[. . . ] Keep these instructions in a safe place so that you can refer to them quickly when you need to. The full protection against potential squeeze or entrappment must work direct when the drive arms are installed. The sliding gate drive can be activated via push-buttons, key-operated switches, keyless switches (radio) or remote control; once the drive has been disengaged with the appropriate key, the gate can be opened by hand. [. . . ] There are many factors that are key to the choice of the right sliding gate drive. Assuming the gate is in good working order, the most difficult aspect is getting the gate to move. Once the gate is in motion, force requirements are in the main significantly reduced. A light yet long gate (long = + 5m) needs a far greater force to set it in motion than a short, heavy gate does. Gate weight: Gate weight is only an approximate indicator the actual relevance of which can vary greatly. Example: A light gate that slides poorly is likely to need a stronger drive than a heavy, smooth-sliding gate. Caution: A sliding gate must run in a guide rail and should not be able to leave the rail. Temperature: Low outdoor temperatures make it difficult or, in some cases, impossible to get the gate moving due, for instance, to changes in the ground conditions. Operating frequency / Duty cycle: Sliding gate drives have a maximum duty cycle of approx. CHECK LIST - PRE-INSTALLATION WORK Prior to actual installation, please check that you have been provided with all the parts indicated within the scope of supply. The gate must run smoothly, not jerkily and not make contact with the ground at any point. Bear in mind that the ground can be several centimetres higher in winter. The gate needs to be stable with as little play as possible to prevent any lateral movement from occurring. The easier the gate moves, the more sensitive the force setting needs to be. Make a note of the materials you still need and make sure you obtain them prior to installation - adhesive anchors (strong plugs), screws, stops, cable, distributor boxes, tools, etc. 1 OVERVIEW OF INSTALLATION The drive has to be installed behind the wall to ensure that no part of it projects out into the gate opening. Decide which is the best height for fixing the rack bar to the gate and use this to determine the installation dimensions for the motor unit and base plate. Should the gate be unsuitable for fitting the rack bar to it, a fixing profile (angle bracket, shaped tubing, etc. [. . . ] Fit the limit switches on to the rack bar in those places where the final travel positions are roughly expected to be. Screw the retaining clip only provisionally in place or slot it lightly on to the rack bar. Electrical operation is only possible with the control unit that is supplied as standard. [. . . ]
