Product Usage Instructions
- Mount the device onto the DIN rail.
- Connect the KNX system using the provided connections.
- Connect the mains voltage to the power supply unit.
- Ensure that the green operating display is lit, indicating that the power supply is ready for operation.
- If the red LED is on, it means the output current is too high. Check the connected devices and reduce the power consumption until it is less than the power supply unit’s nominal current.
- If the red LED is flashing, there is a short circuit in the bus line. Switch off the power supply, eliminate the cause of the short circuit, and then switch it back on. Press the reset key once to reset the bus line.
- When the power supply is reset (Reset LED is lit up), the bus line is released for about 20 seconds. All other devices connected to the same line will also be reset.

For your safety
Danger
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Safe electrical installation must be carried out only by skilled
professionals. Skilled professionals must prove profound knowledge in the
following areas:
- Connecting to installation networks
- Connecting several electrical devices
- Laying electric cables
- Connecting and establishing KNX networks
- Safety standards, local wiring rules and regulations
Failure to follow these instructions will result in death or serious injury.
Caution
The device may be damaged!
All devices that are mounted next to the power supply unit must at least be
equipped with basic insulation!
Failure to follow these instruction can result in equipment damage.
Getting to know the power supply
The KNX power supply REG-K (referred to below as the Power supply) provides
bus line devices with power. At least one power supply is required per bus
line. The integrated choke isolates the data telegram from the power supply.
The power supply provides a stabilised safety extra-low voltage (SELV) of DC
30 V. It is short-circuit-proof, and features a voltage and current limiter.
Excessively high output currents are indicated by a red LED (I>Imax). The bus
devices on the connected line can be reset using the reset key on the power
supply. This status displayed via the red reset LED. The green LED (RUN)
indicates that the power supply is ready for operation. The max. cable length
between the power supply and the furthest bus device is 350 m. The power
supply is intended for installation on the DIN rail TH 35 according to EN
60715. A data rail is not required.
Connections, displays and operating elements
- A Reset key with integrated reset LED
- B Green LED: Operating display (RUN)
- C Red LED: Overcurrent display (l>lmax)
- D Bus connection (with cover)
Installing and connecting the power supply unit
WARNING
Risk of death from electric shock. The device can become damaged.
Safety clearance must be guaranteed in accordance with IEC 60664–1. There must
be at least 4 mm between the individual cores of the 230 V supply cable and
the KNX line A.
Danger
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Make sure that live lines do not come into contact with unused terminals (e.g.
by using cable separating raceways). Failure to follow these instructions will
result in death or serious injury.
- Place the device onto the DIN rail.
- Connect KNX
- Connect the mains voltage.
The green operating display lights up when the power supply is ready for operation.
Meaning of the LEDs
The overcurrent display (I >Imax) lights up.
The operating display (RUN) lights up.
The output current is too high. Remove devices from the line until the total
power consumption of the remaining devices is less than the power supply
unit’s nominal current.
Caution
- The device may be damaged!
- No other power supply should be connected up to the power supply unit REG-K/640 mA within one KNX line!
- Failure to follow these instruction can result in equipment damage.
The overcurrent display (I>Imax) lights up.
The operating display (RUN) does not light up.
Short circuit in the bus line. Switch off the mains voltage for at least 30
seconds. Eliminate the cause of the short circuit. Then switch the power
supply back on and press the reset key once.
When the power supply is reset (Reset LED is lit up) the bus line is released
for about 20 seconds.
All other devices that are connected to the same line are then also reset.
