2.9.3 Battery Cabinets #3 and #4
11. Repeat Steps 8, 9 and 10 for the additional battery cabinet(s).
2.9.4 Final Battery Cabinet Connections
12. When connections and polarity have been checked on each additional
battery cabinet, verify that there is one connection left unplugged in each cabinet
(Steps 7 and 10). In Battery Cabinet #1, reconnect the top right-hand tray to the
tray immediately below.
13. Move to Battery Cabinet #2.
WARNING
Before reconnecting the top right-hand tray to the
tray immediately below in Battery Cabinet
#2, measure the voltage between these un-
plugged connectors with a dc voltmeter. It is
expected that this voltage reading will be small. In
no case should the connection be made if there is
more than 5 volts difference.
14. If there is less than 5 volts between the connectors, plug them together.
15. Repeat Steps 13 and 14 for each additional battery cabinet, making
sure to measure the voltage between the unplugged connectors each time.
The uninterruptible power system is now ready for startup. See Section
III,
Operation.
WARNING: Do not close the battery circuit breaker until
instructed to do so in the startup procedure.
