1. Connect the grounding wire at the indication label without fail.

3. Connect external alarm(no-voltage contact) at the terminal 9-10.
4. Stopping the refrigerating equipment: Turn S1 to stop. To stop for a long time, turn OFF also EB1.
5. When alarm is generated, check the abnormality content, eliminate the cause of the problem, and then turn ON the
