Installation and wiring
General description
The wall switch is slid onto the bus coupling unit (BTM)
together with its design frame (DELTA style).
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 design 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).
