6. Setup and Installation

Follow these steps for proper installation of your inverter.

1. Choose a Location: Select a cool, dry, and well-ventilated area for the inverter. Avoid direct sunlight, heat sources, and moisture. Ensure there is enough space around the inverter for air circulation.
2. Mounting: The inverter has mounting brackets for secure installation. Use appropriate screws and anchors for your mounting surface.
3. Grounding the Inverter:
   • Locate the grounding terminal on the inverter chassis.
   • Connect one end of the provided grounding wire to this terminal.
   • Connect the other end of the grounding wire to a proper earth ground (e.g., vehicle chassis, ground rod, or electrical system ground).
4. Connecting to the Battery:

   WARNING: Ensure the inverter is OFF before connecting to the battery. Connect positive to positive and negative to negative. Reverse polarity will damage the inverter.

   • Connect the RED battery cable to the Positive (+) terminal of the inverter.
   • Connect the other end of the RED cable to the Positive (+) terminal of your 12V DC battery.
   • Connect the BLACK battery cable to the Negative (-) terminal of the inverter.
   • Connect the other end of the BLACK cable to the Negative (-) terminal of your 12V DC battery.
   • Ensure all connections are tight and secure to prevent loose connections and arcing.
