Transformer Wiring Diagram 3

[rockman7892]

I am trying to find a wiring diagram for a particular European (German manufacturer) transformer but have had no luck searching online. I am trying to determine how the connections are made on this transformer and the voltage readings I'm getting are strange and are not lending any clues. I am therefore after a wiring diagram to see how its connections are made. The transformer has the following information:

Jacke Transformatoren Gmbh
Einphasen-Transformator nach UDE 0550/0570
Art.Nr.-EAM53,2460230
Ser Nr:2014159V820 2
Typ: EAMS 3,2 KVA
PRI: 460V +/- 7.3A
SEC: 230V 13,9A
Lio IP00 60/60Hz T40/B

Does anyone know where I can find a wiring diagram for such a transformer? It has two transformers windings and cores connected in parallel but I cannot seem to figure out exacty how they are wired.

Thanks for the link, it cleared up the polarity issue with these transformer for me.

So when ScottyUK referes to connecting windings in anti-phase, how does this corrospond to add or sub polarity. If I have two additive transformer winding sets, how do a make sure they are in antiphase when connecting them in series? Would I make sure that the X1 terminal for the winding on the left was connected to the X2 terminal for the winding on the right?

In the windings are inparallel then the X1's and X2's need to match.
