Charge the battery. Batteries require recharging after extended outages. They wear faster when put into service often or when operated at elevated temperatures. If the battery is near the end of its service life, consider replacing the battery even if the replace battery LED is not yet lit. ALL LEDS ARE LIT AND THE UPS EMITS A CONSTANT BEEPING Internal UPS fault. Do not attempt to use the UPS. Turn the UPS off and have it serviced immediately. FRONT PANEL LEDS FLASH SEQUENTIALLY The UPS has been shut down remotely through software or an optional accessory card. None. The UPS will restart automatically when utility power returns. ALL LEDS ARE OFF AND THE UPS IS PLUGGED INTO A WALL OUTLET The UPS is shut down and the battery is discharged from an extended outage. None. The UPS will return to normal operation when the power is restored and the battery has a sufficient charge. 11 PROBLEM AND POSSIBLE CAUSE SOLUTION THE OVERLOAD LED IS LIT AND THE UPS EMITS A SUSTAINED ALARM TONE The UPS is overloaded. The connected equipment exceeds the specified “maximum load” as defined in Specifications at the APC web site, The alarm remains on until the overload is removed. Disconnect nonessential equipment from the UPS to eliminate the overload. The UPS continues to supply power as long as it is online and the circuit breaker does not trip; the UPS will not provide power from batteries in the event of a utility voltage interruption. If a continuous overload occurs while the UPS is on battery, the unit turns off output in order to protect the UPS from possible damage. THE REPLACE BATTERY LED IS LIT Replace Battery LED flashes and short beep is emitted every two seconds to indicate the battery is disconnected. Weak battery. Failure of a battery self-test. Check that the battery connectors are fully engaged. Allow the battery to recharge for 24 hours. Then, perform a self-test. If the problem persists after recharging, replace the battery. The UPS emits short beeps for one minute and the replace battery LED illuminates. The UPS repeats the alarm every five hours. Perform the self- test procedure after the battery has charged for 24 hours to confirm the replace battery condition. The alarm stops and the LED clears if the battery passes the self-test. THE SITE WIRING FAULT LED IS LIT The site wiring LED is lit (rear panel). 120V models only. The UPS is plugged into an improperly wired utility power outlet. Wiring faults detected include missing ground, hot-neutral polarity reversal, and overloaded neutral circuit. Contact a qualified electrician to correct the building wiring. THE INPUT CIRCUIT BREAKER TRIPS The plunger on the circuit breaker (located above the input cable connection) pops out. Reduce the load on the UPS by unplugging equipment and press the plunger in. AVR BOOST OR AVR TRIM LEDS LIGHT AVR Boost or Trim LEDs light Your system is experiencing excessive periods of low r high voltage. Have qualified service personnel check your facility for electrical problems. If the problem continues, contact the utility company for further assistance. 12 PROBLEM AND POSSIBLE CAUSE SOLUTION UTILITY CIRCUIT BREAKER TRIPS Utility circuit breaker trips during normal operation. 100V models: In order to operate at the full VA rating of the 1500VA product, the supplied 15A plug must be replaced with a 20A plug. This change must be performed by qualified service personnel. UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS UPS input circuit breaker tripped. Reduce the load on the UPS by unplugging equipment and resetting the circuit breaker (on the back of UPS) by pressing the plunger in. Very high, low, or distorted line Move the UPS to a different outlet on a different circuit. Test the input voltage. Inexpensive fuel powered voltage with the utility voltage display (see below). If acceptable to the generators can distort the voltage. connected equipment, reduce the UPS sensitivity. BATTERY CHARGE AND BATTERY LOAD LEDS FLASH SIMULTANEOUSLY UPS has shutdown. Check that the room temperature is within the specified limits for opera- The internal temperature of the tion. UPS has exceeded the allowable Check that the UPS is properly installed allowing for adequate ventilathreshold for safe operation. tion. Allow the UPS to cool down. Restart the UPS. If the problem continues contact APC at, DIAGNOSTIC UTILITY VOLTAGE FEATURE Utility Voltage The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power. Press and hold the button to view the utility voltage bar graph display. After a few seconds the five-LED, Battery Charge, , display on the right of the front panel shows the utility input voltage. Refer to the figure at left for the voltage reading (values are not listed on the UPS). The display indicates the voltage is between the displayed value on the list and the next higher value. Three LEDs light, indicating utility voltage within the normal ...
