Instruccions de configuració
- Trieu una ubicació: Select a dry, cool, and well-ventilated area for the inverter. Ensure there is sufficient space around the unit for airflow.
- Prepareu la bateria: Ensure your 12V battery is fully charged and in good condition.
- Connect DC Cables:
- Connecteu el VERMELL positive (+) battery cable to the VERMELL positive (+) terminal on the inverter.
- Connecteu el NEGRE negative (-) battery cable to the NEGRE negative (-) terminal on the inverter.
- Connecteu l'altre extrem del VERMELL positive (+) cable to the positive (+) terminal of your 12V battery.
- Connecteu l'altre extrem del NEGRE negative (-) cable to the negative (-) terminal of your 12V battery.
- Important: Assegureu-vos que totes les connexions estiguin ben ajustades i segures per evitar arcs elèctrics i sobreescalfament.
- Posada a terra: Connect a grounding wire from the inverter's grounding terminal to a proper earth ground (e.g., vehicle chassis, ground rod).
- Connect Remote Controller (Optional): Plug the remote controller cable into the designated port on the inverter.
- Comprovació inicial: Before turning on, double-check all connections.
Instruccions de funcionament
- Encès: Once all connections are secure, press the ON/OFF switch on the inverter or the remote controller to turn on the unit. The LCD display will illuminate, showing current status.
- Connecteu els dispositius de corrent altern: Plug your 110V/120V AC devices into the AC outlets on the inverter. For USB and Type-C charging, connect your devices to the respective ports.
