UPS ELECTRICAL INSTALLATION

Figure 29 and Figure 30 describe output wiring configurations for various output voltages. You must also set the operating

menu 4 2 4 for the required output voltage as shown in the wiring configuration drawings.

NOTE For Eaton 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 29.

NOTE Failure to balance the loads may cause an overload alarm even if the full capacity of the UPS has not been reached.

Figure 29. Split-Phase Power Modules

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 30.
