Setup and Connection
The VECTOR PI500V Power Inverter offers two primary methods for connection to a 12V DC power source, depending on your power requirements.
Method 1: Direct Connection to Vehicle Battery (500W Output)
This method provides the full 500 watts of power and is suitable for higher-wattage appliances.
- Ensure your vehicle is turned off and the inverter's power switch is in the OFF position.
- Connect the red (positive) battery clamp to the positive (+) terminal of your vehicle's 12V battery.
- Connect the black (negative) battery clamp to the negative (-) terminal of your vehicle's 12V battery.
- Securely attach the ring terminals of the battery clamps to the corresponding terminal posts on the inverter (red to red, black to black).
- Verify all connections are tight and secure before proceeding.
Method 2: 12V DC Accessory Outlet Connection (120W Output)
This method provides up to 120 watts of power and is convenient for in-cabin use with lower-wattage devices.
- Ensure your vehicle is turned off and the inverter's power switch is in the OFF position.
- Insert the 12V DC plug into your vehicle's accessory outlet (cigarette lighter socket).
- Ensure the connection is firm.

Operating Instructions
Follow these steps to operate your VECTOR PI500V Power Inverter safely and effectively:
- After connecting the inverter to a power source using one of the methods described above, switch the inverter's ON/OFF button to the ON position. The green LED indicator will illuminate to confirm the unit is powered and operating normally.
- Plug your 120V AC appliances into the dual AC outlets or your USB devices into the dual USB charging ports.
- Monitor the LED indicator for status. A steady green light indicates normal operation. If the light flashes or changes color, refer to the Troubleshooting section.
- When finished, switch the inverter's ON/OFF button to the OFF position and disconnect it from the power source.
Powering Devices
The inverter provides 500 watts of continuous power when connected via battery clamps and 120 watts when connected via the 12V DC plug. Always ensure the total wattage of all connected devices does not exceed the inverter's capacity for the chosen connection method to prevent overload.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your power inverter:
- Cleaning: Keep the inverter clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure proper ventilation around the unit. Do not block the cooling fan or air vents, as this can lead to overheating.
- Connection Checks: Regularly check all electrical connections (battery clamps, 12V DC plug, and inverter terminals) for tightness and signs of corrosion. Loose connections can cause overheating, arcing, or poor performance.
- Storage: Store the inverter in a cool, dry place away from direct sunlight, moisture, and extreme temperatures when not in use.
Troubleshooting
If the inverter is not functioning as expected, consult the following troubleshooting guide:
- No Power/LED Off:
- Check the power source connection (battery clamps or 12V DC plug). Ensure they are securely attached.
- Verify the vehicle's battery has sufficient charge (typically above 12V).
- Ensure the inverter's ON/OFF switch is in the ON position.
- LED Flashing/Fault Indication:
- This usually indicates an overload, high/low input voltage, or thermal shutdown.
- Disconnect all devices from the inverter, turn it off, and then back on.
- Reduce the total wattage of connected devices if an overload is suspected.
- Check the vehicle's battery voltage if low/high voltage is indicated.
- Allow the unit to cool down if thermal shutdown occurs (ensure vents are clear).
- Device Not Charging/Powering:
- Ensure the device is properly plugged into the inverter's AC outlet or USB port.
- Check the device's power requirements against the inverter's capacity.
- Some sensitive electronic devices may require a pure sine wave inverter for optimal performance.
- Excessive Fan Noise:
- The built-in cooling fan operates automatically when the unit heats up. This is normal.
- If the noise is unusually loud or persistent, ensure the vents are clear and the unit is not overloaded.
