5. Setup and Installation
The Devolo dLAN pro 1200 DINrail is designed for permanent installation within an electrical distribution box or cabinet. Due to the nature of electrical work, this installation must be carried out by a certified electrician.
5.1. Installation Steps (for Qualified Electricians)
- Power Disconnection: Ensure the main power supply to the distribution box is completely disconnected and secured against accidental re-connection.
- Mounting: Mount the dLAN pro 1200 DINrail adapter onto a standard DIN rail within the electrical cabinet.
- Electrical Connection: Connect the adapter to the electrical network. The device supports three-phase connections (L1, L2, L3), Neutral (N), and Protective Earth (PE). Refer to the wiring diagram provided with the device for correct terminal assignments. It is crucial to connect the neutral conductor correctly.
- Network Connection: Connect an Ethernet cable from your router or network switch to the RJ45 port on the dLAN pro 1200 DINrail adapter.
- Power Restoration: Once all connections are secure and verified, restore power to the distribution box.

6. Operating Instructions
Once properly installed and powered, the Devolo dLAN pro 1200 DINrail adapter automatically establishes a Powerline network. Other Devolo Powerline adapters (e.g., dLAN 1200 series) can then be plugged into electrical outlets throughout the building to extend the network.
6.1. Status Indicators
The device features LED indicators to show its operational status:
- Power LED: Indicates if the device is powered on.
- Powerline LED: Indicates the status of the Powerline connection (e.g., green for good connection, amber for weaker connection, off for no connection).
- Ethernet LED: Indicates activity on the Ethernet port.
6.2. Network Configuration and Security
For advanced configuration, network monitoring, and security management (e.g., changing the network password, adding new adapters), use the Devolo Cockpit software. This software is typically provided on the installation CD or can be downloaded from the official Devolo website. The dLAN pro 1200 DINrail uses 128-bit AES encryption to secure your Powerline network.
7. Maintenance
The Devolo dLAN pro 1200 DINrail Powerline Adapter is designed for maintenance-free operation once installed. However, consider the following:
- Cleaning: If necessary, gently wipe the exterior of the device with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Firmware Updates: Periodically check the Devolo website for firmware updates. Updates can improve performance, add features, or address security vulnerabilities. Follow the instructions provided by Devolo for any firmware update process.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature range (0 °C to 55 °C) and free from excessive dust or moisture.
8. Troubleshooting
If you experience issues with your Devolo dLAN pro 1200 DINrail adapter, consider the following troubleshooting steps:
- No Power: Check the power supply to the distribution box and ensure the circuit breaker for the adapter is on. Verify the Power LED on the adapter is illuminated.
- No Powerline Connection: If the Powerline LED is off or amber, ensure all Powerline adapters in your network are properly plugged in and powered on. Electrical interference from other devices or long/poor quality wiring can affect performance.
- No Network Connection (Ethernet): Check the Ethernet cable connection between the adapter and your router/switch. Ensure the Ethernet LED on the adapter is active. Test the Ethernet cable with another device if possible.
- Slow Speed: Powerline performance can be affected by the quality and length of your electrical wiring, as well as other electrical devices. Try unplugging other high-power devices temporarily to see if performance improves. Ensure all adapters are from the same Powerline standard (e.g., dLAN 1200).
- Resetting the Device: If issues persist, a factory reset might be necessary. Refer to the Devolo Cockpit software or the full product manual for instructions on how to perform a reset. Note that resetting will erase all custom settings.
- Professional Assistance: For complex electrical or network issues, consult a qualified electrician or IT professional.
