Hi, we just ordered a kuka kr16 r2010 which is being shipped from Europe. We have 3 phase 240 in the shop but the KRC4 controller is 3 phase 400. We’re trying to have everything wired prior to arrival and looking at transformers. I found a 3p 240 to 400 transformer that is delta to delta or wye to wye. Does anyone know if the controller is delta or wye? Also, I see the controller runs at 13kva but up to 23kva. Would a 15kva transformer suffice? I know next to nothing about 3 phase. Any insight would be greatly appreciated.
