Note1: Below 77% input voltage unit may begin parallel operation; supplementing input
power with battery power. The point at which parallel operation begins is load
dependant (for a detailed explanation of Parallel Operation see appendix D).
Note2: Input voltage range is limited in bypass for load protection. (For a detailed
explanation of Bypass Undervoltage / Overvoltage see appendix E.)
