GT6x display
to an earth-ground electrode.
1� Install an earth-ground
electrode (ground rod, ground
plate, etc.) near the base of the
display. Refer to Figure 11 for
guidelines.
Note: Each display face
requires an earth-
ground electrode.
2� Connect a copper wire from
the grounding electrode to the
ground lug on the back of the
display.
3� Bury any copper cable or grounding electrodes so they are below grade.
Important Points About Grounding
• All components of a display system—including but not limited to displays, control
equipment, and connected peripheral equipment—must be electrically grounded.
Only qualified individuals may perform electrical work, including verification of
ground resistance. Daktronics is not responsible for improper grounding or damage
incurred as a result of improper grounding.
• Grounding methods must meet the provisions of all applicable local and national
codes. Inspect and verify all grounding methods meet the provisions of all applicable
local and national codes.
• Proper grounding is necessary for reliable equipment operation and general
electrical safety. Failure to properly ground the display system may void the warranty,
disrupt operation, damage equipment, and cause bodily harm or death.
