4--5 Powerware BPIV Parallel Cabinet Installation and Operation
164201409 REV. B 101503
NOTE: If Auto Start has been enabled, the UPMs and Parallel Cabinet start and
power up to NORMAL mode automatically once CB1 is closed.
11.
On each UPM, close Input breaker CB1.
12.
Select NORMAL from the System Control menu on any UPM.
Normal Mode Requested appears on the screen. All UPMs are commanded to turn
on. If the bypass source is available, the Parallel Cabinet bypass contactor K4 closes,
and the critical load is immediately supplied by the Parallel Cabinet bypass source, in
Bypass mode. The
BYPASS
status indicator on the Parallel Cabinet is illuminated.
13.
Observe the following messages appear sequentially on the PPU status line:
WAITING FOR INPUT
DC STARTING
INVERTER STARTING
SYNCING
ONLINE
The rectifier and inverter turn on at each UPM. When the all inverters reach full
voltage, the UPM output contactors close and the Parallel Cabinet bypass contactor
opens, supplying power to the critical load in Normal mode. It usually takes less than
1 minute for the Parallel System to achieve Normal mode.
14.
The Parallel System is now operating in the Normal mode and the
NORMAL
status indicator on the Parallel Cabinet and all UPMs is illuminated.
4.4.2
Starting the Parallel System in Bypass Mode
If the Inverter Output of the UPMs are not available and the critical load needs to be
energized, perform the following procedure:
WARNING:
In Bypass Mode, the critical load is not protected from commercial power
interruptions and abnormalities.
1.
Ensure the UPM circuit breakers and switches are set as follows:
UPM Input Breaker (CB1) OPEN
UPM Battery Breaker (CB2) OPEN
UPM Maintenance Bypass Switch UPS
NOTE: If Auto Start has been enabled, the UPMs and Parallel Cabinet start and
power up to BYPASS mode automatically once the bypass input feeder
circuit breaker is closed.
2.
Close the Parallel Cabinet bypass input feeder circuit breaker.
3.
Close all UPM input feeder circuit breakers.
4.
If UPMs are dual feed, close all UPM Bypass input feeder circuit breakers.
5.
Observe monitor screens on all UPMs becoming active as an indication of
logic power.
6.
Press the System Control pushbutton on any UPM. The System Control
screen appears on each UPM.
