Probably, but I am guessing that a line conditioner doesn't count as an "other device"
From the Smart 1000 manual
Connect your UPS directly to a properly grounded AC power outlet. Do not plug the UPS into itself; this will damage the UPS.
Do not modify the UPS's plug, and do not use an adapter that would eliminate the UPS's ground connection.
Do not use extension cords to connect the UPS to an AC outlet. Your warranty will be voided if anything other than Tripp Lite
surge suppressors are used to connect your UPS to an outlet.
If the UPS receives power from a motor-powered AC generator, the generator must provide clean, filtered, computer-grade output.
I am thinking if you can plug this thing into a motor powered AC generator, one should be able to plug it into a line conditioner. Of course if I am wrong, and someone's house goes up in flames, I wouldn't want to take responcibility!
