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.

(a) Split-Phase Power Modules

(b) Universal Power Modules

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.
