3. Setup Guide
- Unpack and Inspect: Carefully remove the UPS from its packaging. Inspect for any shipping damage.
- Battery Connection: The UPS battery may be disconnected for shipping. Refer to the quick start guide for specific instructions on connecting the internal battery. This usually involves rotating or pushing a battery connector into place.
- Placement: Place the UPS on a flat, stable surface away from direct sunlight, excessive heat, or moisture. Ensure adequate ventilation around the unit.
- Connect Equipment:
- Connect critical equipment (computer, monitor, modem, router) to the Battery Backup + Surge Protected outlets. These outlets provide power during outages.
- Connect non-critical equipment (printer, scanner, speakers) to the Surge Only Protected outlets. These outlets provide surge protection but no battery backup.
- For data line protection, connect your incoming Ethernet or Coaxial cable to the "In" port and then connect the "Out" port to your device (e.g., modem, TV).
- Connect to Wall Power: Plug the UPS power cord directly into a grounded 2-pole, 3-wire wall receptacle. Avoid using extension cords or surge strips.
- Initial Charge: Allow the UPS to charge for at least 24 hours before connecting any critical equipment or expecting full runtime. The battery will charge whether the UPS is turned on or off, as long as it is connected to wall power.
- Install Software (Optional but Recommended): Download and install APC PowerChute Personal Edition software from the APC website. Connect the UPS to your computer using the provided USB cable. This software enables automatic shutdown of your computer during extended power outages and provides advanced power management features.

4. Operating Instructions
4.1 Powering On/Off
- To Turn On: Press the Power button on the front panel. The LCD display will illuminate, and the UPS will perform a self-test.
- To Turn Off: Press and hold the Power button until the display turns off.
4.2 Understanding the LCD Display
The LCD display provides real-time information about the UPS status. Common indicators include:
- Load Indicator: Shows the percentage of connected load.
- Battery Charge Indicator: Displays the current battery charge level.
- Estimated Runtime: Indicates the approximate time the UPS can power connected equipment during an outage.
- Input/Output Voltage: Shows the incoming utility voltage and the voltage being supplied by the UPS.
- Overload/Fault Indicators: Alerts to potential issues with connected equipment or the UPS itself.
Use the display navigation buttons (if present) to cycle through different information screens.
4.3 Battery Backup Operation
During a power outage, the UPS will automatically switch to battery power, providing continuous power to connected equipment on the battery backup outlets. An audible alarm may sound to indicate battery operation. The LCD will show the remaining battery runtime.
If the outage is prolonged, the PowerChute software will initiate a graceful shutdown of your computer to prevent data loss.
4.4 USB Charging
The front-panel USB-A and USB-C ports provide 5V, 3A power for charging mobile devices. These ports are active when the UPS is connected to utility power or operating on battery power.

5. Maintenance
5.1 Battery Replacement
The internal battery typically lasts 3-5 years under normal operating conditions. Factors like frequent power outages and high temperatures can reduce battery life. When the battery needs replacement, the UPS will usually indicate this via an alarm or an LCD message.
Caution: Battery replacement should only be performed by qualified service personnel or by following the specific instructions provided by APC. Always disconnect the UPS from wall power before attempting battery replacement.
5.2 Cleaning
Clean the exterior of the UPS with a soft, dry cloth. Do not use liquid cleaners or aerosol cleaners. Ensure ventilation openings are free from dust and debris to maintain proper airflow.
5.3 Environmental Considerations
Operate the UPS within its specified temperature and humidity ranges. Avoid placing it near heat sources or in areas with high moisture. Proper environmental conditions contribute to the longevity and performance of the unit.
6. Troubleshooting
