9.5 BCB Box
9.5.1. Overview
The BCB box contains a BCB and a BCB control board.
Vertiv provides the BCB box for use when the external battery installation is required. In this situation, The
BCB box is fitted as close as possible to the battery and connected to the UPS. Refer to Figure 9-1 , Table
9-5 and Table 9-6 for description of the BCB box and its components.
The BCB box protects the battery against overdischarge and overcurrent, and also isolates the UPS and
battery, thus reducing the risk at lowest for service personnel during the maintenance. The box inside has
connection bars for connecting the power cables from the UPS and batteries.
NOTE: The signal cables from the UPS to the BCB control board must be routed in a separate cable
trough and separated from battery power cables. The separate safety earth must be connected at the
UPS side.
