Programming button: short press to set programming mode. If this button is held while plugging the device into the KNX bus, it enters the safe mode.
Programming LED: programming mode indicator (red). When the device enters the safe mode, it blinks (red) every half second. During the start-up
(reset or after KNX bus failure) and if the device is not in safe mode, it emits a red flash.
Test button: if this button is held for more than 3 seconds, the device enters the test mode.
Test LED: it indicates which channel (red=channel 1/R, green=channel 2/G, blue=channel 3/B) is being tested during test mode. In addition, it shows
errors in the installation and/or parameterization (see section “test LED error identification”).

SAFETY INSTRUCTIONSANDADDITIONAL NOTES
•Installation should only be performed by qualified professionals according to the laws and regulations applicable in each country.
•Do not connect the mains voltage nor any other external voltage to any point of the KNX bus; it would represent a risk for the entire
KNX system. The facility must have enough insulation between the mains (or auxiliary) voltage and the KNX bus or the wires of other
accessories, in case of being installed.
•The facility must be equipped with a device that ensures the omnipolar sectioning. Installation of a 10 A mini-circuit-breaker is
recommended. To prevent accidents, it must remain open in case of manipulation of the device.
•Once the device is installed (in the panel or box), it must not be accessible from outside.
•Keep the device away from water (condensation over the device included) and do not cover it with clothes, paper or any other material
while in use.
•The WEEE logo means that this device contains electronic parts and it must be properly disposed of by following the instructions at

External power supply:
+ and - terminals of external power supply (
constant

It is recommended to use the closest external power
supply value to the load working voltage.
Assembly:
Screw mounting, 2 holes of
3.5 mm diameter. Screws not
included.
SEVERAL LOADS CONNECTED TO THE SAME OUTPUT
Power restriction: It is mandatory to fulfil the next restriction
regarding the power connected to one output channel:

OUTPUT CURRENT SELECTOR SWITCH
*it is mandatory that the output current chosen by ETS
parameter and the current selected with the switchmatch. On
the contrary, the load cannot be controlled and the test LED will
blink in white.
TEST LED ERROR IDENTIFICATION
