IMHO, a properly designed backup power system should always incorporate a cascaded approach to applying surge protection working in conjunction with a UPS. The idea is the first surge unit, (upstream Surge Protection Device) mitigates the brunt of the surge energy while the second unit (the UPS) reduces any remaining surge energy to an inconsequential level. Here a UPS delivers only a second-level protection against surges.
Does this sound like a viable approach?
Even something very affordable like, for example, Amazon Basics 12-Outlet Power Strip Surge Protector providing 4,320 Joule energy rating should adequately protect your much more expensive UPS...
And yet CyberPower recommends the UPS be plugged directly into the wall outlet! They say connecting the UPS to an AC power source through a surge protector MAY affect how the UPS measures and reports incoming line power. This MAY cause the UPS to switch to battery power when it should normally operate in line mode. Additionally, intermediate devices such as a surge protector MAY compromise electrical ground connectivity, which is necessary for the UPS to operate optimally and provide the specified surge protection.
I am just a humble musician, not an electrical engineer... Could you please, dear experts, help me understand what is really happening here?
