Lars, The win client includes several timers that can be used to simulate what you seek. There is a timer that can be set to cause the server to shut down after X minutes on battery. You can set this to the needed times giving you the sequencing you are looking for. The down side is the issue of mid shutdown recovery. On a large UPS system with the windows client you have to cycle power to the server to get it to reboot. Unless you have a way to switch off the output that the server is on, you will have to continue the shutdown of the entire system and then trigger a restart of the UPS unit OR require manual intervention. This is exactly the point I am facing in my system. At this point we are concerned with a clean shutdown and are willing to do a manual restart.
I have about 50 ups units on campus and monitor them all with one NUT server. All of the windows clients then talk to that one master server to get the status to it's UPS unit. Mine is still a work in progress and has many things left to fix.
