ELECTRICAL CONNECTIONS
WARNINGS!
• The operations described in this chapter must be car-
ried out exclusively by a qualified electrician, in accord-
ance with these instructions and with the local safety
regulations in force.
• Incorrect connections can cause faults or hazardous
situations; therefore, ensure that the instructions men-
tioned in this paragraph are strictly observed.
• Prior to starting electrical connection operations, dis-
connect the mains power supply.
• The motor's power cable is made of PVC and is suitable for
indoor use. For use in other environments, protect the cable
along its entire length by covering it with an appropriate cable
tray.
• The appliance's power cable cannot be replaced. If the cable
is damaged, the appliance must be scrapped.
2.1 - CONNECTING THE MOTOR TO THE PU-
SH-BUTTON PANEL AND TO THE POWER
GRID
• Caution! - The motor's power cable can only be installed in
an indoor and protected environment. If installed outdoors, pro-
tect the entire cable with a tube specially designed for protect-
ing electrical cables. The cable comprises 4 conductors: brown,
black, blue, yellow-green. To make all the electrical connections,
refer to Fig. 16.
• Connection to the mains power
To connect the motor tot he mains power, use a power cable
comprising three wires:
– brown wire, to be connected to "Live";
– blue wire, to be connected to "Neutral".
– yellow-green wire, to be connected to "Earth".
2.2 - INSTALLING THE PROTECTION DEVICES IN
THE POWER NETWORK
In accordance with the electrical installation regulations, the
network that powers the motor must have a protection device
against short-circuits and a device for disconnecting the applian-
ce from the mains power.
CAUTION! – The disconnection device must allow for the
complete disconnection of the power supply, under the Ca-
tegory III overvoltage conditions.
The disconnection device must be placed in view of the automa-
tion; if it is not visible, there must be a system for preventing ac-
cidental or unauthorised reconnection with the power grid, so as
to avoid any possible hazard. Note – The two devices are not in-
cluded in the package.

PROGRAMMING THE LIMIT SWITCHES
The motor programming process involves setting two levels:
one with the HIGH "0" limit switch function (level positioned at
the end of the upward movement) and one with LOW "1" lim-
it switch function (level positioned at the end of the downward
movement). The setting of these two levels allows the motor to
automatically stop the shutter's movement at the end of the up-
ward and downward movements. To place the two levels in the

1 - Brown: = upward or downward electrical phase.
2 - Black: = upward or downward electrical phase.
3 - Blue: = common (usually connected to neutral).
4 - Yellow-green: = earth (equipotential protection connection).
2.3 - VERIFYING THE ELECTRICAL CONNECTIONS
Once the electrical connections have been made, before pro-
ceeding it is necessary to immediately verify whether these have
been made correctly. To perform this check, lower the shutter fully
and proceed as indicated below.
01. Power the motor.
02. Press the s button and verify whether the shutter performs
the upward movement.
CAUTION! - If the shutter does not move, carry out the fol-
lowing operations:
01. Disconnect power supply from the motor.
02. On the rear of the push-button panel, invert the connection
between the brown and black wires.
03. Restore power to the motor.
04. Press the s button and verify whether the shutter performs
the upward movement.
