Yes both UPS units are on different power supplies. MINSUPPLIES is set to 1. Afaik NUT waits for OB and LB before shutting down the system. Is there a way to change this behavior to only wait for OB? Then I would use FINALDELAY in case the power outage doesn't last long.
I already tried to change the battery.runtime.low setting over the webinterface of the CS121 (snmp is readonly) but with our AEG UPS, this didn't work as expected(seems like a firmware bug) and I need to work around this problem. I'm already in contact with AEG but I also have a bunch of UPS units from other manufacturers to cover with the same controller card and different (potentially buggy) firmware...

If these two UPS units are on different power supplies then it is possible for one to reach x minutes on battery while the other is still on wall power. > Are timers the only possible solution to this problem? NUT provides the MINSUPPLIES declaration in upsmon.conf to handle multiple UPS units when the setup uses status [OB] to call for a system shutdown, but if your shutdown plan is for a time based solution, then you could use NUT utility upsrw to set the battery.charge.low value to a high value corresponding to x minutes. This would get around the need for an external script.
