Figure 6-4 Installation hole dimensions for floor mounting of BCB box of 300/400kVA UPS (unit: mm)
The battery circuit breaker (BCB) box contains a BCB and a BCB control board (ULK366SC1).
The BCB box is fitted as close as possible to the battery and connected to the UPS, as illustrated in Figure

Figure 6-5 BCB box connection
Note: The control cables from the UPS to the BCB control board must be made using the accessory cable of the BCB, which is a shielded cable located in a separate conduit to that containing the battery power cables. The cable shield must be earthed to prevent induced noise affecting the control operation, and a separate safety earth must be connected between the UPS and BCB box.
6.10 Battery Temperature Sensor (Optional)
A battery temperature sensor (model: TMP12Z) supplied separately from the BCB is connected with the UPS logic through the BCB control board. For the connection, see Figure
With this feature fitted, the nominal float voltage supplied to the battery is adjusted so as to be inversely proportional to the ambient temperature of the battery cabinet or battery room. This prevents the battery being over charged at high ambient temperatures.
