Press the NX Unit with a certain amount of force against the DIN Track until you hear the DIN
Track mounting hook lock into place.
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.
Additional Information
• Normally, it is not necessary to release 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 a recommended DIN
Track, the DIN track mounting hook may not lock correctly. If that happens, first unlock the
DIN track mounting hook, mount the NX Unit to the DIN Track, then lock the DIN track mount-
ing hook.
• Refer to the user's manual of the Communications Coupler Unit for information on how to
mount the Communications Coupler Unit, and how to mount the NX Unit to the Communica-
tions Coupler Unit.
