set limits, automatically shuts off the power supply and
only restores operation when the temperature returns
within the normal range.
- 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.
- 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
specific dimensions and weight. Therefore, be fore pro-
ceeding 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.
- Check the internal diameter of the roller shutter, taking
into account that for the E S motor the minimum internal
roller shutter diameter must be 40 mm, while for E M, E
MH, E LH motors the minimum internal roller shutter di-
ameter must be 52 mm.
3.2 - Tubular motor installation
To install the product, follow the phases shown in fig. 7
and observe the following warnings:
- Incorrect installation can lead to serious injury.
- For model E MH / E LH: the handgrip of the manual
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 catego-
ry 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 safety devices in the electrical
mains
Recommendations:
• Position the push button control panel in view of the
winding device but away from its moving parts.
• 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.
• Position the buttons at a height over 1.5 m from the floor.
4.3 - Connecting the motor to a control push-
button panel and the electrical mains
Attention!
• 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.niceforyou.
com.
• 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 to the 230V electrical ma-
ins. To connect the motor to a control pushbutton panel
and electrical mains, refer to fig. 5. The connection cable
wires are connected as follows:
– Brown = electric ascent or descent phase.
– Black = electric ascent or descent phase.
– Blue = Common (normally connected to the Neutral).
– Yellow-Green = Ground (protective
electrical bonding). Cable not present on series "E S"
motors.
4.4 - Associating the Up and Down move-
ments 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.
