INSTALLATION » STANDARD INSTALLATION + COMPACT INSTALLATION WELD THE OPERATOR ARM Once the operator arm measurements are verified: 1 Weld the gate bracket to the gate. 2 Weld the short arm section. 3 Weld the long arm section. 1 3 NOTE: Completely weld around the outer tubing and bracket. SECURE THE OPERATOR ARM TO THE OUTPUT SHAFT 1 Position the operator arm onto the output shaft so that the pin slides into the slot. 2 Adjust the nuts on the operator arm so the operator arm fits snug on the output shaft yet still allows enough room to swivel (the handle must be in a 90° position). 3 Tighten the handle by pushing it down. Test to make sure the operator arm does not slip on the output shaft. 2 1 Slot Output Shaft Pin 2 3 WIRING » EARTH GROUND ROD EARTH GROUND ROD Proper grounding gives an electrical charge, such as from an electrical static discharge or a near lightning strike, a path from which to dissipate its energy safely into the earth. Without this path, the intense energy generated by lightning could be directed towards the gate operator. Although nothing can absorb the tremendous power of a direct lightning strike, proper grounding can protect the gate operator in most cases. 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. NOTE: If the operator is not grounded properly the range of the remote controls will be reduced. 1 Install the earth ground rod within 3 feet of the operator. 2 Attach the ground wire to the ground terminal on the control board. 14 OVLD AC PWR /SOLAR 2 12 gauge copper wire 1 Check national and local codes for proper depth
