CHAPTER 3: INSTALLATION
Using the Step-Down Transformer
•Connect the Step-Down Transformer to a UPS for continuous power during a utility power failure.
•The transformer has an efficiency of 90%. This requires 5500 VA for a 5000 VA load, 5000 VA for a 4500 VA load, and 3900 VA for a 3500 VA load. Be careful not to overload your branch circuit or UPS.
•For the AP9621, SYTF2, and SURT005 models to output the full 5000 VA, the input must be hardwired to a 5500 VA source.
•Operating the Step-Down Transformer below its specified input voltage range may cause it to overload and shut down to prevent it from over-heating. When connecting directly to a branch circuit, ensure that the line voltage is within specification. When connecting to a UPS, ensure that the line voltage into the UPS is within specification before transferring to bypass.
•Operating the Step-Down Transformer above its input voltage range may cause equipment damage.
