7.5 Multiple UPS distributed bypass operation
7.5.1 Starting the distributed bypass system in normal mode
To start the distributed bypass system:
1 Unfasten the front door latches and swing the doors open on all of the UPS. If the UPSs contain
input breakers (CB1), verify that all input breakers are open.
2. Close all Module Output Breakers (MOBs).
3. Close all UPS input feeder circuit breakers.
4. If the UPSs contain input breakers (CB1), close all input breakers.
5. Close all UPS Bypass input feeder circuit breakers.
6. Close the doors and secure the latches.
7. Observe the UPS control panel displays becoming active, indicating logic power.
8. On any UPS, press the LOCK icon on the main screen. The Sign In screen is displayed. Use
operator password to log in (factory default password is 0101).
9. On the System Status screen, verify the UPS status is SHUTDOWN and the UPM status is
SHUTDOWN.
10. Close all battery breakers.
11. Verify no alarms are active on the ACTIVE EVENTS screen (found under LOGS).
12. Select CONTROLS on the main screen. SYSTEM CONTROLS screen opens up.
13. Select GO ONLINE. Command confirmation pop-up screen will show up asking confirmation for
the action. Select YES.
If Auto Bypass is enabled (factory default), the critical load is immediately supplied by the bypass
source in Bypass mode from all UPSs, until the inverter turns on and the UPSs transfer to Normal
mode. The status indicator on the UPS control panel indicates the UPS is in Bypass mode. If Auto
Bypass is not enabled, the UPS outputs remain off until the UPSs transfer to Normal mode.
The rectifier and inverter turn on. The inverter continues to ramp up to full voltage.
Once the inverter reaches full voltage, all UPS output contactors (K3) close and the bypass circuits
open. Power is now supplied to the critical load in Normal mode from all UPSs. It takes approximately
one minute for the UPSs to achieve Normal mode.
The ONLINE status indicator is illuminated. The UPS status indicates ONLINE.
The UPM status is ACTIVE on MODULE CONTROLS screen.
7.5.2 Starting the distributed bypass system in Bypass mode
If the inverter output of the distributed bypass system is not available and the critical load needs to be
energized:
CAUTION
In Bypass mode, the critical load is not protected from commercial power interruptions and
abnormalities.
1 Unfasten the front door latches and swing the doors open on all of the UPS. If the UPSs contain
input breakers (CB1), verify that all input breakers are open.
2. Close all Module Output Breakers (MOBs).
3. Close all UPS input feeder circuit breakers.
4. If the UPSs contain input breakers (CB1), close all input breakers.
