SAFETY INSTRUCTIONS
Installation should only be performed by qualified electricians following applicable regulations on preventing accidents, as
required by law.
Do not connect Mains Voltage (230VAC) 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 230VAC and the
bus or the extension inputs.
Once the device is installed, the terminals should not be accessible.
The WEEE logo means that this device contains electronic parts and it must be discarded properly following the

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.
