Hi i have a canopy fan to wire up the problem is a 3rd party has left no wiring diagram for it. It will be working of a speed controller which has the connections N L E U1 U2 1 2 . The Fans make is RUCK Ventilation DVNI 500 E4 Single phase it has 5 conenctions at the isolator. It is numbered such as 1 3 5 7 9 and on the other side it is 2 4 6 8 10 this side has the cables going to the fan connected in 2 4 and 6 but im not sure which is which as there is no wiring diagram left on site any help would be appreciated.
 
i would think that the speed controller has the numbers matching. i.e. 1-2, 3-4,5-6,7-8.
