(Cautions)
1. Connect the grounding wire at the indication label without fail.
2. The components marked * need to be acquired locally. However, *2 is included in the showcase.
3. Connect external alarm (no-voltage contact) at the external alarm terminal base.
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 power.
6. Local wiring should be shielded cable.
