Does it have a terminal for the DC link bus? Thank you _{6SL3225-0BE37-5AA0 , SINAMICS G120 POWER MODULE PM250 WITH BUILT IN CL.

(I think in your case you wanted it because of the UPS) Maybe you should use another power module or drive system. Maybe it would also make sense to contact your local Siemens sales partner to search for a suitable solution for your usecase.
