Installation
14
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 re-
spective 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
No.
