No, the equipment only requires 120 volt.
Another question: what im feeding is a DP located on the roof of a building. I need to install a new service meter fed from the building multi-meter center. The new meter needs to be separate so its getting mounted adjacent to the existing center. The new panel on the roof is going to be a 200 amp panel with a 200 amp main breaker. What is the recommendation for the new meter? Should it just be a meter/disconnect or should it also contain a 200 amp breaker?
Thanks

Electrically speaking, you merely connect to two of the lines and the neutral. Keep in mind, though, that you'll have 120v line-to-neutral and 208v line-to-line, so make sure that any 240v loads will work on 208v.
Now seeing your second post, stating only 120v loads, I agree that a 3-phase panel would be better, requiring a smaller-sized feeder for the same Kva capacity, except with one more conductor, of course.
As long as you're outdoors (the entire feeder, that is), you don't have to place the disconnect at any particular point. If I'm not mistaken, the main disconnect can be the one in the roof-top panel.
Uh, what's a DP? :-?

DP=Distribution Panel......possibly?

DP for distribution panel- Ill use MDP for main distribution panel referring to the panel on the roof.
Thanks Larry,
Im required by building owner to put the meter in the meter room located indoors, 4 floors down. My first instinct is to put a meter/disconnect in the meter room and only have a single 200 amp breaker at the MDP on the roof so i can avoid any coordination issues. any issues with that?
That said, mounting the meter next to the service, wouldnt i have to maintain the 10 ft tap rule? or would that not apply and why?
