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 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, set BATTERY switch to ENABLE.
5. On first UPM, turn the MODE key switch to NORMAL for three seconds.
6. Confirm the UPS breaker CB1 has closed by verifying breaker position on LCD
mimic screen.
The rectifier and input/rectifier cooling fans blowers should be running.
7. Confirm UPS Battery Breaker CB2 (MBB) has closed by viewing breaker
position on LCD Mimic screen.
NOTE: If CB2 is a manual battery breaker, manually close CB2 after UPM
Battery Disconnected alarm and notification is received.
The inverter and output/inverter cooling blowers turn on. When the inverter reaches
full voltage, UPS breaker CB3 closes. It takes less than 1 minute for the UPS to
achieve Normal mode. If UPS is not in Autorestart, turn the MODE key switch to
NORMAL for three seconds to transfer to Normal mode.
