Orientation is possible in the following six directions.
(A) is the upright orientation and (B) to (F) are other orientations.
However, there are restrictions on the installation orientation and restrictions to specifications that can
result from the Communications Coupler Units and NX Units that are used.
Refer to the user's manuals for the Communications Coupler Units, NX Units and System Units that you
will use for details on restrictions.
Precautions for Safe Use
For installation orientations (C) and (D) in the above figure, support the cables, e.g., with a duct,
so that the End Plate on the bottom is not subjected to the weight of the cables. The weight of
the cables may cause the bottom End Plate to slide downward so that the Slave Terminal is no
longer secured to the DIN Track, which may cause malfunctions.
