6.1.1 Setup > SYSTEM
The "Setup > System" submenu is used to inform the UPS of its operating environment in regards
to the following parameters:
•
Nominal input and output values of the UPS.
•
Number of battery strings.
•
Output power capacity.
•
If the UPS is being operated in parallel with one or more additional UPSs.
•
On what conditions should the UPS be shutdown when in battery mode, and should the UPS
be automatically restarted when the ac mains power returns.
•
Interval between automatic tests of the controller battery.
•
Testing the remote control panel.
•
List any maintenance alarms.

•
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 main 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 main 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
