3. Before connecting to the power supply, read the installation instructions at:
   https://www.iceriver.io/tutorial/
4. The socket must be located close to the device and be easily accessible.
5. Use a stable voltage.
6. Before switching on, check that all cables are securely and correctly connected.
7. The device must not be connected directly to a mains electrical source, but through double or reinforced insulation (applicable to devices without a built-in power supply).
