Installation
End stoppers must be used at the ‘open’ and ‘closed’ positions.
The stopper for the closed position should also prevent that contact strips are squashed if they are
being used.
a) The foundation must be free from frost, and the opener must stand at least 30 mm higher than the
surrounding terrain and at least 100 mm from the gate opening. Decide what cables are required. Make
sure sufficient cable conduit or cable is laid into the foundation. Using the example in section 7.
b) Loosen the four screws and remove the hood.
c) You now have access to all holes for cables and ground fixation.
d) Place the opener with 65 mm distance from the gate with the back parallel to the gate.
e) Mark the middle of the elongated holes on the foundation.
f) Take the opener from the foundation and drill holes for 8 mm diameter plugs or anchor bolts.
g) Lay the 0.5 mm cardboard between the opener and the foundation and secure the opener with the anchor
bolts.
