2.3. Installation
The binary inputs are only suitable for connections to potential-free
contacts. When laying the connecting cables, take any necessary
precautions. Laying distances to low-voltage circuits to maintain safe
isolation. The binary inputs fulfil Safety Extra Low Voltage (SELV)
requirements.
Connection of clima BSK4-F
The module clima BSK4-F provides a TP/FT-10 transceiver to connect to a free-
topology LON network. The module is supplied by 24V AC or DC. The module

If dampers with two end-position switches are used, connect them
to two adjacent binary inputs. For the „top (open)“-position is the
lower sub-number (e.g. E1.1) input to be used and the position
„bottom (close)“-position is to be connected to the higher sub-
number (e.g. E1.2).
