A typical standby UPS lets through 400V or more of surge energy. Surge energy let-through of over 400V can cause damage to sensitive components. Preceding the UPS with a Zero Surge 2R Series product protects the UPS and its connected equipment from the surges that can wear down components over time causing premature failure as well as from catastrophic surges that cause immediate damage.
The National Electric Code regulates against the daisy chaining of plugged in power devices. By rule, any device with three or more receptacles is considered a “Relocatable Power Tap”. You should not connect two or more Relocatable Power Taps into each other. That is why we developed the 2R15W as it only has two receptacles. It is allowed to plug the 2R15W into the wall outlet and plug the UPS into the 2R15W. An alternative is to plug the UPS into a branch circuit that is protected by one of our Commercial or OEM products. By code, it is not allowed to use our 6, 8, or 10 receptacle products with a UPS.
