LEGRAND Wattstopper WS-301 Mode D'emploi page 3

WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
1. Connect the existing wires in the wall box to the sensor flying leads. (See Wiring Directions).
• Do not allow bare wire to show below connector.
• The ground wire must be tightly grounded for the unit to operate properly.
2. Attach the sensor to the wall by mounting it in the wall box with the two mounting screws provided.
3. Turn ON power at the circuit breaker.
4. Test the sensor using the procedure in the Sensor Adjustments section.
There is an initial warm-up period after installation. It may take up to a minute before the load turns ON due to a sensor
warm-up period during initial power-up (this occurs during installation only). The load turns ON after the warm-up period ends if the
sensor detects motion.
Rapid successive pressing of the ON/OFF button causes a delay in function. A single press of the button causes an
immediate response. If the button is pressed again within 2 seconds, the switch ignores it if there is not enough power. Wait at
least two seconds between button presses.
5. Install industry standard decorator wall switch cover plate (not included).
For normal installation of the WS-301 and WS-301-347, connect:
1. LOAD to Red flying lead.
2. LINE to Black flying lead.
3. GROUND to Green.
