Feet for grounding
The metal bottom of the case must be grounded to avoid "isolated capacities"
to be charged. Therefore the two feet of the case close to the cable outlet are
electrically connected with the metal bottom of the case, which must have a
conductive connection with the desktop. The user is responsible for the
sufficient ground connection of the desktop.
