Basic Operation continued "OVERLOAD/CHECK BATTERY" LED: this red LED lights continuously after a selftest to indicate the capacity of the battery-supported outlets has been exceeded. To clear the overload, unplug some of your equipment from the battery-supported outlets; then use the ON/OFF/TEST button to run a Self-Test. If the UPS continues to detect an overload, remove more equipment and repeat the self test until successful. CAUTION! Any overload that is not corrected by the user immediately following a self-test may cause the UPS to shut down and cease supplying output power in the event of a blackout or brownout. The LED flashes to indicate the battery needs to be recharged or replaced. If the LED flashes (and a continuous alarm sounds) during a prolonged blackout or brownout, the UPS's batteries are nearly out of power; you should save files and shut down your equipment immediately. If the LED flashes following a UPS self-test (after the UPS is turned ON), it may indicate that the battery needs to be replaced. Allow the UPS to recharge continuously for 12 hours; then use the ON/OFF/TEST button to run a Self Test. If the LED continues to flash, contact Tripp Lite for service.
