2 INSTALLATION
2.1 Preliminary Information
Due to the various types of ERMO 482X3
PRO
barrier, there are some different kinds of
installation and fixing unit types related to user requirements.
2.2 Number of Sections
Having to design protection with volumetric barriers of a closed perimeter
,
besides having to split
the perimeter within a certain number of sections that take into account the management need of
the entire plant, it must be remembered that it is always preferable to install an
even number of
sections
. This consideration is bound to the fact that the likely reciprocal interferences between
adjacent sections are annulled should at the vertices
( cross )
of the polygon, resulting from the
installation of the various sections, be installed
two equipment with the same name, two
transmitters or two receivers
. It is evident that this might occur only if the number of sections is
even. Should it not be possible to have an even number of sections then some careful
considerations must be made on interferences that might likely occur in order to find the vertex
point where retained best to place the transmitter near the receiver. The following pictures show
some typical cases for which the most correct solution is given (see figure 1).
