Precautions for Correct Use
• When you need to remove an NX Unit, always remove more than one NX Unit at a time, in-
cluding the Unit you need to remove. It is sometimes very difficult to remove only one NX Unit
by itself.
• Do not release the DIN Track mounting hooks on all of the NX Units at the same time. If you
release the DIN Track mounting hooks on all of the Units at the same time, all of the Units will
come off.
