If the system is exposed to a lot of electrical interference, the use of ferrite as close as
possible to the connection is recommended (see Figure 6 Example of a connection with
cable seal and ferrite).
Once the fire panel is mounted on the wall, the connecting of equipment may start. The
loops, the mains and the additional elements are connected to the base plate through the
holes on the top. The hole located away from the rest is for the mains.

WARNING!
The 110 VAC or 230 VAC power must be connected to the power supply through an
external magneto-thermal switch.
The mains cable should have a minimum section of 1.5 mm².
To avoid possible short circuits and interference, the mains cable must be kept away
from the zone connection cables and from the communication ports.
To ensure 'clean' connections, the use of PG11-type cable adapters or seals
is recommended. In this way the cable is firmly fixed to the panel. The use of
pressure-sensitive flanges to fix the cables to the housing of the exchange is
also recommended.
