Installation diagrams

The device can be installed by wiring the outputs either

with a separate COM pole or with a common COM pole.

Therefore the following schemes can be created:

1. Outputs with separate COM pole connection

Dimmer KNX 90-230V~ 50/60 Hz

Out: 4x 200W

2. Outputs with common COM pole connection

The terminals indicated by the COM label can be used as

a common terminal for the loads.

Warning! The input N terminals must never be con-

nected to the COM outputs.

Warning! In configuration 2, the internal fuse on

the load, which implements overcurrent protection,

does not trip.

The electronic short circuit protection remains fun-

ctional.

Commissioning

For commissioning the device the following activities are

required:

• make the electrical connections as described above;

• turn on the bus power supply;

• switch the device operation to the programming mode

by pressing the programming pushbutton (5) loca-

ted on the front side of the housing. In this operating

mode, the programming LED is turned on;

• download into the device the physical address and the

configuration with the ETS

At the end of the download the operation of the device

automatically returns to normal mode; in this mode the

programming LED is turned off. Now the bus device is

programmed and ready for use.

Note. The configuration and commissioning of KNX

devices require specialized skills. To acquire these

skills, you should attend the workshops at KNX cer-

tified training centers.

Device reset

To reset the device, remove the power from the KNX bus;

then press the programming button and, keeping it pres-

sed, restore power to the KNX bus: if, after approximately

10 s, the programming LED flashes quickly, it means that

the reset has been carried out. At this point it is necessary

to re-address and configure the device via ETS.

Warning! The reset operation brings back the devi-

ce to its factory delivery state. The addressing and

value of the parameters set during configuration are

lost.
