Connecting the plant components


Connect the plant components to the output terminals of relays 1
to 19 (e.g. valves).

If the plant components require mains voltage, connect the
l PE switched mains voltage (l) to the common contact
respective relay (see the connection example for 230 VAC on the
left).

Connect the neutral conductor of the plant component to one of the
terminals (n).

For components with a protective earth conductor connection,
connect it to the PE connection.

Ensure that the leads are held securely in the terminals.
