Voltage Sensitivity The UPS detects and reacts to line voltage distortions by transferring to battery operation to protect the connected equipment. Where power quality is poor, the UPS may frequently transfer to battery operation. If the connected equipment can operate normally under such conditions, reduce the sensitivity setting to conserve battery capacity and service life. Brightly lit: UPS is set to high sensitivity. Dimly lit: UPS is set to medium sensitivity. Off: UPS is set to low sensitivity. To change the UPS sensitivity, press the voltage sensitivity button (rear panel). Use a pointed object (such as a pen) to do so. You can change the sensitivity level through PowerChute software. Alarm Control Enable Mute, Disable User can mute a present ongoing alarm or disable all existing alarms permanently. Shutdown Delay 90 seconds 0, 180, 270, 360, 450, 540, 630 seconds Sets the interval between the time when the UPS receives a shutdown command and actual shutdown. 8 NOTE: SETTINGS ARE MADE THROUGH SUPPLIED POWERCHUTE SOFTWARE OR OPTIONAL SMART SLOT ACCESSORY CARDS. FUNCTION FACTORY DEFAULT USER SELECTABLE CHOICES DESCRIPTION Low Battery Warning. Brightly lit: Low battery The low battery warning PowerChute interface software provides automatic, unattended shutdown when approximately two minutes (by default) of battery operated run time remains. warning interval is about two minutes. Dimly lit: Low battery warning interval is about five minutes. Off: Low battery warning interval is about eight minutes. Possible interval settings: 2, 5, 8, 11, 14, 17, 20, 23 minutes. beeps are continuous when two minutes of run time remain. To change the warning interval default setting, press the voltage sensitivity button (use a pointed object such as a pen to do so), while pressing and holding the button (front panel). Synchronized Turn-on 0 seconds 60, 120, 180, 240, 300, The UPS will wait the speci- Delay 360, 420 seconds fied time after the return of utility power before turn-on (to avoid branch circuit overload). High Transfer Point 230V models: 230V models: To avoid unnecessary battery 253VAC 257, 261, 265VAC usage, set the high transfer 120V models: 127VAC 120V models: 130, 133, 136VAC point higher if the utility voltage is chronically high and the connected equipment is 100V models: 100V models: known to work under this 108VAC 110, 112, 114VAC condition. Low Transfer Point 230V models: 230V models: Set the low transfer point 208VAC 196, 200, 204VAC lower if the utility voltage is 120V models: 106VAC 120V models: 97, 100, 103VAC chronically low and the connected equipment can tolerate this condition. 100V models: 100V models: 92VAC 86, 88, 90VAC Output Voltage 230V models: 230VAC 230V models: 220, 225, 240VAC 230V models ONLY: allows the user to select the on battery output voltage. 9 4: STORAGE, MAINTENANCE, AND TRANSPORTING Storage Store the UPS covered and positioned as for proper functioning, in a cool, dry location, with the batteries fully charged. At -15 to +30 °C (+5 to +86 °F), charge the UPS battery every six months. At +30 to +45 °C (+86 to +113 °F), charge the UPS battery every three months. Replacing the Battery Module This UPS has an easy to replace, hot-swappable battery module. Replacement is a safe procedure, isolated from electrical hazards. You may leave the UPS and connected equipment on for the following procedure. See your dealer or contact APC at the web site, for information on replacement battery modules. Once the battery is disconnected, the connected equipment is not protected from power outages. Be careful during the following steps-the battery module is heavy. Refer to Installing and Connecting the Battery and Attaching the Front Bezel, in this manual. Reverse the instructions for battery removal. Be sure to deliver the spent battery to a recycling facility or ship it to APC in the replacement battery packing material. Disconnecting the Battery for Transport Always DISCONNECT THE BATTERY before shipping in compliance with U.S. Department of Transportation (DOT) regulations. The battery may remain in the UPS; it does not have to be removed. 1. Shut down and disconnect any equipment attached to the UPS. 2. Shut down and disconnect the UPS from the power supply. 3. Unplug the battery connector. Refer to Mounting the UPS in a Rack, Steps 1 and 2 in this manual. For shipping instructions and to obtain appropriate packing materials contact APC at the web site, 10 5: TROUBLESHOOTING Use the chart below to solve minor Smart-UPS installation and operation problems. Refer to the APC web site, for assistance with complex UPS problems. PROBLEM AND POSSIBLE CAUSE SOLUTION UPS WILL NOT TURN ON Battery not connected properly. Check that the battery connector is fully engaged. button not pushed. UPS not connected to utility power supply. Very low or no utility voltage. Press the button once to power the UPS and the connected equipment. Check that th...
