KCI
KNX Consumption Interface
ZRX-KCI4SO Technical Documentation
FEATURES
4 channels for consumption counters (meters) with S0-pulse
outputs (UNE-EN 62053-31) *.
Registration of consumed electric power, cost and CO2emissions
that can be split in up to 4 time intervals.
Compliant with UNE-EN 62053-31 Class B.
Total data saving on KNX bus power failure.
KNX BCU integrated.
Size 90 x 60 x 35 mm (2 DIN units).
DIN rail unit assembly (EN 50022), with snap fit clamp.
CE directives compliant.
Programming button: short button press to set the programming mode. If this button is held while plugging the device into the KNX bus, it goes into
safe mode.
Programming LED: programming mode indicator (red). When the device goes into safe mode, it blinks (red) every half second.
LOW batt. LED: if this LED is blinking in red, replace the batteries as soon as possible.
EMPTY batt. LED: if this LED is blinking in red, the batteries are empty.

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
instructions of http://zennio.com/weee-regulation

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.
