These above-mentioned components are positioned according
to a typical standard layout. Using the layout in "Figure 5" as a
reference, define the approximate position in which each com-
ponent of the system will be installed.
Note 1 If the power supply cable is longer than 30 m, a cable

with larger cross-sectional area (3 x 2.5 mm
used and a safety earthing system must be installed
near the automation.
Note 2 If the BlueBus cable is longer then 20 m, up to maxi-
mum 40 m, it is necessary to use a cable with a greater
cross-sectional area (2 x 1 mm
Note 3 These two cables can be replaced by a single 4 x 0.5
mm cable.

Note 4 Before making the connection, verify that the output is
programmed on the basis of the device to be connected
(refer to the chapter "PROGRAMMING").

The cables used must be suited to the type of envi-
ronment of the installation site.

When laying the pipes for routing the electrical ca-
bles, take into account that any water deposits in
the junction boxes may cause the connection pipes
to form condensate inside the control unit, thus
damaging the electronic circuits.

Before proceeding with the installation, prepare the
required electrical cables by referring to "Figure 5"
and to that stated in the "TECHNICAL SPECIFICA-
TIONS" chapter.
