2.6 Connection Of External Battery Circuit-Breaker (BCB
Table 2-1 provides recommended BCB rated current and minimum connection cable Cross Sectional Area (CSA).
Table 2-7 Reference table for selection of BCB rated current and connection cable CSA (minimum recommended)
Note: the minimum CSA is adequate for batteries located up to 5 meters from the UPS. For longer cable runs, the CSA shall be increased so
that the voltage drop remains less than 1% in order not to affect the battery run time significantly.

Note:
-It is recommended to use a DC moulded-case circuit breaker (MCCB) appropriately rated to open the kA fault current of the
battery at the nominal battery voltage. Applicable connections between the battery, BCB and UPS are shown in Figure 2-3, 2-4
and 2-5.
