Precautions for Correct Use
• When removing an NX Unit, remove multiple Units together which include the one you want
to remove. If you attempt to remove only one Unit, it is stuck and hard to pull out.
• Do not unlock the DIN track mounting hooks on all of the NX Units at the same time. If you
unlock the DIN Track mounting hooks on all of the NX Units at the same time, all of the Units
may come off.
The following explains the installation orientation for each NX Unit connection destination.
Orientation is possible only in the upright installation orientation.
However, there are restrictions on the specifications depending on the NX Units to be used.
Refer to the user's manuals for the NX Units and System Units that you will use for details on restric-
tions.
