Delta RPI-H3 - AC Grid Connection: L + N + PE

5.2 AC Grid Connection : L + N + PE
WARNING !
Before commencing AC wiring, please ensure AC breaker is switched off.
For RPI-H5, users must aware that AC configuration Setting must be set correctly
otherwise this device can not work. There are two types of AC configurations (shown
in figure 5-3) that are used in electricity systems. For “AC Configurat.” setting please
see chapter 7.2.2
Star configuration (3 phases + Neutral): L–N (default),
The voltage between each phase and the neutral is
230/220 V. The voltage between two phases is 400/380V.
Delta configuration (3 phased wires only) : L–L, The voltage
between two phases are 230/220V. As there is no neutral,
there is no phase-neutral voltage.
