[. . . ] Do not allow children to play with pushbuttons or remote controls. A gate can cause serious injuries as it closes. Disconnect electric power to the system before making repairs or removing covers. A disconnecting device must be provided in the permanently-wired installation to guarantee allpole disconnection by means of a switch (at least 3mm contact gap) or by a separate fuse. [. . . ] pOST FIXING BRACKET Choosing the correct location for the post fixing bracket has a decisive impact on the subsequent functioning of the system. It determines the distance between the motor's centre of motion and the gate's centre of motion and hence the opening angle. These dimensions are referred to as dimension A and dimension B. Do not underestimate the effect that these dimensions have on correct functioning and running. Try to achieve the best possible dimension for your opening angle that is suitable for all circumstances. If the post is not wide enough, an extension piece must be fitted to it. If the post is too thick, cut out part of it to make it thinner or offset the gate. To obtain ideal dimensions, it may be necessary to shorten or lengthen the supplied hinge plate. In the case of gates that are to be custom made, if the gate hinges are fitted on the posts appropriately, it is possible to influence dimensions A and B. Before the final mounting dimensions are determined, you should always check whether or not there is any possibility that the corner of the drive mechanism will hit the post as the gate swings. iNSTALLATION: The drive mechanism exerts considerable force against the post. Usually, acceptable mounting dimensions are obtained if the supplied hinge plate is welded directly onto the post. In the case of thick stone or concrete posts, the hinge must be welded to a base plate and attached so that the plugs cannot work loose during operation. Heavy-duty plugs where a threaded rod is bonded into the masonry stress-free are more suitable for this purpose than steel or plastic straddling plugs. In the case of brickwork pillars, bolt a relatively large steel plate that covers several bricks on to it and then weld the hinge plate to it. An angled plate attached over the corner of the post is also a good means of fixing the operators. Make sure your gate equipment operates perfectly. The gate must run evenly and smoothly and must not stick at any point. Remember that the ground level may be several centimeters higher in winter. The gate must be stable and as free of backlash in order to prevent any unwanted movement. The more smoothly the gate wing runs, the more sensitive the force adjustment must be. Write down any materials you still need and obtain them before starting to install. [. . . ] The capacitor can be connected inside the distribution box or in the controller. Always remember to earth the installation. mAINTENANCE WORK The drive mechanism is maintenance free. Check that the gate fittings and the drive mechanism are securely fixed at regular intervals (monthly). [. . . ]
