Check that the positive and negative wiring of the battery RACK and the DC/DC power
cable are correctly wired.
•
Check that the battery RACK, DC/DC and battery terminal cabinet power circuit wiring
should not be loose.
•
Check that there are no short circuits between the positive and negative terminals of the
converging branches in the BCP.
•
Check that the external supply cable on the AC side of the BSP is wired correctly.
•
The circuit breaker in the BSP and the load switches SWITCH1 & SWITCH2 on the DC/
DC should be in the open position.
•
Check for coolant leaks in the battery PACK and in the cooling ducts.
•
Confirm that the PCS DC side is correctly connected to the BCP DC side cable of the
BESS to avoid a reversal of the connection cable order.
