Wire the UPS for the proper input voltage as shown in Figure 9.

The Avaya RS9 UPS uses split-phase power modules that
supply 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.

(3-Wire Plus Ground Input) (2 PEN)

100/200, 110/220, 120/208, 120/240, 127/220 Vac
