APPENDIX A: SPECIFICATIONS
Note 1: Currently under development, unit speciî‚¿cations may be changed.
Note 2: Below 79% input voltage unit may begin parallel operation; supplementing input power with
battery power. The point at which parallel operation begins is load dependent (for a detailed
explanation of Parallel Operation see Appendix C: Parallel Operation).
Note 3: If input frequency is below 50 Hz, the input Voltage must not exceed 103% of rated input
Voltage.
Note 4: In BYPASS mode if the Input voltage is below 90% or above 110%, the UPS output will be
turned off. (See Appendix D: Bypass Under Voltage/Over Voltage)
Note 5: The input capacity is computed to include peak battery charging power.
