Hi, bought a used Ryobi 582H and local electricians are too busy to answer phone calls. (I have a job pending to run on this.)
Anyway, I have 3 phase power to hook into the transformer that came with the press. According to the labels it takes 230V to whatever the press needs (secondary is 200V, so I'm assuming output is that.)

I have 3 phase where one leg is 220v to ground the other 2 are 110v to ground. You get 220v when measuring between any two of the the 3 legs.
In the power supply box the incoming wires from left to right are black, red, white (white is the 220v leg)

The power is supplied to the terminal block on the press with the typical R S T connections. The Sakurai that this replaces had the 220v leg going to the T. Which I'm hoping is correct for this press as the compressor and Royce recirculator which are both 220v single phase got their power by connecting to the R1 and the S1 terminals.

Anyone familiar with these presses, let me know if I should hook the black to black (R), red to red (S) and white to white (T).

Thanks
 
Let me add the following: I opened the cover on the transformer. The input wires are on the 240V terminals. Should I move those to the 220V terminals, which closer to the voltage terminal to terminal on the power supply. Looking at the labeling I should have 200V output to the press from the transformer.

Now I'm thinking I should hook the compressor and Royce separately as they require 220-230V single phase.

Any help will be appreciated. Thank you

  • Okay, in case anyone else has this issue ever. My 3-phase power is 208V. I get that when measuring between any combination of the 3 leads. However to ground one is double the voltage of either of the other two. When connecting to the terminal block R and S get the 110V leads, T gets the high-leg. It only took four days to finally find someone who had an answer. Took him about 15 seconds to tell me. Anyway problem solved.
