Refer to figure 6 for the wiring of Nexus models.
These units can accept an input voltage of 120 or 347 VAC:
120 VAC —
Connect the black (120 VAC) lead and white (neutral) lead
to the building utility. Insulate the red wire.
347 VAC —
Connect the red (347 VAC) lead and white (neutral) lead to
the building utility. Insulate the black wire.
Feed excess wire into the junction box.
Leave as much space as possible between the live voltage cabling and
the unsheathed low voltage data cabling.
Run the double insulation of data cables past the line cabling section and
only strip back the last 30mm of the data cable sheathing.
Automatic Diagnostics (Self-Powered Models)
