5. Setup and Installation
Follow these steps for proper installation of your FMLWL LED Wraparound Light Fixture. Ensure power is disconnected at the circuit breaker before starting.
- Prepare the Fixture: Carefully remove the diffuser from the housing. Then, remove the wireway cover by unscrewing the two screws securing it to the fixture housing.
- Access Wiring: Locate the black supply wire, the white neutral wire, and the green grounding wire inside the fixture. Push all three wires out through the coined hole at the back of the fixture.
- Connect Ground Wire: Hold the fixture housing firmly. Connect the green ground wire from the fixture to the bare copper ground wire from the junction box using a wire nut.
- Connect Supply Wires: Use wire nuts to connect the black fixture wire to the black supply wire and the white (neutral) fixture wire to the white supply wire.
- Mount the Fixture: Align the keyholes on the back of the fixture housing with the screws previously installed in the junction box. Lift the fixture up, rotate it clockwise, and tighten the screws to secure the housing assembly against the ceiling.
- Reinstall Diffuser: Starting at one end of the housing, insert the diffuser slot onto the edge of the housing. Carefully squeeze the diffuser to engage the opposite side with the housing until fully installed.
- Select CCT and Lumen Output (if applicable): Use the integral switches on the fixture to select your desired LED Correlated Color Temperature (CCT) and lumen output.
