3) Pass the crimped AC wire into the AC connector.
Disassembly the inverter from the Grid:
5) The cables are inserted into the terminal accord
-
ing to the wire sequence (L1/L2/L3/N/PE), so that
the insulating terminal is flush with the surface of the
terminal, and the crimping screw torque is
2.0±0.1N•m.
6) Insert the main part of AC connector into the
terminal and hear a "click" sound.
1) Use a screwdriver to press against the unlocked
position and hold the wire nut and pull it back to
complete the separation of the male and female

8) Insert the female end of the wire into the male end
of the inverter and hear a "click".
9) Complete the installation.
3) Hold the unlocking buckle with one hand and
