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.

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.
