2.4.3 Radio interference suppression of dimmable luminaires The use of dimmable ECG is only approved in luminaires of protection class I (PC I) as only here is adequate grounding assured. Note: When dimming, the operating frequency of the lamp and the lamp burning voltage increases at the same time which can lead to elevated leakage currents. Leakage currents emerging from the lamp always flow back into the ECG because the current circuit must be closed. To keep cable-related interference as low as possible, the leakage current is offered a different return path, the ground conductor (=casing) and the PE connection of the ECG. In brief: Dimming is not possible without grounding. Dimmable ECGs only function in PC I luminaires and not in PC II luminaires as these have no protection contact. Connecting the dimmable ECG to the functional ground is not permissible. Radio interference suppression with PC I L N R Lamp ECG Grounded metal plate or reflector PE Figure 5: Protection class I luminaires The maximum 50 Hz leakage current of the ECG via the ground fault circuit interrupter (FI switch) is 0.5 mA. • Mains cables and control lines may be routed together and should be laid close to the luminaire wall • Mains and control cables must not be laid close to the lamp cables • If crossovers of mains and lamp cables are unavoidable, they should cross perpendicularly • Do not lay the PE conductor together with the lamp cables • Do not use shielded lamp cables (reduction of capacity leakage currents) • The OSRAM <strong>DALI</strong>/DIM ECG must always be installed near the lamp(s) so that the lamp cables can be kept short in the interests of good radio interference protection 14
