Basic Operation continued
“VOLTAGE CORRECTION” LED: this green LED lights con- tinuously whenever the UPS is automatically correcting high or low AC voltage on the utility line without the assistance of battery power. The UPS will also emit a slight clicking noise. These are normal, automatic operations of the UPS, no action is required on your part.
“OUTPUTLOAD LEVEL” LED: this multicolored LED indicates the approximate electrical load of equipment connected to the UPS’s AC outlets. It will turn from green (light load) to yellow (medium load) to red (overload). If the LED is red (either illuminated continuously or flashing), clear the overload immediately by unplugging some of your equipment from the outlets until the LED changes from red to yellow (or green) and the alarm is no longer sounding. CAUTION! Any overload that is not corrected by the user immediately may cause the UPS to shut down and cease sup- plying output power in the event of a blackout or brownout.
“BATTERY CHARGE” LED: when the UPS is operating from utility power, this LED indicates the approximate charge state of the UPS’s internal batteries: red indicates the batteries are beginning to charge; yellow indicates the batteries are roughly midway through charging; and green indicates the batteries are fully charged. When the UPS is operating from battery power during a blackout or severe brownout, this LED indicates the approximate amount of energy (ultimately affecting runtime) which the UPS's batteries will provide: red indicates a low level of energy; yellow indicates a medium level of energy; and green indicates a high level of energy. Since the runtime performance of all UPS batteries will gradually deplete over time, it is recommended that you periodically perform a
“BATTERYWARNING” LED: this LED lights red and an alarm sounds intermittently after you initiate a self test (See “MUTE/TEST” Button description) to indicate the UPS batteries need to be recharged or replaced. Allow the UPS to recharge continuously for 12 hours, and repeat the
