Emerson 610 Manuel D’Utilisation

As previously mentioned, Series 610 SCC requires a bypass input neutral for sensing and monitoring. 

With a wye-connected input source, the installer should always connect the building service neutral to 

the System Control Cabinet (SCC) output neutral to achieve this. When the building service is delta-

connected, however, the installer must take special steps to ensure reliable UPS functioning.
If the building service is corner-grounded delta or impedance-grounded wye, the UPS requires the 

Series 610 Isolated Neutral Kit, as do each of the UPS modules. This kit uses control isolation trans-

formers to create a reference point. For this application, the SCC output neutral must not be bonded 

to the SCC ground.
