BECAUSE AC POWER IS BEING RUN INTO THE CONTROL
BOX FOR CONVERSION TO DC, THE GATE OPERATOR
SYSTEM SHOULD BE GROUNDED THROUGH THE EARTH
GROUND IN THE AC MAINS WIRING SYSTEM (GREEN WIRE).
’ This ground connection will prevent dangerous currents in the
control box parts, the actuator, or the gate itself.
’ Nice recommends an 8 foot copper rod driven all the way into
the ground with a copper clamp and 12ga copper wire minimum.
’ Connect ground wire to the grounding lug in the lower left corner
of chassis interior (right).
