E6581595A-151Power factor correction capacitorPower factor correction capacitors cannot be installed on the output side of the inverter. When a motoris run that has a power factor correction capacitor attached to it, remove the capacitors. This can causeinverter malfunction and capacitor destruction.Remove the power factor correctioncapacitor and surge absorberPower factor correction capacitorU/T1V/T2W/T3Inverter IMOperating at other than rated voltageConnections to voltages other than the rated voltage described in the rating label cannot be made. If aconnection must be made to a power supply other than one with rated voltage, use a transformer toraise or lower the voltage to the rated voltage.Circuit breaking when two or more inverters are used on the same power line.MCCB1MCCBn+1MCCB3MCCB2INV1INV2INVn(circuit breaking fuse)Breaking of selected inverterThere is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than oneinverter is used on the same power line, you must select interrupting characteristics so that onlyMCCB2 to MCCBn+1 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1).When you cannot select the proper characteristics install a circuit interrupting fuse behind MCCB2 toMCCBn+1.If power supply distortion is not negligibleIf the power supply distortion is not negligible because the inverter shares a power distribution line withother systems causing distorted waves, such as systems with thyristors or large-capacity inverters,install an input reactor to improve the input power factor, to reduce higher harmonics, or to suppressexternal surges.MCCB:No-fuse breakerefesotomasyon.com -Toshiba inverter,drive,servo,plc
