During operation as an output, the load (LED or electronic relay) is connected<br />
between the black and the coloured core. The coloured core represents<br />
the positive output voltage.<br />

Note:<br />
When connecting to an S0 impulse output (e.g. an energy<br />
consumption meter), it must be ensured that it is electrically<br />
isolated from the mains. The correct polarity should also be<br />
observed (“+” on the grey core).<br />
