mutlple DALI ballast, wiring, series or parallel?

[robertvo]

Hi,

I've installed one dimmable ballast, dali controlled, dimming works great.
Now I want to add one more lightbar. Question is, how do I do the wiring of the control wires when I want to implement a second (or third) ballast?
Do I wire it parallel or in series with the exsisting one?

Thanks

DALI terminals are connected in parallel to the bus.
