Take care to correctly identify the three phases as they are connected to the inverter on the grid
connector. The sensors of each phase must match.
Position the sensors according to the direction on the sensor (arrow).
Figure 65 - Reference to sensor direction
If it is necessary to extend the sensor connection cables, use UTP network cables or FTP grid
cables, if there is electrical/electronic noise near the wire that could cause interference.
This cable can be extended only up to a maximum of 50 metres.
Make sure to properly insulate the extension connections so as to prevent any low insulation
problems.
