Powerware 9170 User Manual page 51

Confirm that the UPS is wired for the proper input voltage as shown in
Figure 28, and that the proper power modules (either split-phase or universal)
are installed to produce the desired output voltage. Do not mix the two types of
power modules in the same UPS cabinet.

Wiring Diagrams" on page 51 to complete the wiring for isolated
output.
See the wiring diagrams beginning on page 46 which show
output configurations. Make UPS output connections on the
backplane board terminating studs. Compression lugs (supplied
in the accessory kit) may be installed on the proper terminating
studs. Wires may also be terminated with ring terminals, which
are attached to the output terminating studs.
Figure 29 and Figure 30 describe output wiring configurations
for various output voltages. You must also set the operating
menu parameter 4-2-4 for the required output voltage as shown
in the wiring configuration drawings.
