Separate bypass:
if the separate bypass option is present, protective devices must be present on both the main power supply line and the
bypass line.
Note: the neutral of the input line and that of the bypass are commoned inside the equipment, so they must refer to the
same potential. If the two power supplies were different, an isolation transformer would have to be used on one of the
inputs.
