4.1.15 Connection of the I²NET network panel to earth and SCP674V122T panel
In g. 4.18 shows an example of an I²NET network, generator n.1 is also equipped with a SCP674122T panel
for local control of the appliance.
The ambient temperature and the external temperature for generators n.1 and n.2 are measured with the
probes connected to the relative appliances; generator 3 is managed with the temperatures detected by the
probes (PE; PA1) connected to the network controller panel
SUPPLY 1N ~ 50 Hz 230 V
