SOLVED
For the new PC generation we also have new UPS (VAU02, R911385289). The bridging time is 3 mins at 50% battery charge. 24 V connecting cable and RS232 cable, both 5 meter, are included. The parameters how the UPS has to react can be easily managed by the PR/VR dashboard at the menu monitor service.
Be aware, that the VAU01, the UPS for the VPB40.x is not compatible to the new UPS
