10.5Notes on the wiring
Warning: Before starting to wire up the system, ensure that all the con-
ductors are disconnected from electrical supply. Electricity must also
be disconnected before plugging or unplugging the connectors. Never
touch the controller wires or connections.
Due to the limited space you have to lead the wires inside the desired cable
harness and not on the other side of the clamping block. The clamping block
can be set in therefore through light side pressure from the catch and set in
the other way.
For the wiring always note the numbering on the base plate.
Warning: The connection cables from the operation to the heating
circuit module (databus)
have to be installed separate from the low
voltage cables (230 V).
Note if you do not consider this it can cause malfunction of the
heating control!
Please note the appropriate operation instruction and the connection scheme
when connecting the connection cables of the operation module to the heating
circuit module of the boiler.
Before putting on the operation module on the base plate take care that the
programming switches (DIP-switch) of the plant are set (see the following
chapter).
