Image 4 – Single switch situation
Note the following in the above situation:
• Only one of the two black switching wires on the EM6557 is used
• The remaining black switching wire needs to be covered using a terminal block or
wire nut
• The cable between the wire nut and the wall switch is coloured black in the
drawing, but can also be brown in a real situation. If you have/use a brown cable,
make sure this is not a live wire anymore
• The brown live wire between the wall switch and junction box is now used to
connect the white switching cable. Therefore the cable needs to be coloured
black or white (using adhesive tape for example)
• The brown wire can only be used in this situation if it is coming from the ceiling
junction box. You need to check first where the brown wire is coming from before
connecting it to the EM6557
• If the brown wire is connected to a wall switch with wall outlet you need to run an
extra wire
