Installation
|
To start up the UPS:
1 Verify that the internal batteries are connected.
2 If an optional EBM is installed, verify that the EBM is connected to the UPS. Refer to the Dell
Online Rack EBM 10 kW Getting Started Guide for more information.
3 Verify that all load segment circuit breakers are in the ON position.
4 Switch the main utility breaker on.
The UPS LCD panel display illuminates. The Dell startup screen changes to the UPS status
summary screen. The UPS front panel display shows the flashing Standby icon
.
5 Press the On/Off button on the UPS front panel (see Figure 23).
After the startup is complete, the status icon changes to the appropriate icon based on the UPS
operating mode (see Table 4 on page 42).
6 On the UPS status control panel, press the button to check for active alarms or notices. Resolve
any active alarms before continuing. See “Troubleshooting” on page 84.
If there are no active alarms, a “No Active Alarms” message appears.
7 Verify 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 42).
8 If an optional EBM is installed, see “Configuring the UPS for an EBM” on page 60.
9 To change other factory-set defaults, see “Operation” on page 37.
10 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.
11 Charge the batteries.
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.
CAUTION: To prevent an UPS overload condition, connect one load at a time and make sure that each
protected device starts up completely before you connect the next load.
NOTE: Dell recommends setting the date and time for troubleshooting or warranty purposes.
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.
