INPUT voltage meter: This meter measures the AC voltage that the UPS system is receiving from the 
utility wall outlet. The UPS is designed to continuously supply connected equipment with stable output 
voltage. In the event of a complete power loss, severe brownout, or over-voltage, the UPS relies on its 
internal battery to supply consistent 110/120 output voltage. The INPUT voltage meter can be used as 
a diagnostic tool to identify poor-quality input power. 
OUTPUT voltage meter: This meter measures, in real time, the AC voltage that the UPS system is 
providing to the computer during normal AC/Utility Power mode, and battery backup mode. 
ESTIMATED RUNTIME: This displays the run time estimate of the UPS with the current battery 
capacity and load. 
NORMAL icon: This icon appears when the UPS is working under normal conditions. 
BATTERY icon: During a severe brownout or blackout, this icon appears and an alarm sounds (two short beeps followed by a pause) to indicate 
the UPS is operating from its internal batteries. During a prolonged brownout or blackout, the alarm will sound continuously to indicate the UPS’s 
batteries are nearly out of power. You should save files and turn off your equipment immediately or allow the software to shut the system down. 
OVER LOAD icon: This icon appears and an alarm sounds to indicate the battery-supplied outlets are overloaded. To clear the overload, unplug 
some of your equipment from the battery-supplied outlets until the icon turns off and the alarm stops. 
BATT. CAPACITY meter: This meter displays the approximate charge level of the UPS's internal battery in 20% increments. During a blackout 
or severe brownout, the UPS switches to battery power (the BATTERY icon appears) and the battery charge level decreases. 
LOAD CAPACITY meter: This meter displays the approximate output load level of the UPS battery outlets in 20% increments. 
FAULT: The following number appears if there is a problem with the UPS. Press the POWER button to turn the UPS off. 
E22: Battery Mode or AC/Utility Power Mode Overload fault (Unplug at least one piece of equipment from battery outlets and turn the 
UPS on again.) 
E21: Battery Output Short fault (Unplug at least one piece of equipment from battery outlets and turn the UPS on again.)

Advanced Energy-Saving Patented Bypass Technology 
CyberPower’s patented GreenPower UPS™ with Bypass Technology reduces UPS energy costs by up to 
75% compared to conventional UPS models. Even when utility power is normal, conventional UPS models 
constantly pass power through a transformer. By contrast, under normal conditions the advanced circuitry 
of a GreenPower UPS™ bypasses the transformer. As a result, the power efficiency is significantly 
increased while decreasing waste heat, using less energy, and reducing energy costs. 
When an abnormal power condition occurs, the GreenPower UPS™ automatically runs power through its 
transformer to regulate voltage and provide “safe” power. Since utility power is normal over 88% of the time, 
the GreenPower UPS™ operates primarily in its efficient bypass mode. 
The GreenPower UPS™ is also manufactured in accordance with the Restriction on Hazardous Substances (RoHS) directive making 
it one of the most environmentally-friendly on the market today.
