The maximum length of the cable between the push button and driver is 20 meters.
The additive push button can be connected only between the PUSH terminal, as displayed in the diagram,
and AC/L (in brown or black); it will lead to short circuit if it is connected to AC/N.

7. Configuration and Commissioning
The application program(database) can be downloaded via Online Catalogs from ETS
or via http://www.meanwell.com/productCatalog.aspx
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.
