  • Page 1 Drive INSTRUCTION MANUAL...
  • Page 3 Safety Instructions Preface Thank you for choosing DOOCH’s high performance NSQ-Drive series. Describing specification, installation, operation, function, and maintenance of the NSQ-Drive series provided for the users who are familiar with and having basic experience in using a variable frequency drive.
  • Page 4 Safety Instructions Do not remove the cover while power is applied or the unit is in operation. Otherwise, electric shock could occur. Do not run the inverter with the front cover removed. Otherwise, you may get an electric shock due to high voltage terminals or charged capacitor exposure.
  • Page 5 Safety Instructions Cautions for Use A. Transportation and Installation Be sure to carry VFD in a proper way suitable for its weight, or it may result in damage to the VFD. Be sure to use heat-treated wooden crate when you adopt wooden packaging for the product. Do not pile up VFD's above allowable limit.
  • Page 6 Safety Instructions C. Adjustment before starting trial operation Do not supply the excessive range of voltage displayed in the user manual to the each terminal. It may cause damage to the inverter. Current hunting can be occurred in the low speed territory during testing. It occurs where the capacity is above 110kW with no-load and the axis is not connected.
