Ground Fault,
Excessive Leakage
Current
A ground fault condition has been
detected. Leakage current is
greater than the allowable limit.
Check the array for an
unintentional reference to ground.
DO NOT TOUCH
any equipment
(including, but not limited to: the
inverter, the PV array disconnect
switch, the PV array combiners, the
PV panels, or the PV racking
system). Immediately contact the
installer or another qualified person
to locate and repair the source of
the ground fault.
8
Ground Fault,
Isolation Resistance
Low
A ground fault condition has been
detected. Insolation resistance
between the DC conductors and
ground is below the allowable
limit. Check the array for an
unintentional reference to ground.
DO NOT TOUCH
any equipment
(including, but not limited to: the
inverter, the PV array disconnect
switch, the PV array combiners, the
