Connecting Batteries
Caution: Review and observe precautions outlined in Section 2, Safety, before proceeding.
Confirm the battery polarity matches power system
Connecting Batteries
Step Action
Measure the battery string voltage. Temporarily use the following M2 menu path to set the plant voltage to match the
measured battery string voltage (+/- 0.05V).
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 13-5 and 4-1 through 4-4.)
When all battery strings have been placed on line, use the following M2 menu path to set the plant voltage back to
the desired Float Voltage.
Observe that all rectifiers share the battery charging load current. Verify this using the following M2 menu path:
If any installed rectifiers are missing or are not sharing load, perform the following M2 reboot process to have all
the rectifiers reinitialized into the system.
When the current has stabilized or dropped to a level equal to several amperes per string, proceed to the next
section.
