5-3-5 Mounting the End Cover
It is not normally necessary to unlock the DIN Track mounting hook when you mount the NX
Unit. However, if you mount the NX Unit on a DIN Track that is not one of the recommended
DIN Tracks, the DIN Track mounting hook may not lock properly. If that happens, unlock the
DIN Track mounting hook at the start of the procedure, mount the NX Unit to the DIN Track, and
then lock the DIN Track mounting hook.
Always mount the End Cover (NX-END02) provided with the product to the end of the CPU Rack.
The End Cover has a metal portion and is heavier than it looks. Be careful not to drop it when
handling.
Precautions for Correct Use
Always mount an End Cover to the end of the CPU Rack to protect the last Unit on the CPU
Rack. Not mounting the End Cover may result in malfunction or failure of the CPU Unit.
1 From the front of the CPU Unit, slide the End Cover along the Unit hookup guides on the right-
most Unit on the CPU Rack.
2 Press the End Cover firmly against the DIN Track until you hear it lock into place on the DIN
Track.
After you mount the End Cover, make sure that it is securely mounted on the DIN Track.
