  • Page 6: Precautions

    SENLAN SB40 GENERAL 1.5 Precautions Read the following items before installing, wiring, operating and maintaining the product, and always bear them in your mind. Precautions in this manual fall into two types： Danger indicates that errors in operation may lead to death or heavy injury to people or may destroy the inverter.
  • Page 7 SENLAN SB40 GENERAL Caution ‧ Install the inverter firmly on an object capable of bearing its weight. Otherwise, the falling of the inverter may cause injury or damage. ‧ Do not drop metallic material in the inverter. That may lead to accident.
  • Page 8 SENLAN SB40 GENERAL 1.5.3 Operation Danger ‧ Switch on the inverter power only after the wiring is completed and the cover board is attached. Otherwise, electric shock may occur. ‧ Do not touch inverter terminals when electrical power is going to the inverter even if the motor is stopped.
  • Page 9 SENLAN SB40 GENERAL 1.5.4 Maintenance Danger ‧ 10 minutes after power-off, measure the DC voltage between P and N terminals with a multimeter. Only when this voltage drops below 36V, can the inverter be inspected and repaired. Otherwise, electric shock or injury may occur.
