5. Wire the UPS for the proper input voltage as shown in Figure 28.

Split-phase power modules (model ASY-0673, with brown labels on

the front) are capable of supplying two output voltages: 100/100

for 200, 110/110 for 220, 120/120 for 240, 120/120 for 208, or

127/127 for 220 Vac, as selected through the front panel display.

These modules produce two output voltages, typically required in

North America, South America, and Japan.

Universal power modules (model ASY-0674, with black labels on

the front) are capable of supplying a single-phase output voltage:

200, 208, 220, 230, or 240 Vac, as selected through the front panel

display. These modules produce a single output voltage, typically

required in Europe, the Middle East, Asia, and Africa.

C A U T I O N

Confirm that the UPS is wired for the proper input voltage as shown in Figure 28, and that

the proper power modules (either split-phase or universal) are installed to produce the

desired output voltage. Do not mix the two types of power modules in the same UPS

cabinet.

6. For units manufactured before 2009 that have an isolated transformer

option. See Chapter 5, “Isolated Output Wiring Diagrams” on

page 53 to complete the wiring for isolated output.

7. See the wiring diagrams beginning on page 48 for output

configurations. Make UPS output connections on the backplane

board terminating studs. Compression lugs (supplied in the

accessory kit) may be installed on the proper terminating studs.

Wires may also be terminated with ring terminals, which are

attached to the output terminating studs.
