Ground fault indi-
cation If a ground fault occurs in the DC cabling, the inverter disconnects from the grid.
The fault is indicated by the red ground-fault LED and the service code "434" is shown on
the display.
In this situation, the inverter is blocked from reconnection to the grid until the following ac-
tions are taken:
- Switch the AC and DC disconnect to position “OFF“ (open-circuit)
- Remove the ground fault in your photovoltaic system
- Test the GFDI fuse and replace if necessary
- Switch the AC and DC disconnect to position “ON“ (closed circuit)
Status Codes on
Fronius IG with
Several Power
Stage Sets A special status diagnostic is run if an error occurs in an inverter with several power stage
sets.
It is also possible to call up status codes even if there is no actual error in existence. This
form of status polling may be found in the section "The Setup Menu."
Display during normal operation
When there is an error in one of the power
stage sets, the display flashes between
"STATE" and the corresponding status
code
(e.g., "STATE 515")
and
"ENTER"
- Press the "Enter" key twice
NOTE! When a defective fuse is changed, only replace it with a "Littlefuse KLKD
1 AMP 600V" fuse.
