Electrical connection

WARNING:
Risk to life from electric shock!
Touching live electrical parts can cause an electric shock.
▶ Before working on electrical parts, disconnect all phases of the
power supply (fuse/circuit breaker) and lock the isolator switch to
prevent unintentional reconnection.
WARNING:
Danger to life from electric current!
Incorrectly connected electrical cables can result in faulty operation with
potentially dangerous consequences.
▶ When making the electrical connections, refer to the connection
diagrams for the individual devices and components.
▶ When performing maintenance, label all power cables before
disconnecting them.
NOTICE:
Material damage if the maximum current consumption is exceeded!
Short-term high (start-up) currents can can damage electrical
components.
▶ When connecting external components to the control unit, make sure
that the sum of the individual currents consumed by these
components does not exceed the maximum current consumption
( data plate).
Note the following when making electrical connections:
▶ Electrical work on heating systems must only be carried out by
qualified electricians. If you are not suitably qualified, ask a licensed
heating contractor/electrician to establish the electrical connection.
▶ Make sure that all boiler components are earthed via the control unit
and burner control unit (earthing is a constituent part of the control
unit used).
▶ Observe all local regulations!
6.1

Installing the control unit

The boiler is supplied with the control unit that was assigned when
placing the order. The boiler can only function fully with an installed
control unit.
The control unit must be mounted at the designated position on
the boiler.
▶ To install the control unit, observe the corresponding technical
documentation.
▶ When making the electrical connections, refer to the connection
diagrams for the individual devices and components
(Chapter 17.4, page 59).

6.2 Establishing the power supply connection and
installing the cables
Establish a permanent connection to the power supply in accordance
with the locally applicable regulations.
▶ To connect the cables, observe the relevant technical documentation
of the installed control unit.
WARNING:
Danger to life from electric current!
Incorrectly connected electrical cables can result in faulty operation with
potentially dangerous consequences.
▶ When making the electrical connections, refer to the connection
diagrams for the individual devices and components.
▶ When performing maintenance, label all power cables before
disconnecting them.
DANGER:
Risk of material damage due to hot boiler components!
Hot boiler components can damage electrical cables in close proximity.
▶ Make sure that all cables are routed through the conduits provided.
NOTICE:
Material damage due to induced overvoltage!
Incorrectly installed cables can lead to induced overvoltages which can
cause the control unit to malfunction or be damaged.
▶ Route 230 V cables and extra-low voltage cables separately.
▶ Route all cables that run towards the back through the cable conduit.
▶ Route all cables through the cable conduits to the control unit and
connect them as shown in the connection diagram.
NOTICE:
Fault due to power failure!
▶ When connecting external components to the control unit, ensure
that sum of currents consumed by these components does not
exceed the maximum current consumption of the installed control
unit.
▶ Secure all cables with cable clips (control unit scope of delivery).
Inserting function modules
For information on the function modules, refer to the relevant technical
documentation.
▶ Observe technical documentation of the control unit and the function
modules.
