Cut off the general voltage and reverse two phases of the power supply cable of the switchboard.
Cut the general voltage off and reverse two drivers on power supply leads on the inverter contact or of the
pump inquestion.
Cut the general voltage off and reverse two leads on power supply terminals of the contactor (or of direct
contactor) of the pump in question.

The installation is prepared for MANUAL working
With the installation and the switchboard set for manual working, press key (12)
If pumps, either fed by an inverter or fed directly, have an inverted sense of rotation, proceed as follows:
If on the contrary the sense of rotation of the pumps is inverted only when fed by inverter, proceed as follows:
If one or several pumps supplied by the inverter do not have the same sense of rotation, proceed as follows:
If one or some of the pumps directly fed have a reversed sense of rotation, proceed as follows:
n.1 pump will enter in function; push again the same key to stop the pump and to control the sense of rotation of pump n.2 pump
therefore the one of all other.
In the case where pumps would not turn all in the same sense, before proceeding to the correction check sense of rotation of
pumps directly fed (and no from an inverter).
Press again and check the direction of rotation of pump no. 2. Do the same operation on all other pumps, always with pump n.1 in
operation. Stop pump n.1; enable pump n.2 as first pump and check the sense of rotation of pump n.1.
Pump n.1 will enter in function controlled by the inverter and, while maintaining it in operation, start pump 2 by pressing the key (13)

CHECK THE SENSE OF ROTATION OF PUMPS DIRECTLY STARTED
The inversion of power phases of the inverter does not produce any effect on the sense of rotation of the
pumps.
WARNING
Cut the general voltage and reverse two phases of power supply cable on the inverter (outlet terminal of the
inverter)
