# Etrel AC Charger

#### 1. Startup and Connection

Once all wiring is complete, you can 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.

{% hint style="info" %}
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.
{% endhint %}

#### 2. Settings & Modbus

Log in and go to the configuration page.

* Firewall: Ensure Port 502 and Subnet 255.255.255.0 are open.

#### 3. Restart the Charger

Important: After changing the network or Modbus settings, you must restart the charging station to ensure the new configuration takes effect.

* Action: Reboot the charger via the web interface or by power cycling the unit.

* Wait: Wait until the LED above the display turns solid green again.

#### 4. Safety Check & Completion

* Protection: Verify that the Residual Current Device (RCD) and Miniature Circuit Breaker (MCB) are active.

{% hint style="info" %}
*Note:* For Etrel INCH models without built-in protection, these must be installed externally in the main distribution board.
{% endhint %}

* LED Status Check (above Display):
  * &#x20;Green: Available.
  * &#x20;Flashing Blue: Charging in progress.
  * &#x20;Red: Error (inspection required).
