- Locate the yellow battery connector on the rear panel of the UPS. This connector is typically disconnected for safe transport.
- Push the yellow battery connector firmly into its socket until it clicks into place. This activates the UPS battery circuits.
4.2. Conectando à energia
- Connect the UPS to a grounded 230V AC wall outlet using an appropriate IEC-320 C14 input power cable (not included).
- Ensure the connection is direct to the wall outlet. Do not use surge protectors or extension cords.
- Allow the UPS to charge for at least 10 hours before connecting critical equipment to ensure full battery runtime.
4.3. Conexão de Equipamentos
The BX1400UI features six IEC 320 C13 outlets for connecting your devices.
- Tomadas com bateria de reserva e proteção contra surtos: All six IEC-C13 outlets provide both battery backup and surge protection. Connect your computer, monitor, and other critical electronics to these outlets.
- Proteção da linha de dados: The rear panel includes RJ-11 ports labeled "DSL/Modem/Fax/Phone" for protecting your telephone or DSL line from surges. These ports are not suitable for Ethernet network connections.
- Interface USB: Connect a USB Type B cable (not included) from the UPS to your computer for communication and to enable shutdown software functionality.

5. Instruções de operação
5.1. Ligar / desligar
- Para ligar: Press and hold the power button on the front panel until you hear a short beep. The UPS will perform a self-test, and the 'On Line' LED will illuminate green.
- Para desligar: Pressione e mantenha pressionado o botão liga/desliga até que o UPS desligue.
5.2. Indicadores LED
The front panel features LED indicators to show the UPS status:
- On Line (Green LED): Indicates the UPS is operating on utility power and providing power to connected equipment.
- On Battery (Yellow LED): Indicates the UPS is operating on battery power during a power outage or brownout. A humming noise is normal during battery operation.
- Replace Battery (Red LED): Indicates the battery needs to be replaced.
- Overload (Red LED): Indicates that the connected equipment exceeds the UPS's capacity. Disconnect non-essential equipment immediately.
5.3. Vol automáticotage Regulamento (AVR)
O sistema UPS corrige automaticamente pequenas variações de tensão.tage fluctuations (sags and surges) without switching to battery power, thus preserving battery life. If voltage fluctuations exceed the AVR's correction range, the UPS will switch to battery power.
6. Principais características
- Tecnologia Line Interactive: Provides stable power by regulating voltage without constantly switching to battery.
- Vol Automáticotage Regulamento (AVR): Corrige pequenos volumestage flutuações sem usar a energia da bateria.
- Bateria de reserva: Supplies power to connected equipment during outage.
- Proteção contra surtos: Protects connected devices from damaging power surges and spikes.
- 6 IEC 320 C13 Outlets: Standard outlets for computer equipment.
- Interface USB: Enables communication with a computer for monitoring and controlled shutdown.
- Proteção da linha de dados: Safeguards telephone/DSL lines from surges.
7. Uso do software
The APC Back-UPS BX1400UI supports USB Human Interface Device (HID) class specifications, allowing it to be recognized by most operating systems without special drivers.
7.1. APC PowerChute Personal Edition (Windows)
For advanced monitoring and management on Windows systems, download the APC PowerChute Personal Edition software from the official APC website. Este software permite que você:
- Monitor UPS status, power consumption, and battery charge.
- Configure o desligamento automático do seu computador durante períodos prolongados de falta de energia.tage.
- Adjust UPS settings, such as alarm behavior (e.g., disable the beeper during battery operation).
- Perform self-tests to ensure proper UPS functionality.
7.2. Linux Support (apcupsd / NUT)
For Linux environments, the UPS can be managed using `apcupsd` or Network UPS Tools (NUT). These tools provide similar monitoring and shutdown capabilities. Refer to the documentation for `apcupsd` or NUT for configuration details, typically involving specifying `UPSCABLE usb` and `UPSTYPE usb` for `apcupsd`, or using the `usbhid-ups` driver for NUT.
8. Manutenção
8.1. Substituição da bateria
The APC Back-UPS BX1400UI uses two 12V 7.2Ah sealed lead-acid batteries. The recommended replacement battery pack is APC RBC113.
- During Warranty: If the unit is still under its 2-year warranty, battery replacement must be performed by Schneider Electric IT (SEIT) customer service. User-performed battery replacement during the warranty period will automatically void the warranty.
- After Warranty: After the warranty period, batteries can be replaced by the user. However, due to the presence of high voltage components even when disconnected, it is highly recommended that this operation be performed by specialized personnel. If you choose to replace the batteries yourself, exercise extreme caution.
- Procedimento encerradoview (for experienced users only): Disconnect the UPS from all power sources and connected equipment. Disconnect the yellow battery connector. Remove the rear panel screws, then the front panel (which is snap-fitted), and additional screws. Carefully access the battery compartment. Note the orientation and wiring of the existing batteries (taking photos is recommended) to ensure correct installation of the new batteries.
8.2. Reinicialização do disjuntor
In case of an overload, the UPS may trip its circuit breaker. To reset, disconnect some equipment from the UPS, then press the circuit breaker button located on the rear panel (refer to Figure 2).
9. Solução De Problemas
