SAFETY INSTRUCTIONS
Do not connect Mains Voltage (230 V) or any other external voltages to any point of the BUS. Connecting an external
voltage might put the entire KNX system at
risk.
Make sure during the installation that there is always sufficient insulation between the mains voltage 230V and the bus or
the extension inputs.
Once the device is installed, the terminals should not be accessible.

1.
Extract the battery holder from the upper
side of KCI. It is recommended to have the
bus KNX connected during this process to
prevent S0 pulses loss.
2.
Place the batteries in the battery holder (respecting the polarity
shown) and insert it as indicated in the figure.
