[. . . ] 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. Make sure that people who install, maintain or operate the gate drive follow these instructions. [. . . ] 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). If the drive gets too hot, it switches itself off until it has cooled down to activation temperature. The outdoor temperature and the gate itself are key factors determining the drive's actual duty cycle · Safety: A sliding gate drive has to be fitted with a flashing lamp, contact strips and, if necessary, with additional light barriers as safety features. Please ensure that you comply with the standards and regulations relevant to your particular case. Control unit: The control unit was developed specifically with safety aspects in mind. The base plate for the drive can either be concreted in or, if appropriate, welded into position. The place where the base plate is usually located is shown on the installation overview. Please note: If it is impossible to precisely determine the height of the plinth and the distance from the gate prior to installation, it is advisable to mount the rack bars first and then concrete in the base plate. The distance from the bottom edge of the rack bar to the base plate is approx. The base plate permits final height and depth adjustments of several centimetres to be made, but you are advised to work as precisely as possible from the outset. Position the drive via the adjustment holes such that its location vis-à-vis the rack bar complies with the installation dimensions. MOUNTING RACK BAR 4 The easiest way to fit the rack bar is to first place it on the motor's drive cog, disengage the motor and, by pushing the gate further with the rack bar, screwing the bar bit by bit firmly in position. In this way, you ensure that the rail bar engages with the cog wheel in an optimum manner. DRIVE RELEASE MECHANISM (MANUAL OPERATION) 5 The drive is equipped with a lockable release mechanism to enable the gate to be operated manually in a power cut. 5 with the clutch disengaging the link between the cog wheel and the gear. To release the drive: Position the socket spanner appropriately and turn it 180 degrees. 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. [. . . ] 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. A sliding gate can also be secured by implementing on-site measures (fence, wall, etc. [. . . ]
