So... my questions are as > follows: I went threw this before. I think you are talking about the APC ones. Those are very very touchy about power conditions (freq. etc). What you do is call APC and complain. If you complain enpought they will send you replacement ones. WE found that out when we bought a 75Kw catapiller generator (we wanted that much power to hold the air conditioning as well). If all of your questions, yes you can use serges, but it can void the warenty of the UPS, and is kinda redundant, since those UPS should have serge protectors bulitin. Stefan
