I know this has been mentioned before, can someone sumarize the problem that can occur when certain AC surge protectors are used in conjunction with UPS's with built in surge suppression? My given experience was that you plug a UPS into the wall directly, with whatever surge devices after the UPS. Never plug a UPS into a surge device, it plays havoc to the ground required by the DC to AC conversion of the swiching power supply. Depending on some surge devices, the ground becomes a virtual one. I've also been told to not unplug a UPS to test it, since it needs this ground, but turn off the breaker to it instead. This of course doesn't apply to the installs using the building wiring with the cloth covered wire and ceramic insulators nailed to the rafter, and the outlet that is split with the y type adapter screwed into the light socket, providing light as well as an oultet. Come to think of it, that's what Mr. Matsushita invented as a flash of inspiration after he was hit on the head by a pine cone. Steve L.
