  • Page 4 Injury Prevention CAUTION Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur. Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur. Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur. While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.
  • Page 5 Operation WARNING When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. Since pressing the key may not stop output depending on the function setting status, provide a circuit and switch separately to make an emergency stop (power off, mechanical brake operation for emergency stop, etc).
  • Page 6 Disposing of the inverter CAUTION Treat as industrial waste. General instructions Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or partially open. Never run the inverter in this status. Always replace the cover and follow instruction manuals when operating the inverter. For more details on the PM motor, refer to the Instruction Manual of the PM motor.
