Chapter 5 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 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
+
system power
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 Do NOT install more than seven power and/or optional battery
charger modules in the system.
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 37 on page 53.
