Connect system components


Loosen the strain relief of the cable ducting (union nut).

Take out the blanking plugs of the corresponding cable ductings.

Push through the cable of the component.

Tighten the union nut of the cable ducting and so establish the
strain relief.

Connect the system components to the output terminals of relays 1
to 4 (e.g. valves)

If the system components require mains power, connect the
switched mains voltage (l) to the root contact
relay (see accompanying connection example for 230 VAC)

Connect the neutral conductor of the system component with one
of the terminals (n)

For components with a protective conductor connection, connect
them to the PE connection.

Ensure that the cores in the terminals are securely in place
(Illustrated position of relays: Device without current, mains: 230 V)
Indicate external voltage on the relay contacts!
If you connect system components that do not operate using the de-
vice voltage, you can apply external voltages to the relay contacts.
This external voltage cannot be switched off via the device mains
switch
There is a danger of electric shock!
Affix a warning to the device in this case (e.g. a sticker as shown left).
