General description The wall switch is slid onto the bus coupling unit (BTM) together with its design frame (DELTA style). The bus coupling unit (BTM) is mounted and installed in the in-wall box (see mounting instruc- tions for bus coupling unit (BTM) UP 117). Bus coupling unit (BTM) and the design frame “DELTA style” are not included and therefore have to be ordered separately (see current catalog).Mounting − Slip the wall switch's main module (F5) together with the de- sign frame (F3) onto the bus coupling unit (BTM) (F1) and firmly press them together. The electrical connection between the wall switch and the bus coupling unit (BTM) is established via a Bus Transceiver Interface (BTI) (F2 and F4).
