Chapter 1 Introduction
KNX power supply produces and monitors KNX system voltage. There are two connection
terminal of the output, one for KNX bus supply and signal transmission, one for auxiliary power
supply, can provide 30V DC voltage with terminal device.The bus connection terminal has
integrated the reactor inside the power supply; if the auxiliary power supply terminal is connected
with an external reactor, it can also be used as the bus power supply terminal, and also with the
function of signal transmission.
The KNX power supply is an analog-to-digital installation equipment. In order to facilitate the
installation in the distribution box, according to the design of EN 60 715, it can be installed on a
35mm DIN rail. The device is connected with the screw post for electrical connection. The bus
connection is directly connected through the KNX connection terminal (red/ black). The auxiliary
power supply is also connected directly through the KNX connection terminal (yellow/ white), and
the input end is connected to the power supply voltage of 230V AC.
A reset of the power supply is triggered by pressing the reset button last for 22 seconds (it
does not include the time for button action).When bus supply terminal is disconnected from the
power supply,other devices on the bus will return to their initial state. If bus disconnect for a longer
period, the bus supply terminal must be removed from power supply.

Chapter 4 Normal Working Test
When power supply has been correctly installed, switch on the main power supply for the bus
power, and the green LED “ON”, the circuit level indicator LEDs up according to the range of loads,
and the other LEDs are switched off, that is, the device function correctly.
