2.11 Wiring
•
Access the electrical parts as described in paragraph
2.4.
•
An on/off switch with delayed fuse or an automatic
circuit breaker (2A) must be installed to supply power
to the system.
•
Because the wiring features a suppression filter, as
required by the applicable laws and standards, which
naturally induces leakage current to the ground, it
is best to install selective differential circuit breakers
upstream of the system.
•
For safety reasons, the on/off switch referred to
above should be installed near the device or at any
rate in open view.
•
The power cables must be equipped with copper
conductors having the following unitary sections (the
values indicated refer to a maximum line length of
15m). The cables must be appropriate for the type
of installation, in accordance with the applicable CEI
standards.
