(AC or solar and battery) and locking-out the power via the operator
power switch. Upon completion of maintenance the area MUST be
cleared and secured, at that time the unit may be returned to service.

EARTH GROUND ROD

Use the proper earth ground rod for your local area. The ground wire
must be a single, whole piece of wire. Never splice two wires for the
ground wire. If you should cut the ground wire too short, break it, or
destroy its integrity, replace it with a single wire length.
1. Install the earth ground rod within 3 feet of the control box.
2. Run wire from the earth ground rod to the control box. The earth
ground wire will be connected in a later step.
NOTE: If the operator is not grounded properly the range of the remote
controls will be reduced.
