In KNX version, the bus powers only the interface board, the main board is powered
by the secondary 31V–DC power supply (yellow and white).
Use a certified KNX power supply.
Most of KNX power supplies have a secondary 31V-DC power supply (yellow and
white cables and connector of the same colors).
In LON version use a power supply independent from the bus.
