APPLICATIONS DALI MCU 

 

 

 

Figure 4: Wiring scheme with 4 control points for addressing up to 50 ECG 

 

Laying the control line in indoor installations is generally not 

difficult. For the two control wires (DALI signal), you can use 

two wires in the same 5-pole NYM cable that provides the 

mains supply. You may chose any arrangement for the 

parallel wiring, but a closed circuit of the control line is not 

permissible. Moreover, the total running length of the control 

line must not exceed 300m. 

 

It is important to observe correct polarity of the feed cables 

when connecting the control line with two or more DALI MCU 

control devices. 

 

 

Because each of the devices has its own power supply, the 

connections must not be mixed up – i.e. the positive wire 

must be connected to Da+ and the negative wire must be 

connected to the Da- connector of the control device. 

Erroneous wiring, however, will not destroy the device, 

because the DALI MCU comes with an inverse-polarity 

protection feature – however, correct operation will only 

resume when the wiring has been corrected to match device 

polarity. It is not necessary to observe control line polarity on 

the ECG side.
