Startup and connection
Once all wiring is complete, switch on the charger.
Wait for Green: The green LED flashes during startup. Wait until it turns solid green; the charger is now ready for use. This LED is located just above the charger display.
Open Web Interface: Connect your laptop to the same network as the charger. Enter the IP address (found on the sticker inside the maintenance door) into your browser.
Tip: Can't find the IP address? Press and hold the small reset button (inside the small door on the top right) until you hear a beep. This accesses the charging station settings. Navigate to the correct sub-menu on the screen to view the current IP address.
