This LED indicates that one of the protective devices fitted on the power source
has tripped. The protective devices fitted on the power source comprise: thermal
protection; infeed overvoltage or undervoltage; overcurrent protection.
When one of these protective devices is activated the LED illuminates and one of
the following messages is displayed on the digital instrument, depending on the
device that has tripped:
F07 undervoltage/overvoltage.
F06 overcurrent.
F02 thermal protection.
