[note 3]
Maximum length 50 m
Note 1 If the power supply cable is longer than 30 m, a cable
with larger cross-sectional area (3 x 2.5 mm
2
) must be
used and a safety earthing system must be installed
near the automation.
Note 2 If the BlueBus cable is longer then 30 m, up to maxi-
mum 50 m, it is necessary to use a cable with a greater
cross-sectional area (2 x 1 mm
2
).
Note 3 These two cables can be replaced by a single 4 x 0.5
mm
2
cable.
Note 4 If more than one edge is present, refer to the “STOP in-
put” paragraph for the type of connection recommend-
ed.
Note 5 Movable edges must be connected to sliding leaves us-
ing special devices, which enable the connection even
when the leaf is moving.
a
Before proceeding with the installation, prepare the
required electrical cables by referring to “Figure 4”
and to that stated in the “TECHNICAL SPECIFICA-
TIONS“ chapter.
a
The cables used must be suited to the type of envi-
ronment of the installation site.
a
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.
