Step 2: Remove the existing faceplate and light switch, then identify Live/Load, Neutral and Ground lines.
Step 3: Wire up the Smart Switch with the provided wire connectors as follows:

• Brown wire on switch (Load Line) to Load Line, like a bulb

Please wrap electrical tape around the wire nuts to make sure the copper conductor is fully concealed.
