Line R 1200

This was originally posted on APC forums on 9/11/2010

I use four Line R 1200's in my home.
Regardless what I have written below...
I am deeply grateful for this unit.
The quality of our computer and entertainment life
would be much lower without APC.

That said...
I have "burned out" 4 units over the last 4 years.
Where I live, we have frequent black outs and frequent surges and dips.
Sometimes daily blackouts.
Every once in awhile, when the power comes back on,
a unit will start up and then go to flashing all three lights.
Usually when this happens, I turn it off,
turn it back on and it goes to a solid green.
But periodically I turn it back on and all three lights flash.
This is when I have usually gotten rid of the unit.

I "know the math" and have carefully calculated my loads on each one.
Fact: Where I live the electricity for all real estate is never grounded.

1) What does it mean when all three lights won't stop flashing?
This has typically been when I got rid of a unit.

2) Any ideas what could be "burning out" my units?
It happened once on each of different locations.
Each time it happened, the unit that fried would be the only one that fried that day.

3) If you do have some ideas...what might I tell or request of an electrician here?

4) I have never put anything into the fourth outlet. Can someone please explain to me
what that outlet is for and if it's ok to treat it simply as an additional outlet.

I sure wish APC would make this unit with a fuse.
A replacement unit costs me around $110 with shipping...ouch!
But...for the price... there's nothing I can find that's anywhere close as effective or durable.

Thanks to anyone responding!
