User manual APC SMART-UPS 2200VA LCD 230V

[. . . ] Placement Rear Views Voltage Sensitivity 990-7016B, Revision 3 The UPS detects line voltage distortions such as spikes, notches, dips, and swells, as well as distortions caused by operation with inexpensive fuel-powered generators. By default, the UPS reacts to distortions by transferring to on-battery operation to protect the loads. Where power quality is poor, the UPS may frequently transfer to on-battery operation. If the loads can operate normally under such conditions, battery capacity and service life may be conserved by reducing the sensitivity of the UPS. [. . . ] If the replace battery LED is still on, replace the battery using the Replacing the Battery procedure. SmartTrim The SmartTrim LED comes on to indicate that the UPS is compensating for a high voltage. SmartBoost The SmartBoost LED comes on to indicate that the UPS is compensating for a low voltage. When the UPS is operating on-battery and the energy reserve of the battery runs low, the UPS beeps continuously until the UPS shuts down from battery exhaustion or returns to on-line operation. Overload When loads exceed the UPS's capacity, the overload LED illuminates, the UPS emits a sustained tone, and the input circuit breaker may trip (the resettable center plunger of the circuit breaker pops out). The alarm remains on until the overload is removed. Disconnect nonessential load equipment from the UPS to eliminate the overload. If there is AC power and the circuit breaker does not trip during overload, the loads are still powered. If the circuit breaker trips and the UPS attempts to go on-battery, the output AC will shut down. Cold Start When the UPS is off and there is no utility power, it is possible to cold start the UPS to power the loads from the UPS's battery. Note: Cold start is not a normal condition. · 100% 80% 60% 40% 20% Battery Charge Bar Graph The 5-LED display on the right of the front panel shows the present charge of the UPS's battery as a percentage of the battery's capacity. For example, if three LEDs are lit, the load is drawing between 50% and 67% of the UPS's capacity. If all five LEDs light, thoroughly test your complete system to make sure that the UPS will not become overloaded. Storage Storage Conditions Store the UPS covered and upright in a cool, dry location, with its battery fully charged. Before storing, charge the UPS for at least 4 hours. Disconnect any cables connected to the computer interface port to avoid unnecessarily draining the battery. Extended storage · · At -15 to +30 °C (+5 to +86 °F), charge the UPS's battery every 6 months. At +30 to +45 °C (+86 to +113 °F), charge the UPS's battery every 3 months. Replacing the Battery This UPS has an easy to replace hot-swappable battery. Battery replacement is a safe procedure, isolated from electrical hazards. You may leave the UPS and loads on for the following procedure. See your dealer or call the number in this manual for information on replacement battery kits. Note: Please read the cautions in the APC Safety Guide. Once the battery is disconnected, the loads are not protected from power outages. [. . . ] Unhook the bottom of the cover from the chassis and lift it upward to expose the battery door. Be careful not to strain the ribbon cable. Do not touch the exposed printed circuit board. Fold the front cover on top of the UPS as shown. [. . . ]
