NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)
Always turn OFF the Unit power supply and I/O power supply before you remove the NX Unit.
1 Use a flat-blade screwdriver to pull up the DIN Track mounting hook on the Unit to remove.
2 Put your fingers on the protrusions for removing multiple NX Units including the Unit to be
removed, then pull out straight forward to remove.
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.
• When you remove a Unit, be careful not to touch or bump the pins in the NX bus connector.
