WIRING AND CONFIGURATION OF THE ECG

Figure 18a shows the setup if only 3DIM ECGs are con-
nected to the SD control switch. In case other ballasts
or loads are supplied via the SD line (e.g. L2) or an exter-
nal surge protection device is connected to this port, an
additional relay needs to be used within each luminaire
(see ﬁ gure 18b), unless something different is mentioned
in the product- related documents (data sheet or instruc-
tion sheet). The used relay should be suitable for low
switching currents < 1 mA (mostly gold plated contacts).

The SD control switch shown in ﬁ gures 18a/b can be a re-
lay connected to a timer with a remote HIGH/LOW voltage
signal.

For details, please refer to the 3DIM Tool manual.
