4.1 - INSTALLATION

The motor reducer installation involves a groundwork operation for the canalization of the electrical cables, and, if necessary, the setting of the
base plate. The motor-reducer can be fixed in one of two ways: with pressure-screwed fixed stirrups, by cementing the base plate (as indicated in
fig. 7), or welding the base plate to a metal plate anchored to cement (fig. 8).
In picture 9 you can see the positioning levels of the plate supporting the motor-reducer.
IMPORTANT
For the success of the automation it is necessary for the grounding-work to be done workmanlike, being careful to the measures indica-
ted in picture 9.
For the setting of the plate it is necessary to remind the following indications:
- beware the opening direction of the gate (see picture 10);
- the base plate must be perfectly aligned and, for the cement fixing, cleared from cement wastes and trimmings;
- the base plate must be perfectly aligned with the gate and at the right distance, as indicated in picture 9.

4.2 - MOTOR-REDUCER ASSEMBLY ON THE BASE PLATE

Fix the motor-reducer to the base plate as indicated in picture 11, being very careful not to damage the electrical wires.
WARNING
We suggest to use zinc-coated screws in order to avoid the sticking of the screws caused by rust formation.
While fixing the motor-reducer to the base plate, set it at the working distance as indicated in picture 12.
Keeping that distance from the gate, you have to maintain the perpendicularity between the gate and the motor-reducer, as indicated in picture
13, so that the gear can work perpendicularly to the rack, preventing their wear because of a wrong installation

4.3 - RACK ASSEMBLY

A good rack assembly is necessary for a good functioning of the automation, because it reduces its noise and, above all, it reduces the wear
during the years.
WARNING
You MUST use a 22 x 22 mm rack, which is to be placed in the middle of the motor-reducer pinion and welded to the gate.
It is extremely important for the various parts of the rack to be perfectly aligned, both in height and for the cog pitch. To make this operation
easy we indicate in picture 14 a system which assures the linearity and the pitch between the racks.
If the lower profile of the gate is too low to set up the rack, you have to create a support; picture 15 shows how you can create a
solid base for the rack.
To make sure the weight of the gate does not damage the motor-reducer pinion, the rack must be raised approximately 1 mm above the rest on
the pinion.
Now we are going to explain how you can fix the rack to the gate:
• Open the gate completely and stop the motor-reducer pinion switching off the manual gating.
• Rest the end of the rack on the motor-reducer pinion, and bring it forwards a couple of teeth (as shown in fig. 16). Raise it approximately
1 mm and weld a spot to attach it to the gate.
• Loosen the motor-reducer pinion, and manually move the gate approximately 50 mm. Use a spirit level to make sure the rack is properly ali-
gned, then weld another spot.
• Go on fixing the other parts of the rack as indicated in picture l4, that is: set another rack part close to the already fixed rack part, keeping
them together by a chuck, in a way that one part of the rack tied by the chuck is in close contact with the fixed one, and the other part is free
so that you can lay on it the part of the rack that has to be fixed to the gate; lean the rack you have to fix, always check the alignement with
the level, and fix the rack by a spot welding.
• Follow the instructions as described above for all the rack parts you require. Once you have finished attaching all other parts, open and close
the gate by hand. Make absolutely certain that the minimum effort is required to perform this operation, then weld the rack on for good.
WARNING
Never solder the rack parts to the spacers or between them, and never apply the welder mass to the motor-reducer.

4.4 - ELECTRICAL CONNECTION

Connect electrical flexes as described in the specific instructions enclosed and in accordance with the instructions given in the instructions for
each single apparatus to be connected to the appliance.
WARNING
During the electrical cables connection make sure that they are not connected to the power grid.
The connection must be protected by a differential automatic switch.
The electromechanical brake must have a 230 V supply, using a rectifier (depending upon model chosen).
The connection must be done according to the now-in-force rules and by a qualified staff.
