GOT-2770S User’s Manual
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.
2.2.3 CE Requirements
To make an GOT-2770S comply with EMC directives, and to reduce
susceptibility to electrical interference, a separate #14 AWG ground
wire should be taken to the chassis ground terminal of the power
connector. This ground connection should be run directly to the central
star earth connection point (as recommended in most Installation
Instructions).
