|
><P
|
|
>To test your UPS, throw the circuit breaker with the UPS on it to
|
|
simulate and outage and see how the transition goes. Note that in general
|
|
testing an UPS by pulling the plug from the wall is not a good
|
|
idea. Electronics like to always have a good ground reference. If you
|
|
unplug a UPS, it's still powered but now has what electricians call a
|
|
"floating ground". Not only can this be bad for electronics, but it can be
|
|
quite dangerous as well. It is likely that unplugging just about any UPS
|
|
for a short amount of time isn't likely to result in disaster (don't take
|
|
our word for it, though!), but in all cases, throwing a circuit breaker
|
|
would be a better thing to do.</P
|
|
><P
|
|
>It might be useful to install a GFI (Ground Fault Interrupter) on your
|
|
UPS-covered outlets to facilitate this testing without having to throw a
|
|
breaker, especially if you don't have your UPS protected machines on an
|
|
isolated circuit (which you probably should). These are the sockets found
|
|
in most modern kitchens and bathrooms with a red and a black button. You
|
|
push the latter to cut power and the former to restore power.</P
