The allocation of the electrical connections depends on
the system installed. The description shown in Fig. 12 to
Fig. 19, starting on page 83 onwards, is a possible
suggestion for making the electrical connections. Some
of the steps are in different colors. This makes it easier to
see which steps belong together.
▶ Only use electrical cable of comparable quality.
▶ Ensure that the power supply is connected to the correct phases.
A power supply via an earthed safety plug is not permissible.
▶ Only connect components and assemblies to the outputs in
accordance with these instructions. Do not connect any additional
control units, which control other system components.
The maximum power consumption of the connected
components and assemblies must not exceed the output
stated in the module specifications.
▶ If the mains voltage is not supplied via the electronic
system of the heat source, install a standard all-pole
isolator (in accordance with EN 60335-1) on site to
disconnect the mains voltage.
▶ Route cables through the grommets, connect them as shown in the
wiring diagrams and secure them with the strain reliefs, which are
supplied as part of the scope of delivery ( Fig. 11 to 18, starting at
page 83).
