Webif TT, then you need the isolating transformer since the neutral is opened during a fault on the supply side. In such a case, since the UPS still has power, you need to give the load the neutral reference, thus the need for an isolating transformer. In a TN system, the neutral is not opened, thus you do not need the isolating transformer.
