NOTE: I am no expert when it comes to data center power issues. This is one of those times when a call to the vendor is worth more than the risk of upsell.
It's hard to tell from your post - are you running 230% of the rated load of the UPS? Meaning it's a 400VA UPS but you have it connected to a 1000 watt circuit and the servers connected are drawing 1000 watts? That sounds like a whole mess of problems waiting to happen because you are running way more juice through the UPS than it was designed to handle regardless of power outage or not.
Or is the panel telling you that it's 230% of the load it could provide for the rated UPS outage time? Meaning it's set up to provide 400VA for 20 minutes, but with your current load it could only last for under 10 minutes? That's less of a problem (until the power goes out).
