WebMonitor the voltage across the capacitor during the reforming process. It will probably start low and rise over time. When it is at or near the rated voltage the process is done. If the voltage never gets near the rated voltage the capacitor is hopeless and don’t use it. Edit: Reforming seems to be mostly for older capacitors. Web1) With A.C. power turned OFF, connect 3-phase power supply to the line inputs on the VFD. 2) Turn A.C. voltage supply ON. The VFD should run through its normal "Boot-Up" display, and finish at the "rOFF" or "cOFF" readout. 3) Leave the VFD powered on for a period of at least 60 minutes. 4) Turn A.C. voltage supply OFF. how to define string array https://britfix.net
