Basic Operation (Front Panel) continued • If the "FAULT" icon remains lit and the alarm continues to sound after the test, the batterysupported outlets are overloaded. To clear the overload, unplug some of your equipment from the battery-supported outlets and repeat the self-test until the "FAULT" icon is no longer lit and the alarm is no longer sounding. Note: The alarm beeps once per minute. CAUTION! Any overload that is not corrected by the user immediately following a selftest may cause the UPS to shut down and cease supplying output power in the event of a blackout or brownout. • If the "REPLACE" icon remains lit and the alarm continues to sound after the test, the UPS batteries need to be recharged or replaced. Allow the UPS to recharge continuously for 24 hours, and repeat the self-test. If the icon continues to illuminate after repeated self tests, contact Tripp Lite for service. Battery replacement should only be performed by qualified service personnel. If the UPS requires battery replacement, Tripp Lite offers a complete line of replacement batteries at www.tripplite.com. Note: The alarm beeps once per minute. 3 LCD Status Screen The LCD Status Screen indicates a variety of UPS operational conditions. All descriptions apply when the UPS is plugged into an AC outlet and turned on. Note: The LCD will illuminate for 1 second when the UPS is plugged in, before it is turned on. The LCD Status Screen can be rotated for easy viewing, regardless of whether the UPS is in a horizontal or vertical position. To rotate the LCD Status Screen: insert a small tool in the slots on the sides of the screen to pop it out of the UPS housing; rotate the screen, and snap it back into the UPS housing. 3g 3 3a 3b 3c 3d 3e 3f LCD Status Screen 3a "Input Voltage" Meter: This meter measures, in real time, the AC voltage that the UPS system is receiving from the utility wall outlet. Although the Meter may occasionally display input voltages which stray outside the range of standard computer tolerance (due to poor quality utility service), rest assured that the UPS is designed (through the use of automatic voltage regulation) to continuously supply connected equipment with stable, computer-grade output voltage. In the event of a blackout (power loss), severe brownout (low power) or overvoltage (high power), the UPS will rely on its internal battery to supply computer-grade output voltage. 3b "BATTERY CAPACITY" Meter: This meter displays the approximate charge level (in 20% increments) of the UPS's internal battery. During a blackout or severe brownout, the UPS will switch to battery power, the "ON BAT" icon will be illuminated and the charge level will deplete. 3c "AVR" (Automatic Voltage Regulation) Icon: This icon will illuminate whenever your UPS is automatically correcting AC line voltage without depleting battery power. This is a normal, automatic operation of your UPS, and no action is required on your part. 3d "REPLACE" (Battery Recharge/Replace) Icon: This icon will illuminate and an alarm will sound after a self-test to indicate the UPS battery needs to be recharged or replaced. Allow the UPS to recharge continuously for 24 hours, and repeat the self-test. If the icon continues to illuminate, contact Tripp Lite for service. Battery replacement should only be performed by qualified service personnel. 4 201207108 93-2663.indd 4 9/4/2012 3:15:57 PM
