    • To order a copy of this manual, or if your copy has been damaged or lost, contact your Yaskawa representative. • Yaskawa is not responsible for any modification of the product made by the user, since that will void the guarantee.

  • Page 3: Notation For Safety Precautions

    NOTATION FOR SAFETY PRECAUTIONS Read this instruction manual thoroughly before installation, operation, mainte- nance, or inspection of the VS mini. In this manual, safety precautions are classi- fied as either warnings or cautions and are indicated as shown below. WARNING Indicates a potentially hazardous situation which, if not avoided, may result in death or serious injury.
  • Page 4 PRECAUTIONS FOR UL/cUL MARKING • Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON. • The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electric shock, disconnect all power before ser- vicing the Inverter, and then wait at least one minute after the power sup- ply is disconnected.

  • Page 5: Receiving The Product

    RECEIVING THE PRODUCT CAUTION (Ref. page) • Do not install or operate any Inverter that is damaged or has missing parts. Failure to observe this caution may result in injury or equipment damage. MOUNTING CAUTION (Ref. page) • Lift the Inverter by the heatsinks. When moving the Inverter, never lift it by the plastic case or the terminal cover.
  • Page 6 WIRING WARNING (Ref. page) • Only begin wiring after verifying that the power supply is turned OFF. Failure to observe this warning may result in an elec- tric shock or a fire. • Wiring should be performed only by qualified personnel.
  • Page 7 CAUTION (Ref. page) • Verify that the Inverter rated voltage coincides with the AC power supply voltage. Failure to observe this caution may result in personal injury or a fire. • Do not perform a withstand voltage test on the Inverter.
  • Page 8 OPERATION WARNING (Ref. page) • Only turn ON the input power supply after con- firming that the front cover, top cover, and bot- tom cover are in place. Do not remove the covers while current is flowing. Failure to observe this warning may result in an elec- tric shock.
  • Page 9 WARNING (Ref. page) • If an alarm is reset with the operation signal ON, the Inverter will restart automatically. Reset an alarm only after verifying that the operation sig- nal is OFF. Failure to observe this warning may result in injury. •...
  • Page 10 CAUTION • All the constants set in the Inverter have been preset at the factory. Do not change the settings unnecessarily. The Inverter may be damaged. MAINTENANCE AND INSPECTION WARNING (Ref. page) • Never touch high-voltage terminals on the Inverter. Failure to observe this warning may result in an elec- tric shock.
  • Page 11 CAUTION (Ref. page) • The control PCB employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. • Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit.
