- For telephone/fax or network surge protection, connect the incoming line to the "IN" port and your device to the "OUT" port using appropriate cables.
- (Optional) Connect the USB cable from the UPS to your computer's USB port to enable power management software features (software not included, typically downloadable from manufacturer's website).
5. Operation
5.1 Turning the UPS On/Off
- To Turn On: Press and hold the power button for approximately 2 seconds. The UPS will beep, and the green LED will illuminate, indicating it is operating in AC line mode.
- To Turn Off: Press and hold the power button for approximately 2 seconds. The UPS will beep, and the green LED will turn off.
5.2 LED Indicators and Audible Alarms
| Indicator | Status | Description |
|---|---|---|
| Green LED | Solid On | UPS is operating on AC utility power (Line Mode). |
| Yellow LED | Flashing | UPS is operating on battery power (Battery Mode). Audible alarm will sound. |
| Red LED | Solid On | Indicates an overload condition or a fault. |
| Audible Alarm | Beeping (e.g., every 10 seconds) | UPS is operating on battery power. |
| Audible Alarm | Continuous Beep | Low battery warning or overload condition. |
5.3 Power Management
The Smartbitt SBNB1000 provides automatic voltage regulation (AVR) to correct minor power fluctuations without switching to battery power, thus preserving battery life. During a power outage or significant voltage drop, the UPS will automatically switch to battery power, indicated by the yellow LED and an audible alarm.
When the UPS is operating on battery power, save your work and shut down your computer properly to prevent data loss. The battery backup time is approximately 35 minutes at full load (500W). Actual backup time may vary depending on the connected load.
6. Maintenance
6.1 Battery Care
- The UPS contains a sealed lead-acid battery. This battery is not user-serviceable.
- To maximize battery life, keep the UPS connected to an AC outlet at all times to ensure the battery remains charged.
- Avoid storing the UPS in extreme temperatures.
- If the UPS is stored for an extended period, recharge the battery every three months to prevent permanent damage.
- Battery replacement should only be performed by qualified service personnel.
6.2 Cleaning
Use a soft, dry cloth to clean the exterior of the UPS. Do not use liquid or aerosol cleaners. Ensure the UPS is turned off and unplugged from the wall outlet before cleaning.
7. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| UPS does not turn on. | No AC input power. Battery discharged. | Ensure the power cord is securely connected to a live wall outlet. Allow the UPS to charge for at least 4 hours. |
| UPS beeps continuously, Red LED is on. | Overload condition. | Disconnect non-essential equipment from the UPS outlets. Ensure total connected load does not exceed 500W. |
