[. . . ] 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 all-pole disconnection by means of a switch (at least 3mm contact gap) or by a separate fuse. [. . . ] 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. Gate size: Gate size is a very important factor. 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. This means end stops need to be fitted for both directions! 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. CAUTION: The drives were not designed to be run for the maximum duty cycle on a regular basis (permanent operation). 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. Make sure your gate system is in good working order. 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. [. . . ] electrical connections: See control unit instructions. Always ensure that the mechanical and electrical safety requirements relevant to the given system are complied with. Check at regular intervals (monthly) that the gate hardware and the drive are all firmly in place. disengage the drive and check gate functionality. [. . . ]
