Grounding
To prevent damage to your installation it is important that all devices are
properly grounded.
Use a grounding wire to ground the KM0032 / KM0532 / KM0932 by
connecting one end of the wire to the switch’s grounding terminal (see page 9),
and the other end of the wire to a suitable grounded object.
