Hello, I have a Sitral rack with 9 Lawo modules and a N224a psu from Germany. it is obviously set up for 240v power and I tried plugging it in with a 120v plug adapter with no luck. Does anyone have the pin out sheet/info/experience with getting these to work with 120v? I'm a noob at this so please take it easy :-\

Thank you for your time and knowledge!

This is how the back it wired atm -

I can't really see any numbers on the connector.
According to the schematic you probably have to wire the primary in parallel for 120V. So connect 55 to 57 and connect 56 to 58.
Connect mains plug live to 60, neutral to 59 and earth to 61.
Also check the fuse! For 120V you need 0,5A fuse.

But maybe post a more detailed picture of the connector first.
