Figure 1 shows the connection outline of Z41 Lite:

Figure 1 Schematic diagram

Z41 Lite connects to the KNX bus through the built-in terminal (4). An external DC

power supply (12v / 24v / 29v) which delivers at least 150 mA of current is also

required. The KNX power and the external power must be electrically isolated and

provided by separate supplies, in order to avoid interference to the KNX bus. This

external power must be supplied to the device through the corresponding terminal (2)

provided within the original packaging, ensuring that each cable is properly connected

and respecting the electrical polarities –positive and negative– from the supply to the

device.

In addition to the external supply, Z41 Lite makes use of a button battery (LR44),

located at the corresponding slot (6), to help maintain the time and date updated in

case of a failure of the external power supply.
