pecifications on the operation of the LEDs
In correspondence to each status of the inverter indicated by the con-
stant or intermittent lighting of the specific LED, the display
b10, also shows a message identifying the operation which is being car-
ried out or the defect/anomaly recorded (see specific chapter).

nate the defect. The instructions below must be followed scrupulously; if you do not have the

Interventions after warning of insulation fault
When the red LED comes on, first try to reset the warning by pressing the
multi-function ESC button on the LED panel
Should the inverter reconnect normally to the network the fault was due
to temporary phenomena.
You are advised to have the plant inspected by the installer or a specialist should this malfun-
ction 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.
