sensors are designed for installation in
standard electrical boxes. However, some of the installa-
tion methods vary slightly from traditional methods. If you 
do not understand these instructions or are unsure of your 
abilities, seek the assistance of a qualified electrician.
WARNING
To prevent severe shock or electrocution, 
always disconnect power at the service 
panel before beginning work.
3-Way
In a 3-Way circuit, Traveler wires 
are the two insulated wires con-
nected to the switch that are NOT 
the HOT wire that you identified 
previously.
Single Pole
When replacing existing switches, label 
wires before disconnecting. 
Disconnect old switch.
Briefly restore power and use a line voltage 
meter to identify the wires. 
HOT or LINE (usually black) - runs from 
service panel to switch
LOAD Runs from switch to fixture
NEUTRAL (usually white) The old switch 
may not have used a NEUTRAL wire, but 
it is usually available in the box.
GROUND - bare copper or Green wire 
with or without yellow stripe
DISCONNECT power at the service panel 
once you’ve identified the wires. 
2
If necessary, cut wires and strip 
insulation using stripping guide on 
back of switch.
3
Connect frame ground wire and sen-
sor ground wire to bare ground wire in 
box. Fold ground wires into back of box. 
Mount frame to wall box with screws 
provided. Tighten screws just enough to 
hold frame in place. 
Do NOT over-tighten.
TIPS
• Pre-fold wires into wall box to make it easier to fit them in the 
 box when sensor is connected. 
• Use caution to avoid marring wall surface with the metal frame.
Use only with Legrand adorne
