1. Cables connected to X3 BCB must 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.
2. Battery temperature sensing cables must be less than 10 m long.
3. 30 and 40kVA UPS models fitted with internal battery and any UPS models fitted with Battery Start kit contain an internal UPS
battery contactor for automatic connection and disconnection of the batteries and the battery circuit breaker undervoltage coil is
not used. Refer to 2.5 - Battery Control for details.
CAUTION
!
Leave terminals open if the corresponding facility is not used. The commissioning engineer
must program the UPS accordingly (e.g., disable battery temperature compensation, enable
internal battery contactor)
2.6.1 Battery Temperature Sensor—Optional
The optional external battery temperature sensor kit, supplied separately from the battery circuit
breaker, contains one probe and one temperature transport board as illustrated in Figure 26. It is
connected to the UPS Monitor Board (either directly or in case of multiple sensors, through the bat-
tery circuit breaker board - see Figures 26 and 27).
