:
The backfeed protection is compliant with standard IEC 62040-1.
p
urpose
:
The backfeed protection is for ensuring personnel safety against any risks of accidental energy return to the
input circuit. the backfeed protection imposes the automatic opening of an switching device in case of a mal-
functioning of the static switch.
Principle:
The backfeed protection consists of an electronic detection PCB internal to Green Power 2.0 and an external
electromechanical device for isolation from the power circuit. optionally, the backfeed protection device may be
built into the system. for further details about the size of the protective device, please see § 4. 7.
l
abel
:
A safety label bearing the following advice is available in the equipment:
the operator shall stick the label on the electromechanical device for isolation from the power circuit.
