6. Setup and Installation
Follow these steps for a quick and easy installation:
- Step 1: Turn Off Power. Before starting, ensure the power supply to the installation area is turned off at the circuit breaker.
- Step 2: Secure Base Plate. Unscrew the plastic mounting ring from the new light fixture. Use the provided screws to secure this base plate to the junction box on your ceiling.
- Step 3: Connect Cables. Connect the electrical wires: white to white (neutral), black to black (live), and the green wire (ground) to the junction box ground. Use the supplied wire nuts to secure connections and consider wrapping with electrical tape for added safety.
- Step 4: Push Wire Nuts Upwards. Carefully push the connected wire nuts and excess wiring into the junction box.
- Step 5: Attach Lamp. Align the light fixture with the secured base plate and rotate it clockwise until it locks securely into place. This mechanism is similar to attaching a smoke detector to its mounting ring.
- Step 6: Restore Power. Once the fixture is securely installed, restore power at the circuit breaker.
