LABELS AND WARNINGS
The GFDI comes with a number of warning and identification labels pre-
installed by OutBack. The following two labels are installed by the end
user or the installer.
Install this label to the battery enclosure/cabinet.
Install this label on the outside of the panel box location of the GFDI.
PV ARRAY GROUND FAULT
DETECTOR INTERRUPTER
CAUTION: RISK OF ELECTRIC SHOCK
NORMALLY GROUNDED CONDUCTORS MAY BE
UNGROUNDED AND ENERGIZED WHEN A GROUND-FAULT
IS INDICATED.
Many types of ground-fault detection and interruption equipment
break the negative-to-ground bond to interrupt the fault currents,
and the now ungrounded PV negative conductor generally is
open-circuit voltage below the ground reference 150 volts.
