4. The output voltage is the most important operating parameter
you must set as part of the initial configuration screens. Select
the desired UPS output voltage using the
Y
and
B
buttons.
Possible selections are 200, 208, 220, 230, and 240 Vac. (Low
voltages are derived from these voltages, as listed in Table 5 on
page 35 and Table 6 on page 43.) Press the button when the
desired output value is displayed.
5. If the system includes any external battery cabinets, record the
ampere-hour capacity of batteries installed in these cabinets.
Count the number of battery strings (two battery modules,
side-by-side equals one string). Each battery string contains
7.2 ampere-hours. Enter the total value in the next startup
screen.

6. The system signals an alarm when required output cannot be
maintained with the loss of redundant power modules. The
alarm is essentially disabled with a redundancy level set at 0.
If you want the system to notify you when the number of
redundant power modules is less than a specified level, enter a
redundancy level. Each increment above 0 indicates the
number of modules that can be removed from operation before
the alarm occurs. This setting only affects the alarm; the system
continues to operate as an N+X system even if this parameter is
left at the default value of 0.
