terminal and tighten the screws on the connector (see figure 5.22).
Please try to pull out the wire to make sure it is well connected.
Internal of AC connector signs "L1","L2","L3","N" and "PE " five connection

For all AC connections, 2.5 – 6 mm², 105°C cable is required to be used. Please make sure the
resistance of cable is lower than 1.50hm. If the wire is longer than 20m, preferred to 6mm² cable.
Please fixed cable with PH1 cross screwdriver.
Each inverter has a corresponding AC grid terminal connector. See figure 5.19.
