  • 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-0600210ENG] packed with the product carefully to use the equipment to its optimum.
  • Page 3 2. Fire Prevention CAUTION Mount the inverter on an incombustible surface. 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.

    Troubleshooting 3.2.2 Motor rotates in opposite direction Check that the phase sequence of output terminals U, V and W is correct. Check that the start signals (forward rotation, reverse rotation) are connected properly. Check the setting of Pr. 17 "RUN key rotation direction selection". 3.2.3 Speed greatly differs from the setting Check that the frequency setting signal is correct.
