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 "S" (Ø = 35 mm), the minimum
inside diameter of the winding roller must be 40 mm;
– 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 of up to 35 Nm, the minimum inside diameter of
the winding roller must be 60 mm;
– for motors that are size "L" (Ø = 58 mm), the minimum
inside diameter of the winding roller must be 70 mm.
3.2 - Assembly and installation of the
tubular motor
Warning! • Before starting, carefully read the warnings un-
der sections 1.1, 1.2 and 1.3. • 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 / 7-b1) and the motor fas-
tening bracket (fig. 7-h).
l For model E MH / E LH: the handgrip of the man-
ual operation mechanism must be positioned no higher
than 1.8 m.

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.
4.3 - Connecting the motor to a control
pushbutton panel and the electrical
mains
Attention!
l Incorrect connection can cause faults or dangerous sit-
uations, therefore scrupulously respect the instructions
given in this paragraph. If in doubt, do not try to experi-
ment but consult the relevant technical specifications
which are also available on the web site www.nicefo-
ryou.com.
l The unit's power cable may not be replaced. If the cable
is damaged, the device must be scrapped.
In electrical terms, the motor must be powered permanent-
ly, via a permanent connection electrical ma ins (consult da-
ta on the rating plate for motor). To connect the motor to a
control pushbutton panel and electrical mains, refer to fig.
5. The connection cable wires are connected as follows:
Cable Connection
Brown Electric ascent or descent phase.
Black Electric ascent or descent phase.
Blue Common (normally connected to the Neutral).
Yellow- Ground (protective electrical bonding). Cable
green not present on series "E S" motors.
4.4 - Associating the Up and Down
movements with the respective
pushbuttons
On completion of connections, power up the motor and
check whether the Up and Down movements are associ-
ated correctly with the relative control pushbuttons. If this
is not the case, invert the connection between the Brown
and Black wires.
