Starting a Parallel System
To start a parallel system (see Figure 32 on page 49):
1.
Verify that all UPS circuit breakers are in the OFF (O) position.
NOTE
The load connector breaker controls the load connector only, not the output power.
2.
Verify that all UPS power cords are plugged in.
3.
Verify that all redundant signal cables are connected.
4.
Switch on utility power where the UPSs are connected.
5.
Switch the UPS input circuit breakers on each UPS to the ON (
|
)
position.
6.
Wait for the front panel display on each UPS to illuminate.
The
indicator flashes on each UPS.
7.
Check each UPS front panel display for active alarms or notices
(other than “Batteries Disconnected”). Resolve any active alarms
before continuing. See “Troubleshooting” on page 119.
8.
Switch all UPS battery circuit breakers to the ON (
|
) position.
9.
If optional EBMs are installed, switch all EBM battery circuit
breakers to the ON (

10.
Verify that the “Batteries Disconnected” alarm on each UPS has
cleared. Verify that no other alarms appear on any UPS front panel
display.
If the
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.

On any UPS, press any button on the front panel display to activate
the menu options. Select TURN UPS ON/OFF, TURN SYSTEM ON,
