Ground fault indication

General

The FRONIUS IG is equipped with a ground-fault detection and interrupti-
on (GFDI) circuit as required by UL 1741 and the National Electrical code.
The array's negative conductor is connected to the grounding system in
the inverter. If a ground fault occurs in the DC cabling, the inverter discon-
nects 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 FRO-
NIUS IG is blocked from reconnection to the grid until the following ac-
tions are taken:
- Turn 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
WARNING! An electric shock can be fatal. Normally grounded con-
ductors may be ungrounded and energized when a ground fault is
indicated. The ground fault has to be repaired before operation is
resumed.
NOTE! When a defective fuse is changed, only replace it with a
"Littlefuse KLKD 1 AMP 600V" fuse.
- Turn the AC and DC disconnect to position ON (closed circuit)
