Grounding
The optimum method for grounding electronic equipment is to
ground it separately from other high-power systems and to ground
more than one unit of electronic equipment with a single-point
ground. The Grounding marked terminal (see below) is provided on
the unit.
[Note: Do not use a ground that has an unstable impedance, such as
painted screws or a ground subject to vibration.]
