These motors are fitted below ground level with the operator drive shaft aligned with the axis of the gate hinge. In order to attain this alignment the hinge centre must be clear of the face of the gate post.

The operator will support an 800 kg load and it is recommended that it replaces the lower hinge of the gate (i.e. not installed below a pair of existing hinges) The operator runs on a timed sequence set at the system control panel or you can use loop detectors to sense when the car have passed throught. Gate stops are required in some cases. Requiered would be the open and closed position of the gate to stop the gate before the operator reaches the end of its travel.
