Legrand OSR300S 120/277VAC - Manual (Page 5)

1. Make sure that the power has been turned off at the circuit breaker.
2. Connect wires to the OSR300S wire leads as shown in the wiring diagrams.
The ground wires must be tightly fastened or the unit will not operate
properly. If the metal junction box is grounded, it can be a suitable ground.
Attach a ground wire to the green terminal as shown.
3. Attach the sensor to the wall box by inserting screws into the two wide holes
on the top and bottom of the attached metal bracket. Match them up with the
holes in the wall box and tighten.
4. Turn the circuit breaker on. Wait one minute, then push the Auto ON/OFF
switch for each load and the lights will turn on. There is a delay due to initial
power-up of the sensor that only occurs during installation.
