  • Page 26: Precautions As To Operation

    9. Precautions as to operation CAUTION 9.1 Precautions as to use (1) A high-voltage circuit is provided on the printed circuit board. Never touch it by hand. (2) The internal circuit remains charged with high voltage for some time after the power is turned off. Wait for one minute after turning off the power before inspection.
  • Page 27 (13) If the supply voltage drops when the power supply is interrupted instantaneously, the inverter will detect the undervoltage and shut off the output. When the supply voltage is restored, the inverter automatically resumes operation. Check the system consistency. (14) The heat sink on the side of the inverter becomes hot. Never touch it during operation or before a sufficient time passes after the inverter is stopped.
  • Page 28 (9) When using the inverter for parallel operation of more than one mo- tor, select an appropriate inverter capacity so that the total rated current will be lower than the rated current of the inverter. When the total of motor output is used for selection, the rated current of the inverter may be exceeded depending on the type of motor.
