3. Prepare one or more conduits for the electrical cables before pour concrete. Remember that cable
conduits have to pass through the hole on the base.
4. Pour concrete and before it starts to harden, check that it is parallel to the gate leaf and perfectly level.
5. Mark the position of four expansion anchors according to the position of mounting hole on the base plate.
Double check your marking, move the base plate and drill the 4 holes using a 14mm (0.55”) masonry bit. Put
the 4 expansion anchors (provided) into the holes and firmly tighten.
6. Mount the base plate to the concrete Pad and firmly tighten, enabling the opener is firmly secured
on the concrete pad during the whole gate travel.
