NOTE:
To prevent electromagnetic disturbances generated by power cables from generating
"bounced" voltage, current and frequency readings of the Power Meter, always wrap the
signal cables on dedicated cavities and appropriately separate, trying to avoid wiring lengths
greater than 100 meters.
NOTE:
In the presence of electromagnetic disturbance, the voltage and frequency values
detected by the Power Meter could be "bumped" and this could cause the Solar Eclipse
"block" status, which detects network parameters outside the admitted range.
•
Prepare the grid sensor wire with a three-pole
terminal using an UTP twisted pair cable or a
shielded STP twisted-pair cable with a minimum
0.25 mm square section (see image below).
WARNING
: If the inverter has no isolating
transformer, double insulated signal cables
(double sheath in polyethylene) should be used
and do not ground any screen stocking.
•
Use two pairs of twisted wires, making sure to connect the central PIN (O) to both pairs as shown
in figure 4. In the case of STP shielded cable, connect the braid to the central PIN (O),
remembering to insert the PG9 and note the color of the wires.
