er than those specified in this manual. Operations other
than as specified can only cause malfunctions. The man-
ufacturer declines all liability for damage caused by ma-
keshift modifications to the product.
l The power supply cable of the motor is made of rubber
and is suitable for use in indoor and outdoor environments.
Nevertheless, we recommend protecting the cable along
its entire length by inserting it an appropriate cable tray.
l Do not use multiple control devices for a single tubular
motor or a single control device for multiple tubular mo tors
(fig. 3). If necessary, use the special Nice accessory "TTE".
l During system set-up, keep all persons far from the
shutter when moving.
l To control the product, use exclusively hold-to-run type
pushbuttons, i.e. which must remain pressed for the en-
tire manoeuvre.

PRODUCT DESCRIPTION AND
INTENDED USE
This product is a tubular motor designed for the automa-
tion of a shutter, sun awning or solar screen. Any other
use is strictly prohibited! The manufacturer declines
all liability for damage resulting from improper use
of the product and other than as specified in this
manual.
The product has the following features:
l powered via the electrical mains (consult data on the
motor dataplate);
l designed to move the shutter in Ascent and Descent
by means of wall-mounted pushbuttons (not supplied in
pack);
l is equipped with an electromechanical system that auto-
matically shuts off power supply when the shutter reaches
the set limit positions (fig. 4): position "0" (shutter totally re-
tracted) and position "1" (shutter totally extended);
l install inside the winding roller; the part of the motor that
protrudes from the roller (head) is fixed to the ceiling or the
wall with suitable support brackets (not supplied in pack);
l it is designed for residential use, i.e. discontinuous. It
guarantees a continuous operating time of maximum 4
minutes;
l it is fitted with a thermal cut-out which in the event of
overheating due to use of the automation in excess of the
set limits, automatically shuts off the power supply and on-
ly restores operation when the temperature returns within
the normal range.
l during the installation and adjustment operations, the
motor can be controlled by the "TTU" unit (fig. 6) until the
final electrical connections have been made.

PRODUCT INSTALLATION

3.1 - Preliminary checks – Application
limits
Caution! – Before proceeding with installation, verify
the following.
l There are various versions of this product available, each
designed to manage a specific motor torque. Each is de-
signed to automate shutters / awnings / scre ens with spe-
cific dimensions and weight. Therefore, be fore proceeding
with installation, refer to the "Guide to selection" in the Nice
product catalogue (www.nice for you .com) to check that the
characteristics of this motor (motor tor que, rotation speed
and operating time) are suitable for automating your shutter
/ awning / screen. Caution! - Never install a motor with
a greater motor torque than that required to move
your shutter / awning / screen.
l Check the diameter of the winding roller. This must be
chosen according to the motor torque, as follows:
– for motors that are size "M" (Ø = 45 mm) and have a
torque of up to 35 Nm (included), the minimum inside
diameter of the winding roller must be 52 mm;
– for motors that are size "M" (Ø = 45 mm) and have a
torque greater than 35 Nm, the minimum inside diam-
eter of the winding roller must be 60 mm.
3.2 - Assembly and installation of the
tubular motor
Warning! • Before starting, carefully read the warnings
under sections 1.1 and 1.2. • Incorrect installation could
cause severe physical injury.
To assemble and install the motor, refer to fig. 7. Moreover,
consult the Nice product catalogue or go to www.nicefo-
ryou.com to choose the crown of the limit switch (fig. 7-a
/ 7-a1), the drag wheel (fig. 7-b) and the motor fastening
bracket (fig. 7-h).

ELECTRICAL CONNECTIONS

4.1 - Installing safety devices in the
electrical mains
In compliance with the electric installation rules, in the net-
work that powers the motor, a short circuit protection de-
vice and a disconnection device from the mains electricity
must be envisioned.
Attention! – The disconnection device must allow
the complete disconnection of the power supply, in
the conditions established by the over-voltage cat-
egory III.
The disconnection device must be located in view of the
automation and, if it is not visible, must envision a system
that blocks any accidental or unauthorised re-connection
of the power supply, in order to prevent any danger.
Note – The two devices are not present in the package.
4.2 - Installing the wall-mounted push-
button control panel
Recommendations:
l Position the push button control panel in view of the
winding device but away from its moving parts.
l Position the push button control panel on the side of the
winding device, where there is the electric cable coming
from the tubular motor and the mains electricity power
supply cable.
l Position the buttons at a height over 1.5 m from the
floor.
