3.2.2 Connecting the power supply, pump and mixer

(mains voltage side)

The allocation of the electrical connections
depends on the system installed. The
description shown in Fig. 8 to Fig. 11, starting
on page 53 onwards, is a possible suggestion
for making the electrical connections. Some of
the steps are not shown in black. 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.
▶ Route cables through the grommets, connect them as
shown in the connection diagrams and secure them with
the strain relief pieces, which are supplied as part of the
scope of delivery ( Fig. 8 to 11, starting on page 53
onwards).
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.
3.2.3 Connection diagrams with system schematics
The hydraulic diagrams are only schematic illustrations and
provide a non-binding indication of a possible hydraulic circuit.
▶ Install safety equipment in accordance with applicable
standards and local regulations.
▶ For further information and options, refer to the technical
guides or tender specification.

4 Commissioning
First make all electrical connections correctly
and only then carry out the commissioning!
▶ Follow all installation instructions for all
components and assemblies in the
system.
▶ Only switch on the power supply when all
modules are set up.
1. Set the code switch on other modules as applicable. The
code switch on the module MP 100 has no function.
2. Connect the entire system to the mains voltage.
When the module indicator lights up green continuously:
3. Commission and set up the user interface as described in
the accompanying installation instructions.
