Installing Signal Cables Between Lithium Battery Cabinets
•
Multiple lithium battery cabinets have been configured. This section uses three lithium battery
cabinets connected in parallel as an example.
•
The number of each lithium battery cabinet is determined by the parallel cable connection
mode. The master cabinet with a display is cabinet 1, the lithium battery cabinet connected to
the BCU_OUT port of cabinet 1 is cabinet 2, and the like.
1. Connect the BCU IN and BCU OUT ports of the BCU in each lithium battery cabinet to form a loop.
2. Connect the cable on EPO2 in lithium battery cabinet 1 to the cable on EPO1 in battery cabinet 2.
3. Connect the cable on EPO2 in lithium battery cabinet 2 to the cable on EPO1 in battery cabinet 3.
4. Remove the existing cable from EPO2 in lithium battery cabinet 3, and connect EPO2 in lithium
battery cabinet 3 to the EPO button contact in lithium battery cabinet 1 using a cable available in
the fitting bag.
