UPS Tab

When the program starts, the following window will open displaying the UPS model along with the
current UPS settings. This information can be updated at any time using the REFRESH button.

Output Voltage

The Output Voltage displayed is the nominal input/output voltage. This is not a voltmeter and will
display the nominal voltage whether the UPS is on or off. The drop down box will show the alternate
voltages available. Select the voltage that matches the nominal utility in your location.
8.5.2

Auto Restart

The UPS will provide computer grade power during power outages. If input power is unavailable for
an extended time, the UPS will shut down when batteries are depleted or a shutdown signal is sent by
the computer operating system to limit battery depletion (serial data or contact closure). If Auto
Restart is enabled (check mark in box), the UPS will restart when input power is restored. If the UPS
turns off power to the load for any other reason, manual restart is required (See 8.6 - Options Tab
for exceptions). Click on the box to remove the check mark and disable Auto Restart.
8.5.3

Frequency Selection

The UPS is normally designed for 50Hz or 60Hz operation. The factory default corresponds to the
model. All models are capable of being used as 50Hz or 60Hz systems. The UPS will automatically
sense the utility frequency when first plugged in and set the nominal frequency to match. Therefore,
for all normal use the Auto Sense button should be selected.
Some special applications require that the UPS be used as a frequency converter. Frequency con-
verter 50Hz or frequency converter 60Hz may be selected.
Note that frequency converter operation disables the Bypass. If, for any reason, the UPS inverter is
unable to power the load, the alternate bypass to utility power will not be available and power will be
removed from any load.
