OPT winding orientation

Hello all,
Does any of you know how are windings on TANGO XE-20S oriented? I opened the hood but trafo is submerged in black resin so I can't see the windings. The only thing I can see is two bunch of wires comming out of the resin on the oposite side of the box and are terminated at the prim/sec terminal pins. Thanks for help.
