2.7.2 Input Connection for Multiple Power Supplies
If multiple 5kW or 10kW models are connected to the grid, it is recommended to distribute the access points in a
balanced manner as shown in the figure below. When the 15kW model is connected to the three-phase power
grid, there is no need to consider the imbalance of the power grid.
