UPS Installation Configurations - Three Phase
The table below is a UPS design assist chart for various configurations that UPS may be installed in.
There are many configurations of UPS by which a single UPS Module may be installed. The table below may help selecting the one best for you. Please note if different input and output voltages are selected you may not utilize any configuration with an external maintenance bypass unless you also install a transformer in the external bypass circuit also. In general designing UPS with different input and output voltages is an engineering error as it precludes the basic external maintanance bypass that all IT users of UPS want once the understand it. If you are headed this route, stop, it is in your best interest to learn more.
In the section for Configuration #11 we have linked varioius alternatives that provide additional breakers for either two inputs to the UPS or for directly serving multiple loads. These configuration options may be provided on other Configuration #s but are shown only within Configuration #11 to simplify the chart.
