I currently have an SMT 1500 UPS. I have read and searched varying discussions, including the FAQ, which advise against plugging a UPS into a surge protector. But, the reasons given in the FAQ are vague. Most online discussions find no issue with doing so, although the reasons given are anecdotal or abstract. The FAQ mentions power could be drawn away from the UPS. But, if the UPS is the only thing plugged into the surge protector, what is the issue? The FAQ also mentions clean power. Would there be some disturbance via the surge protector due to the EMI / RFI noise filtering? Again, the searches and FAQ are helpful, but I am hoping for a definitive "yes" or "no" answer, as well as rationale for said reasons.
I wanted to run my SMT 1500 into something like the APC P11VNT3. The extra surge protection would be nice in my area. I would rather sacrifice the surge protector as opposed to the UPS, for obvious price reasons. Is said surge protector good enough / compatible with the SMT 1500 (assuming plugging only the UPS into the surge protector is deemed acceptable)?
I have seen comments from 2010 searches which suggest ONLY a UPS into a surge protector should be fine (APC knowledge base article 1372 addresses this). Again, my hope is to simply make sure. And, if I am being overly redundant, feel free to point that out as well!
Thank you,
Mark
