03. INSTALLING THE OFFSET ADAPTERS
This motor is able to detect the presence of an obstacle during the up phase. If the offset adapter is installed, the motor is also able to detect the presence of an
obstacle during the descent phase. The offset adapter must be installed in such a way that the springs are compressed by the weight of the roller shutter (an
arrow indicating the direction to compress the springs is stamped on the adapter).
WARNING
Detection of the obstacle during the descent phase is subject to some limitations. The obstacle must stop the roller shutter almost instantaneously, an obstacle
that deforms under the pressure of the rolling shutter may not be detected. The motor may not be able to detect the presence of obstacles resting on the sill with a
height of less than about 10 centimeters; moreover, to prevent incorrect detection of the obstacle, this function is inactive near the upper limit switch. In general,
obstacles may not be detected in situations where the weight applied to the offset adapter is not sufficient to adequately load the spring inserted into the adapter.
The detection function of the obstacle in descent must not therefore be intended as an absolute safety to protect the roller shutter during its descent phase, but
must be considered an instrument to limit the probability that the presence of an obstacle can cause damage to the roller shutter or to other things or people in
the range of action affected by the movement.

05.1 Warnings
This motor has been designed to work with a stable power source
circuits for lighting ● Always connect the motor to the grounding system (yellow/green)
device with a voltage category III, i.e. the distance between the contacts must be of 3,5 mm at least
with maintained position ● Command buttons are connected to the main voltage, so they must be properly insulated and protected
proportionate to their length and to the absorption of the load, and in any case not less than 1,5 mm
05.2 Power supply
The supply voltage must be applied to the brown (PHASE) and blue (NEUTRAL) wires. Connect the green / yellow wire to the grounding system.
The electrical specifications for motor operation are shown in the label applied to the tube of the motor.
05.3 Command buttons (optional)
The command buttons must be connected to the black and gray wires and they must close on brown wire. You must use buttons with spring return ("hold to run" type), do not use
buttons with maintained position. More command buttons can be connected via a parallel connection. The command buttons are subject to the mains voltage and therefore should be
properly insulated and protected. In the case where the command buttons are not used, it is necessary to ensure the isolation of black and gray wires. The buttons can be operated in
PULSE or HOLD TO RUN mode (see paragraph 14).

ANTI-LIFTING DEVICE
Make sure that the anti-lifting device is
mounted and fixed correctly and that the last
splint stays inside the guides
To avoid water infiltration, place the power cord so that it
makes a curve downwards.
