GS6 series display to an earth-ground
electrode, follow these steps:
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 rear 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.
