General information regarding the electrical connections
For further information see chapter
"Electrical connection", page 26.
■ The total output of all components con-
nected directly to the control unit (e.g.
pumps, valves, message facilities,
contactors) must not exceed 1000 W.
If the total output
≤
1000 W, the indi-
vidual rating of a component (e.g.
pump, valve, message facility, contac-
tor) can be greater than specified.
However, never exceed the breaking
capacity of the corresponding relay
(see page 141).
■ In the delivered condition, terminals
may have been pre-allocated (subject
to appliance version).
If two components are connected to
the same terminal, press both cores
together into a single wire ferrule.
■ The KM BUS wires are interchangea-
ble.
■ The neutral and earth conductors of all
components are connected to the lus-
ter terminals X2.N and X1.
