I need some input whether I screw something up or just a coincidence. I bought 3 brand new APC Smart UPS model SUA1500, these are high end model. I connect the 1st one to a 20A/15A wall plug, this is a delicated elec. line that I have been using for 1.5 yr. It was meant for my SUA2200 SMart UPS, but due to the fan noise, I stop using it.
There is a plastic plug at the rear end of the SUA1500, at the tail end of this plug, there is the thin plastic dangle. I simply push the plastic dangle out of the way, and within seconds, the UPS beeps and said Replace Battery.
So I stop touching that plastic tail, and everything back to normal. When I touch it again, just by pushing it out of the way so I can plug in my answering machine adaptor, the above happens again.

see the above pic., it's the plastic plug at the near top right.
Repeat the above 3rd time, I got the unit totally dead, no beep, no battery, completely malfunction.
====================
Now, I replace with the 2nd brand new SUA1500, everything works fine, but on the 4th day, there is a loud noise that sounds like gun shot, turns out it's a capacitor that blows out, the unit is still functioning, but I need to replace it, as someone has the same problem, and weeks later, there is smoke coming out of the unit.
The question is, could the above be cause by that 20A/15A wall plug? The 20/15A was installed by an electrican, I use rated 20A armor cable, and it's directly connected to the elec. panel at the basement. It's meant to fit 15A or 20A plugs.
If not, is it fair to assume it's just a coincidence to have 2 DOA?
