This screen shows that there is no input or output taking place yet, because the UPS logic
has not allowed any connections to occur. The AC line voltages are being read, because
they are available, but there is no current flowing.
4. Rotate the Transfer Switch clockwise 1/4 of a turn to the "ON UPS" position. The AC line
green light should come on steady, indicating that the UPS is able to derive power from the
AC utility. The Battery discharging and Attention lights should go off. The main screen
should show normal operation, although no load may be indicated, provided the external
loads are not yet turned on. Normal operation is best indicated by the fact that no flashing
messages are present on the display.
5. Before the load is turned "ON," consult the LCD screen to confirm that the proper voltages
are present.
6. Assuming that normal operation was observed, you can now turn ON your load. If during
this procedure the LCD screen displays an overload warning, your load is too large for the
UPS, and some must be removed or the UPS will shut down. Short duration overloads that
are a result of inrush currents in your load equipment being turned on could cause
momentary overload conditions. Such a condition may not be a cause for alarm. The LCD
screen will indicate any problems detected.
