  • Page 2 Thank you for choosing this Mitsubishi Transistorized inverter. This instruction manual (detailed) provides instructions for advanced use of the FR- S500 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual and the instruction manual (basic) [IB-0600151E] packed with the product carefully to use the equipment to its optimum.
  • Page 3 2. Fire Prevention CAUTION Install the inverter and brake resistor on an incombustible wall without holes, etc. Installing the inverter and brake resistor 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, capacitor type 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.
