Crimp the five wires (L1, L2, L3, N, PE) of the three-phase utility grid and the OT terminals firmly to ensure that
the conductor of the wire is not exposed, as shown in figure 14D below:
6. The connection of the AC cable and the connector should be correctly executed and the screws should be
tightened (tightening torque: 2N•m). See Figure 14E below.
Push the AC terminal rail into the inside of the case and fix the rail with screws. Lock the waterproof cover of
the AC junction box with the fixing screws (tightening torque: 1.5 N•m). Tighten the waterproof connector to
complete the waterproofing of the cable, as shown in Figure 14F below.
The following section describes the detailed operation of the inverter, covering pre-inspection operation, grid-tied oper-
ation, stopping and inverter maintenance.
