Conduit
In order to protect the wires, use PVC conduit for control wires, conduit must be set into the
concrete when it is poured. Wires within the conduit shall be located or protected so that no
damage can result from contact with any rough or sharp part.
Concrete pad
The base unit of the gate operator requires a concrete pad in order to maintain proper stability.
The concrete pad should be approximately 300mm x 200mm x 200mm deep in order to provide
for adequate operation.
Anchors
You can use the anchors, bolts, washers and nuts that are provided with the operator. These
anchors must be set into the concrete when it is poured, or you can use wedge anchors.
Operator
In locations where ground freeze is possible, mount the gate operator on installation pad as
shown in Fig.2. Check the operator and make sure it is lined up with the gate.

Installation of rack (see Fig.3)
Fix the three nuts (in the same package with rack) on the rack element.
Lay the first piece of rack on the gear and weld the first nut on the gate.
Move the gate manually, checking if the rack is resting on the gear, and weld the second
and third nut.
Bring another rack element near to the previous one. Move the gate manually and weld the
three nuts as the first rack, thus proceeding until the gate is fully covered.
When the rack has been installed, to ensure it meshes correctly with the gear.
The space between rack and gear is about 1mm.
﹡ If you have installed an external
button switch, you must use two
conduits: one for main power wire,
another one for low voltage wire
(button switch).
