G) Confirm the selected grid system is compatible with the PV inverter.
Then connect the AC cables to correct positions as per the symbol on
the configuration label for the AC cables in the wiring box.
Figure 7.2.6 shows the AC cable connections when a 208V grid system
is applied with the PV inverter. L-phase cable is connected to position (1)
pole, Neutral cable is connected to position (2) pole and ground cable is
connected to the ground symbol pole. On the other hand, please ensure
the setting of the AC DIP switch has been set correctly with the applied
grid system.

H) Tighten the screws for the AC cables with the required torque values as
listed in the Table 7.2.2. Then turn on the circuit breaker from the utility
panel or switchboard, and use a multi-meter to measure whether the AC
voltage of PV system is normal and the connection is correct.
I)
Check the condition of the conduits again to ensure all conduits are
