Issue:
How do I configure a 208v Smart-UPS RT or SRT for use with a 240v input?    

Product Line:
Smart-UPS Online (RT and SRT)

Environment:
All models, All Serial Numbers

Cause:
Smart-UPS RT and SRT units sold in North America are factory configured for 208v in/out.

Resolution:
The Smart UPS Online line has a very broad range of acceptable input voltages, and as such you do not need to do anything on the input side. By default the unit will accept the 240v input but continue to provide 208v output.

In order to avoid a sudden voltage shift in the event that the UPS goes to bypass it is recommended to configure the UPS output to match the UPS input.

For SURT Models:
This can be done via a Hyper terminal session, or more commonly using the Network Management Card interface. Before any changes can be made, you must first turn off the UPS. From within the Network Management Card web interface you would select the UPS tab. On the UPS tab we would select Configuration and then Power. Here we choose 240 VAC output and click Apply. The UPS will now output 240v. Note: Output voltage will not change if the UPS is left "on" while trying to make the change.  

For SRT Models:
This can be done using the LCD screen on the UPS or via the Network Management Card interface. Before any changes can be made, you must first turn off the output of the UPS. From the LCD screen go to the "Configuration" menu, then select "Output Setting" to adjust. Note: "Output Setting" will not appear in the menu if the UPS output is left on. From the Network Management Card interface, follow the same directions as the SURT that are listed above.

Please note that this is an unbalanced output with no neutral provided. If you need 120 v for your equipment you will still need to use a stepdown transformer.

The Stepdown Transformer must allow for 240v input, such as the SURT003 or APTF10KT01.

The AP9626, AP9627, and AP9628 would not be appropriate as they are designed for 208v input only.
