2.5 Battery Control
Battery temperature sensor cables are connected between UPS auxiliary terminal block X3 BCB, the
Battery Temperature sensor and the battery as shown in Figure 7.
Cables connected to X3 BCB must contain a protective earth wire or a shield, be segregated from
power circuits, double insulated and of a typical 0.5 to 1mm2 cross section area for maximum runs
between 25 and 50 meters respectively. The shield should be connected to the protective earth of the
battery cabinet or battery breaker, not at the UPS.
