The wiring diagrams in this section are unique and specific to
installations in which the output of the Powerware 9170 UPS is
galvanically isolated from the input.
Figure 37 through Figure 40 describe output wiring configurations for
various output voltages. Use Table 6 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.
