NOTE 1
Verify that the total equipment ratings do not exceed the parallel system capacity to
prevent an overload alarm.
NOTE 2
Refer to the Eaton® BladeUPS® Maintenance Bypass Module User’s Guide for MBM
operation information and startup procedures.
NOTE 3
The load connector breaker controls the load connector only, not the output power cord.
To start up a parallel (or parallel-ready) system:
1.
Verify that all UPS circuit breakers are in the OFF (O) position.
2.
Switch on utility power where the UPS is connected.
3.
Remove the breaker ties from the circuit breakers.
4.
Switch the UPS input circuit breaker on each UPS to the ON (|) position.
5.
Wait for the front panel display on each UPS to illuminate.
The
indicator flashes on each UPS.
6.
Check each UPS front panel display for active alarms or notices (other than “Batteries Disconnected”).
Resolve any active alarms before continuing. See “Service and Troubleshooting” on page 133.
7.
Switch all UPS battery circuit breakers to the ON (|) position.
8.
If optional EBMs are installed, switch all EBM battery circuit breakers to the ON (|) position.
9.
Verify that the “Batteries Disconnected” alarm on each UPS has cleared. Verify that no other alarms
appear on any UPS front panel display.
If an
indicator is flashing on any UPS, do not proceed until all alarms are clear. Check the UPS status
from the front panel to view the active alarms. Correct the alarms and restart if necessary.
10. On any UPS, press any button on the front panel display to activate the menu options, and then press
the button until the TURN UPS ON/OFF menu displays.
11. Press the
button to display the TURN SYSTEM ON option; press the
button.
12. Confirm the selection. Press and hold the
button for three seconds, until the UPS stops beeping.
Verify that the
indicator illuminates solid on each UPS, indicating that the UPS is operating
normally and any loads not connected through the load connector are now energized.
If the
indicator on any UPS is flashing, do not proceed until all alarms are clear. Check the UPS status
from the front panel to view the active alarms. Correct the alarms and restart if necessary.
NOTE
For a parallel-ready system (a single UPS installed to be part of a future parallel system),
set the Parallel Operation Settings / Parallel Operation Mode to “Capacity Mode” to
prevent unnecessary alarms (See table 13 on page 100, Parallel Operation Settings).
Each UPS should be in Normal mode. By default, Normal mode operates on the High Efficiency setting (
see “Normal Mode” on page 101).
13. To energize loads connected through the load connectors, switch all load connector circuit breakers to the
ON (|) position.
