
must be supported at a third support point.
This third support point should be located in the area
216 mm from the end of the device. It should not be
possible to twist the top-hat rail.
Caution!
The fixing shafts of the display/operating unit are designed
for mounting the expansion units. Other devices such as
contactors must not be mounted on this top-hat rail.
