3. OUTPUT terminals and the Earth Ground a significant voltage reading will be obtained This voltage is due to a small leakage current and is not considered a problem since only 1 or 2 mais involved Output Isolation Many applications require an isolated output primarily for safety reasons when supplying power to a device under test especially if there will be other monitoring eguipment connected to the device Other applications can take advantage of the low leakage current of the Converter about 1 or 2 ma This can be useful in systems where the individual leakage currents of the components might exceed the allowed leakage current of a ground fault interrupter Other applications require that the output have a connection to the utility NEUTRAL Normally this would be OUTPUT terminal N The exception would be a two phase output where L1 would be the connection to the system NEUTRAL The Converter is supplied with a short jumper wire If the system NEUTRAL is used to power the INPUT terminals and it is required that the OUTPUT be connected to NEUTRAL this jumper can be employed to make this connection If the INPUT is supplied by two phase AC or by two phases of a three phase system in other words if you have only two incoming power wires this NEUTRAL would not be present and an external wire from the desired OUTPUT terminal to the system NEUTRAL would be reguired See INPUT CONNECTION DIAGRAM on next page Basic diagram of output
