Hi, I wanted to know if there is any restriction or rules when installing a Variable Frequency Drive, which will be powered using 750VDC (Voc) open circuit voltage. This means that the operating voltage will be about 600-620. or 480VAC. Is there any special regulations, equipment requirements as far as wires, conduits, disconnects? Does UL1741 have any regulations about this?
Thank you
Juan
