Installation

7.Plug the equipment to be protected into the UPS output 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 self￿test, 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.
