You should then replace you UPS quickly.
Overload is very bad. What standby time would this UPS get?
10 seconds? 

Perhaps the problems is somewhere else:

We had some problems with our servers some years ago when our
powerline had to high fluctuations.
Sometimes there were 230V on the line sometimes there was a
"down-peak" with 208V. This didn'z do good to our servers, they
crashed.

After a review with an electrician we good a bigger power cable to our
rooms, a special power-distribution (with extra fuses) and a separate
power-circuit for our computers and after this everything was okay.

Before this we only had one power-circuit and if someone switched on
his water-heater (for tea or coffee) the power dropped (to 208V) as we
meassured.

Kind regards, Paul
