The above-mentioned components are positioned according to a
typical standard layout. Using the layout in "Figure 4" as a reference,
define 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
with larger cross-sectional area (3 x 2.5 mm
and a safety earthing system must be installed near the
automation.
Note 2 If the cable is longer then 30 m, up to maximum 40 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
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")..
m
The cables used must be suited to the type of
environment of the installation site.
m
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.
m
Before proceeding with the installation, prepare the
required electrical cables by referring to "Figure 4" and to that
stated in the "TECHNICAL SPECIFICATIONS" chapter.
