Laying the foundation plate - Cement foundation
If there is no cement flooring (or similar material) a cement* foundation must be pre-
pared. Proceed as follows:
1 - Dig a suitable hole (minimum 40x30cm, at last 35cm deep), considering the meas-
urements indicated in the previous paragraph.
2 - Prepare the pipes for the passage of the electric cables (see “Electric connections”),
leaving the pipes longer by about 30/40cm (figure 4-ref.T).
3 - Bend the 4 threaded bars:
a) if the rack is pre-installed at a measurement greater than that indicated in Figure 1,
or in the case of possible water stagnation, the foundation plate may have to be raised.
In this case, bend the bars at a height of about 45 mm as indicated in Figure 5.
b) if the motor will be fixed to the ground, bend the bars at a height of about 30 mm
as indicated in Figure 6.
4 - Prepare the plate for the cast, fixing the threaded bars. With reference to Figure 7
use 4 lower support nuts D and 4 nuts F with the relative washers R to block the plate
in position. The position of the bars must be similar to that indicated in figure 7.
5 - Prepare the cement following the manufacturer’s indications. In some cases it may
be necessary to realise a metal cage to make the foundation more stable.
6 - Sink the bars into the cement, paying attention to the level of the plate and the
parallelism with the leaf (figure 8).
7 - Wait for the cement cast to be reinforced.
8 - Remove the upper screws and washers, which will be successively used to fix the
gear motor.
9 - Figure 9 shows the plate when fixing is ultimated. If necessary, it is now possible
to raise the plate by a maximum of 20 mm, positioning 4 nuts and the relative washers
under the plate, as indicated in figure 10.
* If in doubt, contact qualified staff for realisation of the foundation.
The plate must be tightly fixed to the ground, perfectly levelled and pa-
rallel to the leaf.

It is also indispensable that the rack projects, with respect to the centre of the plate, by
at least the measurements indicated in figure 3a (motor on left) and 3b (motor on right)
to allow positioning of the end run brackets.
In some cases it is possible that the rack projects by a few centimetres
with respect to the plumb line of the gate in order to allow complete
closure.
Make note of the measurements indicated before proceeding with the successive
phases.
The foundation plate has two large holes for the passage of the raceways.
They can both be used, thanks to the space present on the bottom of
the gear motor, but it is easier to use the hole of the left if the pinion,
highlighted in the figures.
