A-1 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-0600026] packed with [...]

A-2 2. Fire Prevention CA UTION Mount the inverter to incombustible material. M ounting it to or near co mbustible material can cause a fire. If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire. Do not connect a resis tor directly to the DC terminals P( + ), N( − ). This could ca[...]

A-3 (2) W iring CA UTION Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter. The connection orientation of the output cable s U, V, W to the m otor will affect the direction of rotation of the motor. (3) Trial run CA UTION Check all parameters, and ensur e [...]

A-4 (6) Maintenance, inspection and parts replacement CA UTION Do not carry out a megger (insulation resist ance) test on the c ontrol circuit of the inverter. (7) Disposing of the inverter CA UTION Treat as industrial waste. (8) General i nstructions Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or[...]
