The default functions of J6 and J7 are the ports for BCB tripping and BCB status, connect J6-1 and
J7-1 to BCB tripper, the port J6-1 can provide a driver signal (+24VDC, 20mA) to trip the battery
breaker when EPO is triggered or EOD (end of discharge) happen. Connect J6-2 and J7-1 to BCB
auxiliary contact NO, connect J7-1 and J7-2 to BCB auxiliary contact trip NO, the UPS would detect
the BCB status, when BCB is closed, it indicates batteries are connected, when open, it alarms
batteries not connected. The port diagram is shown in Figure 2-25, and the description is shown in
