Additional Information
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.
 Mounting NX Units to Each Other
Use the following procedure to mount NX Units to each other.
1
From the front of the previously mounted NX Unit, engage the Unit hookup guides on a new Unit
with the Unit hookup guides on the previously mounted NX Unit.

When you mount the NX Unit, it is not necessary to release the DIN track mounting hook on the
NX Unit.
After you mount the NX Unit, make sure that it is locked to the DIN Track.
