5. Setup

Follow these steps to set up your POXURIO Sump Pump Battery Backup System:

1. Prepare the Battery: Ensure you have a fully charged 12V deep cycle battery (e.g., marine battery, RV battery). This system does not include a battery.
2. Connect Battery Cables:
   • Connect the RED battery cable to the POSITIVE (+) terminal of the battery.
   • Connect the other end of the RED battery cable to the POSITIVE (+) terminal on the back of the backup system unit.
   • Connect the BLACK battery cable to the NEGATIVE (-) terminal of the battery.
   • Connect the other end of the BLACK battery cable to the NEGATIVE (-) terminal on the back of the backup system unit.
   • Ensure all connections are tight and secure.
3. Connect AC Power: Plug the provided AC power cord into the "Grid Input" socket on the front panel of the unit. Then, plug the other end of the AC power cord into a standard 120V AC wall outlet.
4. Connect Sump Pump(s): Plug your sump pump(s) directly into the "AC Output 120V" sockets on the front panel of the backup system. Ensure the total wattage of connected devices does not exceed 2000W.
5. Initial Power On: Once all connections are secure, flip the "Power" switch on the front panel to the "ON" position. The LCD display should illuminate.

6. Operation

Operating the POXURIO Sump Pump Battery Backup System is straightforward:

• Power On/Off: Use the "Power" switch on the front panel to turn the unit ON or OFF.
• LCD Display Monitoring: The integrated LCD display provides real-time operational status:
  • Voltage: Displays the current output voltage (120 VAC).
  • Frequency: Shows the output frequency (60 Hz).
  • Working Temperature: Indicates the internal temperature of the unit.
  • Battery Level: Shows the remaining charge of the connected battery.
  • Load Power: Displays the current power consumption of connected devices in watts.
• Automatic Switchover: When the main AC power supply is interrupted (e.g., during a power outage), the system will automatically and seamlessly switch to battery power to keep your sump pump running.
• Automatic Charging: Once the main AC power is restored, the system will automatically switch back to AC power and begin recharging the connected battery using its 20A fast charger. The "Working/Charge" indicator light will show the charging status.
• Breaker: The unit includes a resettable breaker. If an overload occurs, the breaker may trip to protect the system. Reduce the load and press the breaker button to reset.
