2. ELECTRICAL CONNECTION

As to the wiring diagram, connect the gearbox motor to the switch, Fig 2.
The conductors colouring mean is the following:
- Cable YELLOW/GREEN: ground connection.
- Cable BLUE: a power supply phase, common to every rotation direction.
- Cable BROWN: a power supply phase for the control motor rotation in one direction (opposite
to that got with the black cable)
- Cable BLACK: a power supply phase for the control motor rotation in one direction (opposite
to that got with the brown cable)
Note: the balancing phase between the brown and the black cable is controlled by a bipolar switch
with a permanent central zero contact (make sure the limit switches are correctly adjusted), or an
automatic return switch (in this case the system stops when the button is released).
Attention:
- Do not connect more than one motor to a single control switch.
- The possible controls centralisation can be done by the appropriate devices, which
are supplied on request.
The tubular motor is provided for intermittent functioning and not for a continuous, more
than 4 min, use.
However The motor, having a thermal protection, will stop if it reaches a high temperature due
to a sequence of several consecutive operations. (more than 10 continuous functioning without
any break). The motor starts again after a time not lower than 10 min. at the end of which the
thermal protection resets it self automatically. But after this resetting, the motor can function at
a reduce rate; the normal functioning will be possible only after a complete motor cooling (about
60 minutes).
