User Manual 14 < back to the table of contents > DAT-Module Module Configuration Description Grid Connection Choose 1-phase or 3-phase mode: 1-phase mode 3-phase mode Installation position Top Bottom Rotating field 123 321 Current Normal direction Inverted direction In this configuration, when energy flows in direction “3” (red arrow), the power is displayed with a positive sign. If the PV system feeds energy into the grid (direction “1”, green arrow), the power is shown with a negative sign. “Total actual imported energy” refers to the energy drawn from the grid. “Total actual exported energy” sums the energy fed into the grid by the PV system. PV System Choose 1-phase or 3-phase mode: 1-phase mode 3-phase mode Installation position Top Bottom Rotating field 123 321 Current Normal direction Inverted direction The DAT-Module is installed after the main switch. To display the generated power with a positive sign, the “normal direction” must be selected for current flow. In this case, the energy produced by the PV system is shown under “Total actual imported energy”. Main Distribution Choose 1-phase or 3-phase mode: 1-phase mode 3-phase mode Installation position Top Bottom Rotating field 123 321 Current Normal direction Inverted direction The DAT-Module is installed after the main switch. To display the power with a positive sign in the web UI for energy flows in directions 2 (yellow arrow) and 3 (red arrow), the “normal direction” must be selected for current flow. “Total actual imported energy” in this case refers to energy drawn from both the grid and the PV system. Electric Motor Choose 1-phase or 3-phase mode: 1-phase mode 3-phase mode Installation position Top Bottom Rotating field 123 321 Current Normal direction Inverted direction The motor operates with a counterclockwise rotating field. The phase conductors are swapped before the DAT-Module. To ensure correct measurement, the rotation field must be set to the sequence 3-2-1.
