• Fit an omnipolar or magnetothermal switch on the mains power supply,
having a contact opening distance equal to or greater than 3,5 mm.
• Check that a differential switch with a 0.03A threshold is fitted just before
the power supply mains.
• Check that earthing is carried out correctly: connect the automation
system to earth.
• Only use original parts for any maintenance or repair operation.The Com-
pany declines all responsibility with respect to the automation safety and

2) GENERAL OUTLINE
Compact sturdy self-braking tubular gearmotor, available in different versions
depending on the requirements and field of use.
All the models are self-braking and provided with a self-resetting thermal
circuit breaker. End-of-stroke operation can be quickly adjusted by means
of 2 screws.
In case of power disconnection, the manoeuvre can be carried out by means
of an articulated rod.

The activation device for the manual manoeuvre must be positioned at a
height lower than 1,8 m.
If the operator is controlled by a switch that is manually powered, it should
be positioned in a visible place with respect to the apparatus, but anyway
far from movable parts and at a height greater than 1,5 m.
For motors belonging to the LOOP 50 series, the minimum diameter of the
housing pipe is 50 mm.

5) ACTUATOR INSTALLATION

5.1) Preliminary checks

Check that:
• The structure is sufficiently robust (tube thickness 1÷1.2mm). Repair or
replace faulty or worn parts.
• the model chosen is suitable for the size and weight of the roller shutter
to be automated. Fig. 2 shows the maximum weight in kilograms for each
model and each diameter of tube to be fitted.
• the adapters for the tube and the fixing brackets are suitable for the type
of installation to be carried out.Consult the catalogue for accessories and
purchase the necessary parts.
5.2) Calculation of the winding tube length
a) Fit the appropriate support bracket, and check that the roller is parallel
and perpendicular to the shutter panel (fig.3).
b) Calculate the length of the tube, as shown in fig.4. The formula is
where:
B = Winding tube length
L = Total clearance inside the shutter box
A = Distance between the box wall and end-of-stroke towing ring nut (fig.4-
rif."G"). Insert the end-of-stroke towing ring nut and position the square
shaft which secures the actuator to the support bracket fitted; measure
the distance between the inside box wall and the edge of the end-of-
stroke towing ring nut (fig. 4-rif. "G").
C = Distance from the box wall to the winding tube on the side opposite the
actuator.
5.3) Operator assembly
a) Insert a towing ring nut suitable for the existing winding tube (fig.5-ref."G").
b) Insert the pulling wheel (fig.5-ref."C") in the towing shaft and secure it
with the clip (fig.5-ref."F").
