NOTE
If power control is enabled, it is important to respect the order of grid lines
connection to the inverter. A 120deg phase difference should be kept
between L1 to L2 and between L2 to L3 (L1-L2-L3 and not, for example L1-L3-
L2).
If the grid lines are not in this order, an error is displayed on the LCD screen
and the inverter will not produce power.
7. Connect the wires to the appropriate terminal block connectors in the inverter.
Tighten the terminal block screws with a torque of 1.2-1.5 N*m / 0.88-1.1 lb*ft.
8. Check that the wires are fully inserted and cannot be pulled out easily.
9. Tighten the AC cable gland with a torque of 2.8-3.3 N*m / 2.0-2.4 lb*ft.
10. Verify that there are no unconnected wires to the inverter and that the unused
terminal screws are tightened.
