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.
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 power consumption (consider the
power consumption of the boiler) does not exceed the maximum
0010039342-001
current consumption (control unit 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 system components are earthed or connected to
the equipotential bonding (protective earth is a constituent part of
the control unit used).
▶ Observe all local regulations!
Connect cables as shown in the connection diagrams (Chapter 12.4,
page 40).
