5. Impostazione
Follow these steps for proper installation of your inverter.
5.1. Montaggio dell'inverter
Choose a dry, well-ventilated location for mounting the inverter. Use the provided mounting screws and plastic anchors to secure the inverter firmly to a stable surface. Ensure there is sufficient space around the unit for airflow, especially around the cooling fans.
5.2. Collegamento alla batteria
- Assicurarsi che l'interruttore ON/OFF dell'inverter sia in posizione 'OFF'.
- Connect the red battery cable to the inverter's positive (+) terminal and then to the battery's positive (+) terminal.
- Connect the black battery cable to the inverter's negative (-) terminal and then to the battery's negative (-) terminal.
- Assicurarsi che tutti i collegamenti siano ben saldi e sicuri. Collegamenti allentati possono causare surriscaldamento e danni.
5.3. Grounding the Inverter
Connect the provided earth terminal cable to the inverter's earth terminal and then to a reliable ground point (e.g., vehicle chassis, earth rod). This is crucial for safety.
5.4. Collegamento del telecomando
Plug the remote control cable into the remote control port on the inverter. Mount the remote control unit in a convenient location using the provided screws and anchors. The 450cm cable allows for flexible placement, enabling remote monitoring and control of the inverter's status.
