Confirm that the UPS is wired for the proper input voltage as shown in Figure 25, and

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

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

UPS cabinet.

Figure 25. UPS Input Wiring

UPS Output Wiring Connections (Non-Isolated Installations)

Figure 26 and Figure 27 describe output wiring configurations for

various output voltages. Use Table 5 to find the desired wiring diagrams

and connect the output AC wiring to the proper Powerware 9170 system

power terminals. You must also set the operating menu parameter 7-3-4

for the required output voltage as shown in the wiring configuration

drawings.

NOTE All power modules in the Powerware 9170 UPS cabinet must be of the same

type: Universal (single-phase) modules have white labels; split-phase modules have

blue labels. Output for each type of module must be wired differently.
