Physical size

Battery Connection Unit (BCU) can be installed in cabinets with widths of 600mm and depths of 400mm and 600mm. BCU has a maximum height of 1.5U (67mm).

BCU contains 2 to 5 circuit breakers, each with ratings of 100A and 200A.

Alarm output

The BCU will generate an alarm if a battery circuit breaker is off. This alarm shall be possible to connect to the connector board for display in the Controller. It shall be possible to combine the alarms from 2 BCUs to generate a single alarm in the controller. It shall also be possible to combine the alarm from the BCU with an
