CHAPTER 3: INSTALLATION About Your Step-Down Transformer This Step-Down Transformer is designed for use with a UPS that provides a higher output voltage (200 or 208 VAC). It converts the output to a lower voltage (100 or 120 VAC); a common voltage level used by many computers and accessories. The Step-Down Transformer may also be used as a Figure 1: Step-Down Transformer stand-alone device. Table 1: System Configurations and Model Numbers Complete Available Nominal Nominal Fr

CHAPTER 3: INSTALLATION Connecting Load Equipment Plug all load equipment into PDU receptacles. • For AP9621, SYTF2, SYTF2J, SURT005, and SURT006 models, the receptacles are divided into 4 groups; each group is protected by a 15-amp circuit breaker. A colored label identifies each circuit and its circuit breaker. • For SUTF3, SYTF3 and SYTF3J models, the output is divided into 4 groups. Each group is protected by a 20-amp circuit breaker that contains one (1) receptacle. • W

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. •
