receptacles.
DO NOT protect laser printers with the UPS because of the
exceptionally high power requirements of the heating elements.
NOTE If you are using the Load Segment feature, see page 24 for more information
on controlling and assigning the load segments.
8. To start the UPS, press and hold the button until you hear
the UPS beep (approximately one second). The LCD briefly
displays
On Delay and the
indicator illuminates. Then the
UPS conducts a selfĆtest, briefly displaying
On BATTERY. If an
alarm condition occurs, see Table 10 on page 37.
When the self-test is complete, the LCD displays On Line
indicating that power is available from the UPS output
receptacles.
9. If you installed optional EBMs, configure the number of EBMs
through the front panel so that the UPS can estimate the
available battery run time (see Configuration Mode" on
page 17).
NOTE The batteries charge to 90% capacity in approximately 4 hours. However, it is
recommended that the batteries charge for 6 to 24 hours after installation or long-term
storage.
