 Nominal system output voltage. You can modify the nominal output voltage to any of the
values listed on the screen, but first you must turn off the UPS by means of the ON/OFF
button on the System menu screen. Obviously, you should not change the output voltage
unless you are sure that the new value is appropriate for the load devices. An inappropriate
output voltage can cause permanent damage to the load devices.
 Nominal system frequency. The output frequency of the UPS can be set to either 50 Hz or
60 Hz. Before modifying the UPS nominal frequency, the UPS must be turned off by means of
the ON/OFF button on the System menu screen. Obviously, the nominal system frequency
chosen should be the same as the nominal frequency of the rectifier input and bypass voltage.
 Frequency tracking range. The inverter frequency is normally governed by the frequency of
the bypass voltage, which will be a nominal 50 or 60 Hz. There may be natural fluctuations in
the bypass frequency. The frequency tracking range lets you determine how far away from the
nominal frequency the inverter will follow the bypass frequency. When the bypass frequency
fluctuation exceeds the frequency tracking range, the inverter stops following the bypass
frequency and begins instead to determine its frequency by means of the UPS's internal clock.
