Safety instructions:
- The installation must be equipped with a device that ensures omnipolar disconnection. A 10A circuit breaker is recommended.
- Do not connect the main network voltage or other external voltages to the KNX data bus or to the additional output.
- Connecting an external voltage may endanger the electrical safety of the entire KNX system.
- Always check during installation that there is sufficient insulation between the conductors of the 230V main voltage and the conductors of the Bus and its extensions.
- Do not cover the ventilation grilles to prevent the temperature acceptable to the device from being exceeded.
- Caution! Once the device has been installed, it must not be accessible from the outside.
- The electrical equipment must only be installed by qualified electricians and in accordance with accident prevention regulations.
- To prevent electrical accidents, before working on the unit, disconnect the main power supply with the circuit breaker located upstream of the unit.
- Failure to follow the installation instructions may cause damage to the installation.
