Figure 30 and Figure 31 describe output wiring configurations for
various output voltages. You must also set the operating
menu424fortherequired output voltage as shown in the wiring
configuration drawings.
NOTE For Powerware 9170

UPS models with low-voltage hardwire output, it is
recommended to divide the total load as equally as possible between X1 and X2, as shown in
Figure 30.
NOTE Failure to balance the loads may cause an overload alarm even if the full capacity of
the UPS has not been reached.

NOTE The factory-default wiring for all high-voltage receptacles in a chassis without a
power cord is 3-wire plus ground input. If you have a universal power module (ASY-0674), all
receptacles MUST be re-wired for a 2-wire plus ground input configuration as shown in
Figure 31.
