• The cable of the J2 BCB port must be routed separately from the power cable. It uses the dual-insulat-
ed shielded cable (the CSA is generally 0.5 mm

~ 1 mm

when the max. wiring distance is 30 m), and
the UPS side of the shielding coat must be connected to the enclosure reliably.
Caution
If the corresponding functions are not required, just do not connect corresponding terminals.
9.6. Battery Cabinet
The BCB cabinet contains batteries, BCB and a BCB control board.
Vertiv provides the BCB cabinet for battery backup use. Refer to Figure 9-3 , Table 9-8 for description of the BCB
cabinet and its data.
The BCB cabinet 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 cabinet inside has
connection bars for connecting the cables from the UPS.
• 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.
