5.1 Installation notes
The VAV terminal unit was manufactured and configured
for each project. The control components are prewired
at the factory. For installation of electrical control com-
ponents, the supply voltage must be connected, and, if
necessary, also signal or bus lines must be connected.
The connection is made according to the information on
the control components or connection diagrams and the
commissioning instructions for the respective control
component,

. These must be observed for
project-specific wiring diagrams. The voltage ranges
and terminal connections indicated on the control com-
ponents must be observed!
Personnel:
Skilled qualified electrician
Observe during installation:
Legal and official regulations, in particular VDE
guidelines
Consideration of the technical connection conditions
(TAB) of the local grid operators
Wiring work for supply voltage and signal lines, to
be provided by others
The sizing and manufacture of connections and
wiring provided by others must be carried out in
accordance with the recognised regulations of elec-
trical engineering.
Comply with wiring guidelines and project-specific
circuit diagrams of the control components.
The electrical connection may only be made after
complete installation of the control unit.
For control components with 24 V supply only
supply via safety transformer
If several volume flow rate controllers are connected
to one 24 V network, it is important to ensure that a
common neutral or ground wire is used and that this
is not connected to any other wiring.
Suitable wire clamping brackets must be provided
for all connecting cables.
The control component does not contain any parts
that can be replaced or repaired by the user and is
only allowed to be opened by the manufacturer.
