Grounding Requirements
Proper grounding is essential for personal safety and to prevent
emission of high-frequency interference. See Grounding Safety in
Section 1 and Appendix A for system grounding requirements.
Connect the worktable to a high-quality earth ground, not more
than 20 feet (6 m) from the table. A suitable ground consists of a
solid copper rod of at least 1/2" (13 mm) diameter driven to a depth
of at least 8 feet (2.5 m) into the earth, below the permanent
moisture level. Ensure that all grounding connections are tight to
avoid excessive heating. Consult national or local electrical codes
for compliance and additional information .
Connect all HD4070 system components to earth ground. Use a minimum of 8 AWG (10mm
2
) wire connected from
each component to the work table ground.
