Connect the AC output cable 

 

The torque used to tighten the external forced cable fixing head of AC wiring is about 15~19N·m. 

 

In order to avoid excessive stress on the cable, the AC cable needs to enter the inverter vertically, and 

the external length of the straight section should be not less than 200mm, as shown in Figure3-33.
