Nice Neostar A Installation And Use Instructions And Warnings page 3

2.1) Electrical connections
!
WARNING: a reverser switch must be used during the programming operations to enable the simultaneous activation
of the electrical UP phase and electrical DOWN phase. Alternatively, the special TTU control unit can be used for the
programming operations, though it must later be replaced with the appropriate reverser switch.
!
WARNING: for motor connections, an omnipolar disconnecting device with a 3-mm minimum distance between con-
tacts must be provided for disconnection from the mains power supply (disconnecting switch or plug and socket, etc.).
!
WARNING: carefully follow all the connection instructions. If you have any doubts do not make experiments but con-
sult the relevant technical specifications which are also available on the web site "www.niceforyou.com".
An incorrect connection may be dangerous and cause damage to the system.
The cable used for the electrical connections of the NEOSTAR motors has 4 wires: electrical UP phase, electrical DOWN phase, Common
wire (usually connected to the Neutral) and Earth (unipotential protection connection). From an electrical viewpoint NEOSTAR is controlled
like any normal motor equipped with electromechanical limit switches (fig.6); on the other hand, NEOSTAR features an electronic limit switch
system programmed to stop the motor at pre-established positions. The connection devices are not supplied with the product.
Note: during the installation and adjustment operations, when no final electrical connections exist, the motor can be controlled using the
"TTU" unit.
NEOSTAR_A
The motor's electrical "up" and "down" phases are perfectly interchangeable, since the former causes the motor to rotate in one direction,
the latter in the opposite direction. The up and down movements are determined by the side from which the motor is inserted in the wind-
ing tube. To change the direction of rotation, switch the brown and black conductors.
Except for the limit switch programming operations, it is possible to connect multiple NEOSTAR motors in parallel so as to
utilise a single reverser switch.
2.2) Connector and power supply cable

WARNING: the cable must be replaced by technically qualified personnel
If it is necessary to disconnect the motor from the power supply cable proceed as shown in the figures below:
Rotate the ring nut until the
chamfer matches one of the
latch-on teeth, then release it.
Brown = electrical UP phase
Black = electrical DOWN phase
Blue = Common
Yellow/Green = Earth

Repeat the operation for the oth-
er tooth.
Bend the cable inward and
remove the protection by rotating
it gently outward.
