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
switched mains voltage (l) to the common contact  of the
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.
