4. Setup & Installation
Follow these steps for proper installation of your GIANDEL 1500 Watt Pure Sine Wave Power Inverter.
- Mounting the Inverter: Choose a dry, well-ventilated location. Ensure adequate clearance around the inverter for proper airflow to the cooling fans. The inverter can be mounted horizontally or vertically.
- Connecting to Battery:
- Ensure the inverter is turned OFF before making any connections.
- Connect the included red cable to the positive (+) terminal of the inverter and the positive (+) terminal of your 12V battery.
- Connect the included black cable to the negative (-) terminal of the inverter and the negative (-) terminal of your 12V battery.
- Tighten all connections securely to prevent loose contacts, which can cause overheating.
- Grounding: Connect the grounding wire from the inverter's grounding screw to a proper earth ground (e.g., vehicle chassis, ground rod).
