1 Safety instructions

Electrical devices may be mounted and connected only by electrically skilled persons.

Serious injuries, fire or property damage are possible. Please read and follow the manual fully.

Danger of electric shock. During installation and cable routing, comply with the regulations and standards which apply for SELV circuits.

These instructions are an integral part of the product, and must remain with the end customer.

3 Function

System information

This device is a product of the KNX system and complies with the KNX directives. Detailed technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.

Intended use

– Supplying KNX devices with bus voltage
– Supplying devices with direct current
- Mounting on DIN rail according to EN 60715 in sub-distribution unit

Product characteristics

• Output with integrated inductance for supplying KNX bus lines
• DC 30 V output for supplying additional devices
  – Nominal current can be subdivided to outputs as desired
• Reset button
• Short-circuit proof

• Overvoltage proof

• No-load proof

• Suitable for operation in systems with emergency power supply
  – Potential-free signal contact for operating and diagnostic message
• Two identical voltage supplies can be connected in parallel (with the version 640 mA)

4 Operation

Acknowledging the diagnostic message

After detecting a overvoltage or a short circuit the LED and the signal contact signal the event until the message is acknowledged.

■ Press the Reset button for less than 0.5 seconds.

In normal operation, control of the voltage supply is not necessary. The button (8) is recessed and thus prevents that it is inadvertently actuated in operation.

Reset function and Reset button

When a bus segment is reset, the output voltage of the voltage supply is switched off. At the same time the bus line is short-circuited so that all connected bus devices are disconnected from the bus voltage.

Resetting the bus line for 20 seconds

■ Press the Reset button (8) between 2 ... 4 seconds.

The bus line is short-circuited for 20 seconds.

The LED Reset (7) flashes quickly.

After 20 seconds the bus voltage is switched on again and the LED Reset switches off.

Permanently resetting the bus line

■ Press the Reset button (8) for more than 4 seconds.

The bus line is short-circuited.

The LED Reset (7) flashes slowly.

Terminating the permanent reset

Prerequisite: The bus line is permanently reset, the LED Reset (7) flashes slowly.

■ Press the Reset button (8).

The bus voltage is switched on again and the LED Reset switches off.

5 Information for electrically skilled persons

DANGER!

Electric shock when live parts are touched.

Electric shocks can be fatal.

Before working on the device, disconnect all corresponding circuit breakers from the supply voltage, secure against being switched on again and check that there is no voltage!

5.1 Mounting and electrical connection

Mount device

Observe the temperature range. Ensure sufficient cooling.

■ Mount the device on DIN rail. The terminals for the mains connection (1) must be at the top.

Connecting the device to mains voltage and bus

L N PE L N DC 30 V BUS DC 30 V BUS

Figure 3: Wiring example – mains voltage and bus line

0,5 ... 4 mm² 0,5 ... 4 mm² 0,5 ... 2,5 mm²

Figure 4: Clampable conductor cross-section

■ Connect the mains voltage to the terminals L and N (1).
■ Connect the protective conductor PE to the terminal 12 .
■ Connect the KNX bus line to output Bus (6).
■ Install the cover to protect the bus connection against hazardous voltages in the connection area.

The total load of the outputs can be subdivided as desired. Do not exceed the total rated current.
Do not connect any other products to the bus output. This might influence the bus communication.
If required, an identical voltage supply can be connected in parallel for the device variant 640 mA.

Connecting the diagnostic analyser

The voltage supply signals overvoltage, overload, short circuit and KNX voltage failure using a floating contact (9). A monitoring device can detect the switching status and forward it for diagnostic purposes.

The signal output serves only for signalling purposes and may not be used as a load output.

A signal lamp, a signal relay or, e.g., a KNX binary input connected to a KNX bus line can be used as monitoring device.

■ Connect the signalling device according to the connection example (see figure 5).

L N PE max. 2 A L N

Figure 5: Application example – signal lamp for optical operating display

■ Connect the KNX binary input according to the connection example (see figure 6).

Figure 6: Application example – KNX binary input on main line for detecting and centrally signalling diagnostic messages

i Observe the wiring! Install the cables for the signal contact such that no loops are created. During operation loops can cause interference voltages to be coupled into.
The signal contact indicates a power failure on the KNX line. When voltage supplies are connected in parallel, the signaling contact opens only if both voltage supplies are faulty or switched off (e.g. due to failure of the mains voltage on both devices).

In this case too, the green operation LED will not extinguish until both power supplies are switched off.

Operation with emergency power systems

The voltage supply can be used in combination with centrally supplied emergency power systems. In this way, the function of the KNX system and the control of the most important functions can be ensured in emergency operation.

i Statutory and standard specifications for emergency power and emergency lighting systems vary from country to country. In any event, the user / technical planner must check whether the specific specifications are observed.

Cable lengths

For KNX line segments and power supplies the following rules apply:

• Bus line length per line segment: Max. 1000 m
• Bus line length between voltage supply and KNX bus subscriber: Max. 350 m
• Bus line length between two KNX bus subscribers: Max. 700 m
