I'm assuming one white wire will go to the ballast (Live), yellow possibly earthing the fitting somewhere (Earth)? and the remaining one would be (Neutral)? Just a guess
If you stick your finger in the hole where the cables come through (turn power off), you should hopefully be able to feel a joist where the fitting bracket will attach
Don't know if this little snippet from the instructions is of any help to you.
If not you could always convert to farads yourself as in the example. Hope you get it sorted
