10.2.2Manual Start
1.Perform the Initial Setup procedures.
2.On SSBM, turn the SYSTEM MODE key switch to BYPASS momentarily.
If a bypass source is available when you turn the SYSTEM MODE key switch to BYPASS, the critical load is immediately supplied by the bypass source in Bypass mode until the the UPMs are available and the SSBM has been manually transferred to Normal mode. The status indicators on the SSBM monitor screen indicate when the Parallel Capacity/Redundant system is in Bypass mode and Normal mode.
3.Observe that CBP and FBP have closed.
4.On first UPM, close CB1.
5.Observe UPM monitor screen becoming active as an indication of logic power.
6.Verify UPM is shown on the SSBM mimic screen.
7.On first UPM, set BATTERY switch to NORMAL.
8.On first UPM, set MODE switch to NORMAL.
9.On first UPM, turn the START switch to the right for 2 seconds and then release.
10.When UPM Battery Disconnected alarm and notification is received, close first UPM battery disconnect breaker.
11.On first UPM, turn the START switch to the right momentarily.
The rectifier turns on, then the inverter turns on. When the inverter reaches full voltage, K3 closes. Logic power is supplied and the UPM is ready to supply power to the critical load. It takes less than 1 minute for the UPM to achieve Normal mode.
12.Start remaining UPMs by repeating steps 4 through 10.
13.On SSBM monitor screen, check for On Bypass, UPMs Ready message.
14.If message appears, turn the SSBM SYSTEM MODE key switch to NORMAL momentarily.
15.Observe that breaker CBS closes and breaker CBP opens. System is now in Normal mode, with the critical load being supplied power from the UPMs.
