4.2 INSTALLATION DIMENSIONS
Procedure for finding the securing position of the operator, using
Fig. 5 to help you:
measure dimension “ A ” of the gate and trace a horizontal line
on the graph on the measured value, this line to cross the whole
graph.
you will obtain the maximum permissible angular opening accor-
ding to dimension “
A
” of the graph.
select the opening range you require
select dimension “ B ” so that it intersects the horizontal line (di-
mension “ A ”) inside the required opening range.
If dimension “A” permits opening values greater than the ope-
ning value selected, the value of dimension “B” can change
up to the maximum permissible opening value.
Make sure that the minimum dimension of 450mm in Fig. 5 is
observed.
When the operator has been installed, check if dimension “X”
in Fig. 5 is minimum 500 mm. If dimension “X” is less than
500 mm, run an impact test on the point indicated in Fig. 5,
as described in UNI EN12445 standard, and make sure that
the measured values conform to the specifications of UNI
EN 12453 standard.
If the thrust values are not within the values specified in UNI
EN12453 standard, the zone indicated in figure 5 MUST be
protected with a protective device conforming to the UNI
EN12978 standard.
The operator was studied and made to be secured vertically
(Fig. 6). The operator cannot be installed in other positions.
4.3. INSTALLING THE OPERATOR
When you have established dimensions “ A ” and “ B ”, you can install
the operator as follows:
Loosen by about 1/2 turn the four securing screws of the up-
per housing (Fig. 7 ref.
/
) and withdraw the housing. Set the
operator for manual operation, see paragraph 6.
Establish the height of the operator, bearing in mind that:
the securing bracket of the curved arm must be in a zone
where it can be secured to the gate leaf (Fig. 8)
the minimum off ground height of the operator must permit
securing the curved arm and positioning the lower housing (at
least 85 mm, see fig. 8).
the lower edge of the rear bracket must be aligned with res-
pect to the upper edge of the front bracket (Fig. 9).
Secure the rear bracket in the position you had established,
using four M8 screws. As you secure the bracket, respect the
lay-out in Fig. 10 and check, using a level, if the bracket is
horizontal.
To improve water tightness, the external housing covers the
securing bracket - this prevents the bracket from being
directly welded on the pilaster.
The rear bracket must be secured on an as smooth as possible
surface. For masonry pilasters, a counter-plate for walling is
available as an accessory.
Position the operator on the bracket you have just secured,
using two M8x100 screws and the relevant nuts - supplied
(Fig. 11).
Set the operator for manual operation, see paragraph 6.
Install the straight arm (Fig. 12) with the supplied screw.
Assemble the rest of the arm as illustrated in Fig. 13.
For correct operation, tighten the two securing screws (Fig.
13 ref.
/
) and then loosen them by about 1/2 turn to enable
rotation without any friction on the arms.
Align the arms you have just assembled, pushing in the central
zone until they stop, see Fig. 14 ref.
/
.
There are two stops on the curved arm to facilitate the ali-
gning operation.
Rest the front bracket on the leaf, Fig. 14 ref.

.
Move back the front bracket by about 20 mm and mark the
securing holes, Fig. 14 ref.

.
Secure the bracket in the established position using two M8
screws.
We advise you to secure the bracket with the screws, and

not weld it to the leaf, in order not to rule out future adjust-
ments.
Move the bracket by hand and - with the leaf in closing position
- make sure that the two arms do not impact each other, as
shown in Fig. 14 ref.

.
Take the operator back to the work position - see paragraph
6.
4.4. WIRING THE OPERATOR
When you have finished securing the operator, you can wire it.
There are three holes in the lower part of the operator. They should
be used for positioning the cable grippers, for routing the power
cables, for connecting accessories and, if necessary, for connecting
the second motor.
Install all the three supplied cable grippers with the securing
nuts (Fig. 15).
Always use the largest cable gripper (Fig. 15 ref.
/
)
If the other two cable grippers are not used, they must be
closed, using the supplied plugs (Fig. 15 ref.
0
). Fit the plastic
plug in the cable routing hole and close the cable gripper
until it is tight.
Connect the power cable, as shown in Fig. 16. The earthing
wire must also be connected. Make sure that the power cable
wires are correctly fitted in the ‘comb’ which restrains them
Fig. 16.
If the protective fuse has to be replaced, use a fuse with the
following characteristics: 5x20 2A 450V.
Wire all the accessories and safety devices, observing the
relevant instructions.
4.5. POSITIONING THE MECHANICAL STOPS
The 391 operator is supplied standard with opening and closing
mechanical stops. This is to facilitate the installation operations
because there is no need to construct the mechanical stop ele-
ments. The mechanical stops should be fitted in the lower part of
the operator, coupled to a toothed sector. Installation procedure
for the stops:
O
PENING MECHANICAL STOP
Set the operator for manual operation, see paragraph 6.
Manually move the leaf to its opening position.
Take the mechanical stop as close as possible to the straight
arm and fasten the two securing screws.
Make sure that the toothed sector is coupled correctly.
C
LOSING MECHANICAL STOP
Use the closing mechanical stop only in the absence of a
mechanical stop on the closing leaf.
The closing mechanical stop does not guarantee locking the
leaf in case of burglary.
Set the operator for manual operation, see paragraph 6.
Manually move the leaf to its closed position.
Take the mechanical stop as close as possible to the straight
arm and fasten the two securing screws.
Make sure that the toothed sector is coupled correctly.
5. AUTOMATED SYSTEM TEST
When you have made all the necessary electrical connections,
power up the system and program the control unit according to
your requirements.
Run the test for the automation and for all the connected acces-
sories, taking great care when checking the safety devices.
Re-locate the upper covering housing, tighten the securing screws
and position the four covering plugs fig. 18 ref.
/
.
Position the lower housing as shown in fig. 18 ref.
0
.
Hand the “User’s Guide” booklet to the customer and describe
its correct operation and use.
Point out, to the end user, any residual risks present in the
installation.
