Problem and possible cause solutions UPS cannot start button is not pressed ON. Press the ON button to supply power to the UPS and equipment. UPS not connected to the mains power UPS and power supply connection by cable or connector is connected securely. UPS input circuit breaker tripped to reduce the load on the UPS, disconnect the equipment load is connected, and into the circuit breaker button to reset the circuit breaker (on back of UPS). Check whether the input air and received on a protector, and if so, remove the leakage after the test is also insured trip. Mains voltage too low or zero check the AC power supply, a lamp connected to the mains, if the lighting is Dim or Flash, you need to check the mains voltage. The external battery is connected properly check the battery connector is securely connected. Despite normal input voltage, but UPS battery UPS input circuit breaker tripped. Reduce the load on the UPS, disconnect the equipment load is connected, and into the circuit breaker button to reset the circuit breaker (on back of UPS). Check whether the input air and received on a protector, and if so, remove the leakage after the test is also insured trip. Line voltage is too high, too low or distorted. Use small power petrol or diesel generator will make UPS input voltage serious distortion of the UPS connected to other circuit on another power outlet, power back up to see whether the normal UPS while power Analyzer or oscilloscope to test whether the input voltage and frequency. Side lamps lit, overload lights and fault lights will too many devices connected to the UPS disconnect all non-essential device. Press the ON button to restart to see if it is normal. External dynamic overload to wait until the overload is gone. You may need to press the ON button to restart the UPS. Fault lights, overload, next to the street lamp light, no light overload disconnect all non-essential equipment. Press the OFF button, and then press the ON button to restore the power supply. Fault lights, no bright lights overload UPS internal UPS fault must not attempt to use. Turn off the UPS and immediately for repair. Replace battery light is not enough battery power to check the battery status and the battery for at least 24 hours in restorative charging. If the problem persists after recharging, replace the battery. The battery is connected incorrectly check that all the battery connector is securely connected and connectors oxidation phenomena exist. UPS occasionally alert UPS up and running without the need to take action. UPS is protecting the connected device. UPS does not provide expected backup time may be due to recently had a power outage or battery life, battery power low on battery. Extended power battery recharging after response. If the battery regularly work or frequently at high temperatures, will speed up the battery capacity of consumption. If the battery has been used 3 years to 5 years, also need to consider replacing the battery. Front panel LEDs blinking UPS in order to be remotely shut down or be a graceful shutdown of the APC management software. No need to take action. When power is restored, the UPS will restart automatically or by pressing ON the button start UPS.
