- ‧KNX bus need to be connected when using PUSH Dimming 

- ‧The detailed function of PUSH dimming, please refer to the database. 

- ‧The maximum length of the cable between the push button and driver is 20 meters. 

- ‧The mechanical push button can be connected only between the PUSH terminal, as displayed in the diagram, and AC/L (in brown or black); It will not function properly if it is connected to AC/N. 

- ‧In case the PUSH dimming is set locally, up to 10 drivers can perform the PUSH dimming at the same time when utilizing one common push button. ‧In case the PUSH dimming is set independently via ETS, the number of drivers is done through group address and determined by the ETS project designer.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
