Connecting Batteries
Step Action
1 Turn the system OFF. Turn the rectifiers to STBY. Open
the rectifier circuit breakers and system load circuit
breakers, if equipped.
2 Connect the batteries to the system. Choose the appropriate
method:
• Install the battery fuses and alarm fuses, or
• Close the battery circuit breakers, or
• Set the battery contactor board switches from forced open
to normal state, or
• Connect the remaining battery conductors. (See Figures
15-5 and 4-1 through 4-4.)
3 Turn the system ON. Turn ON all rectifiers. Close the
rectifier output circuit breakers (if equipped).
4 Observe that all rectifiers share the battery charging load
current. When this current stabilizes or drops to a level equal
to several amperes per string, proceed to the next section.
