Installation
10 To change other factory-set defaults, see “Operation” on page 37.
11 If you installed an optional REPO, test the REPO function:
Activate the external REPO switch. Verify the status change on the UPS display.
Deactivate the external REPO switch and restart the UPS.
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. 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 68.
