To prevent accidental electrical shock or damage to your switch, it is
recommended that you ground the switch to an earth point by attaching a
grounding wire (not supplied) to the grounding point located next to the power
inlet, with a metal screw. If located in a tall building, grounding points include
metal drain pipes, and other electrostatic conductive devices that lead to the
ground, or if located on the first floor of a building, the ground outside itself.
