ATTENTION: The ground potential of the IRMDKG6-300W system is biased to a negative DC bus voltage potential. When measuring voltage waveform by oscilloscope, the scope ground needs to be isolated. Failure to do so may result in personal injury or death. Darkened display LEDs is not an indication that capacitors have discharged to safe voltage levels. ATTENTION: IRMDKG6-300W system contains dc bus capacitors which take time to discharge after removal of the main supply. Before working on the drive system, wait at least three minutes and until the capacitors have discharged to safe voltage levels. Failure to do so may result in personal injury or death. Darkened display LEDs is not an indication that capacitors have discharged to safe voltage levels. ATTENTION: Only personnel familiar with the drive and associated machinery should plan or implement the installation, start-up, and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage. ATTENTION: The surface temperatures of the drive may become hot, which may cause injury. ATTENTION: IRMDKG6-300W system contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing, servicing or repairing this assembly. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, reference applicable ESD protection handbook and guideline. 2 www.irf.com © 2014 International Rectifier September 25, 2014 IRMDKG6-300W ATTENTION: An incorrectly applied or installed drive can result in component damage or reduction in product life. Wiring or application errors such as undersizing the motor, supplying an incorrect or inadequate AC supply, or excessive ambient temperatures may result in system malfunction. ATTENTION: Remove and lock out power from the drive before you disconnect or reconnect wires or perform service. Wait three minutes after removing power to discharge the bus voltage. Do not attempt to service the drive until bus voltage has discharged to zero. Failure to do so may result in bodily injury or death. ATTENTION: Do not connect power factor correction capacitors to output terminals U, V, and W. Doing so may result in equipment damage or bodily injury. ATTENTION: Debris When Unpacking IRMDKG6-300W system is shipped with packing materials that need to be removed prior to installation. Failure to remove all debris and packing materials which are unnecessary for system installation may result in overheating or abnormal operating condition. 3 www.irf.com © 2014 International Rectifier September 25, 2014 IRMDKG6-300W Hardware Description J9: DC Input Inverter power stage Bus capacitor J8: Motor connector Bemf Sensing Power Supply J1: Control Connector Gate driver circuit J7: Aux supply A top view of the IRMDKG6-300Wboard is shown below. 4 www.irf.com © 2014 International Rectifier September 25, 2014 IRMDKG6-300W Connector definition Pin 1 2 3 4 5 6 7 8 9 10 N.C.
