I don't deal with these much. I have a FSA crank on my tandem which using this kind of setup, but most of my cranks are Dura Ace or Ultegra.
First, carefully measure your chainline and that will let you know what you need to do to proceed.
Then try and find the docs online for what you have. Almost every mfg has pdf copies of their install documents on the support pages or on the product page itself.
