2. Instruccions de seguretat
Please read and understand all safety instructions before installation and operation to prevent injury and damage to the controller or system components.
- Connecteu sempre la bateria al controlador de càrrega primer to allow the controller to recognize the system voltage.
- Ensure correct polarity when connecting components. Pay close attention to the "+" and "-" terminals. Incorrect wiring can cause damage.
- Do not insert fuses or turn on breakers during the initial installation process.
- Install the battery fuse as close to the battery as possible, ideally within 150mm.
- The VS AU series controller is a common positive ground device. Any positive connection of solar, load, or battery can be earth grounded if required.
- If an inverter or other load with a large starting current is necessary, connect it directly to the battery, not to the controller's load terminals.
- Assegureu-vos que hi hagi una ventilació adequada al voltant del controlador per evitar el sobreescalfament.
