2.6 GROUNDING
Installations are expected to have access to an independent, high quality, noise-free point of earth
reference. The system should be connected by a dedicated, low resistance (less than one ohm)
lead wire directly to the installation’s point of earth reference. This ground reference is referred to
as the Instrumentation Ground. If an instrumentation ground reference does not exist in the installa-
tion, an earth ground electrode should be established with an independent grounding rod or ground-
grid mesh.
