3.3.2 Battery Control
The BCB is controlled by the BCB control board. Both are located within the BCB box. This board controls the circuit
breaker's undervolts release coil and also provides a path for the circuit breaker auxiliary contacts to signal the circuit
breaker status back to the UPS control logic.
All connections between the BCB control board and the UPS module are made through the auxiliary terminal block
X3 located on the base of the UPS Cabinet. X3 is shown in Figure 3-8 and described in Table 3-8.
