  • Page 7: Chapter 1 Safety Precautions

    Chapter 1 Safety Precautions Chapter 1 Safety Precautions 1.1 Operation Precautions 1.1.1 Before Power Up Caution The line voltage applied must comply with the inverter’s specified input voltage. Danger Make sure the main circuit connections are correct. L1(L), L2, and L3(N) are power-input terminals and must not be confused with T1, T2 and T3.

  • Page 8: During Power Up

    Chapter 1 Safety Precautions 1.1.2 During Power up Danger The inverter still has control power if the time of power loss is very short. When the power is re-supplied, the inverter operation is controlled by F41. The inverter operation is controlled by F04 and C09 and the status of (FWD/REV RUN switch) when power is re-supplied.
