- Surge Protected Outlets Only: (e.g., 4 outlets) Protect against surges but do not provide battery backup.
- USB Port: For connecting to a computer for monitoring and management software.
- RJ45 In/Out Ports: For telephone/network line surge protection.
5. Setup
Follow these steps for initial setup of your Smartbitt UPS:
- Placement: Place the UPS in a cool, dry, and well-ventilated indoor area. Avoid direct sunlight and heat sources. Ensure there is adequate space around the unit for proper airflow.
- Initial Charge: Connect the UPS power cord to a grounded wall outlet. Allow the UPS to charge for at least 8 hours before connecting any devices. This ensures the battery is fully charged and ready to provide maximum backup time.
- Connect Devices:
- Connect critical devices (e.g., computer, monitor, modem) to the Battery Backup & Surge Protected Outlets. These outlets will provide power during an outage.
- Connect non-critical devices (e.g., printer, scanner) to the Surge Protected Outlets Only. These outlets will protect against surges but will not provide power during an outage.
- USB Connection (Optional): Connect the supplied USB cable from the UPS USB port to your computer's USB port. Install the monitoring software (if provided) to enable advanced features like automatic shutdown and status monitoring.
- Telephone/Network Line Protection (Optional): Connect your telephone or network cable to the RJ45 'IN' port on the UPS, then connect another cable from the 'OUT' port to your device (e.g., modem, phone).
6. Operating Instructions
6.1 Powering On/Off
- To Power On: Press and hold the power button for approximately 2 seconds until you hear a beep and the indicator lights illuminate.
- To Power Off: Press and hold the power button for approximately 2 seconds until you hear a beep and the indicator lights turn off.
6.2 LED Indicators
The LED indicators on the front panel provide information about the UPS status:
- Green LED (On): UPS is operating normally, providing AC power to connected devices.
- Yellow LED (Flashing): UPS is operating on battery power (during an outage).
- Red LED (On/Flashing): Indicates a fault, overload, or low battery condition. Refer to the Troubleshooting section.
6.3 Battery Backup Duration
The Smartbitt UPS 1800VA can maintain power to your equipment for up to 50 minutes, depending on the load connected. For example, a typical PC setup with two monitors (approx. 400W PC + 100W monitors) may provide several minutes of backup, allowing ample time to save work and shut down systems properly.
7. Maintenance
Proper maintenance ensures the longevity and optimal performance of your UPS.
- Battery Care: To maximize battery life, keep the UPS connected to an AC outlet at all times. If the UPS is stored for an extended period, recharge the battery every three months for at least 8 hours.
- Cleaning: Disconnect the UPS from the wall outlet and all connected devices before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners.
- Battery Replacement: The battery in this UPS is not user-replaceable. If the battery needs replacement (e.g., after several years of use, or if the UPS fails to hold a charge), contact Smartbitt customer support or a qualified service technician.
