standard rail for installation. The DIN rail does not provide adequate support for the twisted
pair extender with vibration greater than 10 g.

Although the captive screw in the lower part between slots 12 and 13 of the extender module
is not used when installing on a 35 mm DIN rail, it is nevertheless advisable to remove the
media modules.
Note
Make sure that in addition to the extender width of 87 mm, there is a clearance of 20 mm to
the right of the basic device on the DIN rail to be able to align the guide bolts of the extender
with the holes in the basic device du
