Powerware 9170 ISOLATED OUTPUT WIRING DIAGRAMS

ISOLATED OUTPUT WIRING DIAGRAMS

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.

NOTE For isolated outputs, all power modules in the Powerware 9170 UPS cabinet must be split-phase modules, which have blue labels.

NOTE In isolated-output installations, connect the UPS green and yellow neutral-to-ground wire (N-G bond) to UPS output terminal as illustrated in Figure 36 on page 45.
