OK, to protect my 2 lovely computers, i decided to buy a UPS. I went with a nice belkin 660w 1100va (nice 50% off via coupon code in [H]ot deals section). Anyway, i plugged it into the outlet that my 2 computers / 21 inch monitor / router / cable mdm / speakers / light / phone/ and god knows what else is plugged into....Ran all the important stuff into the UPS for surge/UPS protection and plugged all the minor crap (speakers/light/phone) into the other surge protector i had and on the second recepticle. Even before i plugged anything into the UPS the red light on the back labled "Site Wiring Fault Indicator" lit up, i tried it on a different outlet in my room, and did not get the light. That light in the manual says that it either means

1. Open or high-resistance ground
2. Hot and neutral polarity reversal
3. Overloaded neutral circuit

anyway im not really good with electricty and those terms so i figured id throw it at you guys and see what you thought.


Also this UPS has a voltage monitor and the monitor throw's these voltages at me:

anything i should do/know?
 
If you are really concerned about that outlet(you probably should be), go to the hardware store and get an outlet tester, which will give you a slightly more detailed analysis than a simple good/no good light.

Buy an outlet tester and see what’s up. The ones the hardware store has should be able to tell you which of the first 2 problems you have, and nicer ones will inform you of the third. A knowledgeable sales associate at the hardware store should be able to point you in the right direction.

As to the possible problems, here what’s up.

1) Means the ups can NOT see a ground or the ground has an excessively high resistance. Could be as simple as a bad connection in the panel or on the outlet. This is a safety hazard.

2) Means that 2 wires (black and white) are swapped somewhere ( at the outlet or in the panel). Again, this is a safety hazard.

3) The neutral (common) bus in your electrical system is overloaded. This could be any number of things. This is also a safety hazard.

Again, if you are not familiar working with power systems I suggest that you have it checked by a professional.
