Universal dimming actuator, 1-gang
Figure 4: Cable spacing
Minimum spacing between the mains voltage and bus/extension wires: 4 mm (Figure 4)
Figure 5: Connection of load
Observe ambient temperature. Ensure adequate cooling.
￭
Connect the device to KNX with the correct polarity.
￭
Connect load as shown in the connection example (Figure 5).
￭
If required, connect potential-free contacts or dew/leakage sensors to inputs 1...3, or NTC
temperature sensors to input 3 (Figure 2).
￭
Install the device in the appliance box.
￭
In secure operation: The device certificate must be removed from the device and stored
securely.
The COM reference potential must not be connected together with COM connections of
other devices!
4.2 Commissioning
Commissioning the device
In the as-delivered state, the actuator is passive, i.e. no telegrams are transmitted to the KNX.
The output is set to the universal dimming principle with automatic recognition of the load type.
Control of the output is possible via inputs 1 and 2, provided the bus voltage is switched on. In-
put 3 has no function.
