I have encountered an issue on a piece of equipment that my client has purchased and plans to install in their facility. I would like to know if there is anything illegal code wise regarding what the equipment manufacturer is asking us to do. They have sold the client a submersible motor and pump that has a nameplate rating of 230V. What they are telling us is that they have been doing this for years and have had no issues. They are taking this motor and running it with a VFD at 455V and 100HZ. They have told us that they are using a Volts/Hz ratio to run this motor and run it safely at 455V even though the name plate rating is only 230V.
Can you think of any legal concerns regarding doing exactly what the equipment manufacturer has recommended? Any insight you could provide would be a great help.
