AC servo motor help !

[vre]

Some more questions..
How to connect the single phase to L1/L2/L3 of driver ? phase -> L1 , neutral -> L2 , phase -> L3 OR neutral -> L1 , phase -> L2 , phase -> L3 OR it doesn't matter ?
If 1 or 2 of rectifiers fails what other failure can be happen in the drive ?
Must change the rectifiers with bigger current rectifiers ? how much bigger ?
(I have an oscilloscope so i can see if voltage is smooth when i add extra caps)
My driver specs (from here http://item.taobao.com/item.htm?id=1...catid=50006522 ):
