Isolated Output Wiring Diagrams

The wiring diagrams in this section are unique and specific to
installations in which the output of the Powerware 9170
galvanically isolated from the input.
Figure 35 and Figure 36 describe output wiring configurations for various
output voltages. Use Table 9 to identify the wiring diagrams and connect
the output AC wiring to the proper Powerware 9170
terminals. You must also set the operating menu parameter 4-2-4 for the
required output voltage as shown in the wiring configuration drawings.
NOTE
charger modules in the system.
NOTE
neutral-to-ground wire (N-G bond) to UPS output terminal as illustrated
in Figure 37 on page 53.
