  • Page 10: Points For Handing

    Points for Handling Follow this manual and precautions when handling this unit. Incorrect handling could lead to inhibited operation or a drop operating life. In the worst case, the inverter could be damaged. Use within +10%, −15% of the tolerable input Power supply voltage range, and within ±5% of the tolerable input frequency range.

  • Page 11: Special Precautions

    Special Precautions ♦ ♦ ♦ ♦ Use your inverter only within tolerable ambient temperature range. (–10°C to 50°C) Because the life of the inverter is greatly affected by ambient temperature, do not use it outside the specifications. Also, pay attention to the installation direction's and conditions.
  • Page 12 ♦ ♦ ♦ ♦ If a magnetic contactor is connected to the power supply side or the load side of the inverter, never use it to start or stop the motor (inverter). Switching the inverter on the power supply side ON and OFF frequently by a magnetic contactor, can cause the inverter to malfunction.
