pecifications on operation of the LEDs
In correspondence to each status of the inverter indicated by the constant
or intermittent lighting of the specific LED, the display
07
also shows
a message identifying the operation which is being carried out or the
defect/anomaly recorded (see specific chapter).
In the case of malfunction it is extremely dangerous to intervene personally to try and eliminate
the defect. The instructions below must be followed scrupulously; if you do not have the
necessary experience and training to intervene safely, please contact a specialist.

ED insulation fault
Interventions after warning of insulation fault
When the GFI LED comes on, first try to reset the warning by pressing
the multi-function ESC button on the keyboard
08
.
Should the inverter reconnect normally to the grid, the fault was due to
temporary phenomena.
You are advised to have the plant inspected by the installer or a specialist should this
malfunction occur repeatedly.
Should the inverter not reconnect to the grid, isolate it on both the AC and
DC sides (by using the disconnect switches), then contact the installer or
authorised centre to repair the fault in the photovoltaic generator.
