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

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 maximum
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.

When laying the pipes for routing the electrical
cables, 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.
