7On the UPS status summary screen, press the button to check for active alarms or notices. Resolve any active alarms before continuing. See “Troubleshooting” on page 59.

If there are no active alarms, a “No Active Alarms” message appears.

8Verify that the Normal icon appears on the UPS status summary screen, indicating that the UPS is operating normally and any loads are powered (see Table 4 on page 32).

9If an optional EBM is installed, see “Configuring the UPS for an EBM” on page 44.

10To change other factory-set defaults, see “Operation” on page 27.

NOTE: Dell recommends setting the date and time.

NOTE: At initial startup, the UPS sets system frequency according to input line frequency (input frequency auto-sensing is enabled by default). After initial startup, auto-sensing is disabled until manually re-enabled by output frequency setting.

NOTE: At initial startup, input voltage auto-sensing is enabled by default. After the subsequent startup, auto-sensing is disabled until manually re-enabled by output voltage setting.

NOTE: The internal batteries charge to 90% capacity in less than 4 hours (8 hours for 500W models). However, Dell recommends that the batteries charge for 48 hours after installation or long-term storage. If an optional EBM is installed, see the recharge time listed in Table 15 on page 58.
