Phase converter

Morning all.
I've just purchased a second hand RMK Trident mk5 1-3phase converter to power an auger on my farm.
It however hasnt come with any manual or wiring diagrams.
I've searched high and low online but with no joy.
Has anyone had any experience with this type of converter or does anyone happen to have any paperwork/diagrams I can use.
Just putting it out that I'm a farmer not an electrician so am a complete novice. Just want any info so I can pass it all on to my electrician and have him install it all.
Thanks John

You could have a look at this thread:- https://www.electro-tech-online.com/threads/3-phase-converter-schematic-miller-system.100563/

It has some useful information, even if a lot of it came from elsewhere without suitable acknowledgements. My 3-phase vehicle lift runs fine.

I don't know if your converter is of that type or not. Any photos would be useful, especially of the internals or the rating plate.
