If this is the first time for you to use the FR-S500 series, please read through this instruction manual (basic) carefully and use the inverter safely.
  • Page 2 This instruction manual (basic) provides handling information and precautions for use of the equipment. Please forward this instruction manual (basic) to the end user. This section is specifically about safety matters Do not attempt to install, operate, maintain or inspect the inverter until you have read through this instruction manual (basic) and appended documents carefully and can use the equipment correctly.
  • Page 3 2. Fire Prevention CAUTION Install the inverter on an incombustible wall without holes, etc. Installing the inverter directly on or near a combustible surface could lead to a fire. If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.
  • Page 4 (2) Wiring CAUTION Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter. The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.
  • Page 5 CAUTION The electronic thermal relay function does not guarantee protection of the motor from overheating. Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.
