- Black – represents the line input, 120VAC
- White – represents the neutral. The LFM-20 and the load must share the same neutral.
- Blue 1 (either blue wire) – 24V – 277V input for load switching
- Blue 2 (either blue wire) – 24V – 277V output for load switching
The switch also has a green wire which serves as the ground. While there is a yellow wire present, it is not needed and should be cut and capped with either electrical tape or a wire nut.
In the case of a 3-way or 4-way circuit, traveler wires are not used when building an Evolve network. Instead, an LFM-20 may be used in conjunction with an LTM-5 to create a wireless, “virtual” 3-way. See LTM-5 for further details.
