5. Setup Instructions
Follow these steps to set up your MFUZOP 1500W Pure Sine Wave Inverter:
- Choose a Location: Select a dry, well-ventilated area for the inverter. Ensure it is away from direct sunlight, heat sources, and moisture. The inverter comes with a safety cushioning base for stable placement.
- Prepare the Battery: Ensure your 12V battery is fully charged and in good condition.
- Connect Battery Cables:
- Connect the red battery cable to the positive (+) terminal of the inverter.
- Connect the other end of the red battery cable to the positive (+) terminal of the 12V battery.
- Connect the black battery cable to the negative (-) terminal of the inverter.
- Connect the other end of the black battery cable to the negative (-) terminal of the 12V battery.
- Ensure all connections are tight and secure to prevent arcing and overheating.
- Grounding: Connect a grounding wire (not included) from the inverter's ground terminal to a suitable earth ground point (e.g., vehicle chassis, ground rod).
- Remote Control (Optional): If using the wired remote control, plug it into the "REMOTE" port on the front panel.
- Initial Power On: Once all connections are secure, switch the AC Output ON/OFF switch to the "ON" position. The LCD display should illuminate, showing input voltage.
