General Notes

1. Please ensure the reliable connection of all terminals, loose wiring will cause abnormal heating and damage to the product. 

2. Please ensure screws are torqued down properly (input (0.35-0.45) N·m, output (9-12) N·m). 

3. This product has a built-in fault detection circuit, so the R, S and T loop must be connected to the phase line, and U, V & W must  be connected to the load for proper operating. If the phase line and load are connected reversely, the product cannot work  properly. 

4. During use, it is necessary to ensure reliable grounding. 

5. Except for replacing the fuse, it is forbidden to disassemble or modify the product without authorization.
