Separate bypass on separate lines:
if the separate bypass option is present, all protective devices will have to be placed both on the main supply line and on the line
dedicated to the bypass.
Note: the input line and bypass line neutral are shared inside the device; therefore, they will have to be connected to the same
potential. If the two power supplies are different, you must use an isolation transformer on one of the inputs.
