2.2.2 Grounding
Requirements
Chassis ground must be used. DC ground is not directly coupled to Earth
ground internally. It is preferable not to ground DC negative return to
chassis ground as poor site earths can introduce noise into a system, but if
necessary an earth connection should be made, from the power supply
return point to the central star earth point. Ground conductors should be as
short and as large in size as possible. The conductors must always be
large enough to carry the maximum short circuit current of the path being
considered. Ground conductors should be connected to a tree from a
central star earth ground point. This ensures that no ground conductor
carries current from any other branch.
