5. Setup and Installation
5.1 Choosing a Location
Select a location for the inverter that is:
- Dry and well-ventilated.
- Away from direct sunlight, heat sources, and flammable materials.
- Accessible for connections and maintenance.
- Securely mounted to prevent movement.
5.2 Connecting to a 12V DC Power Source
- Ensure the inverter is turned OFF.
- Connect the red battery cable to the positive (+) terminal of the inverter and then to the positive (+) terminal of your 12V battery.
- Connect the black battery cable to the negative (-) terminal of the inverter and then to the negative (-) terminal of your 12V battery.
- Ensure all connections are tight and secure to prevent loose connections and arcing.
- Connect the earth wire from the inverter's grounding terminal to a proper earth ground point.
5.3 Connecting the Remote Control
Plug the remote control cable into the designated remote port on the inverter. This allows for convenient power control from a distance.
