2.3 Front Panel
1) Chassis mounting ears: For product installation and fixation, it can be
installed in a 19-inch standard cabinet or an anti-vibration iron frame.
2) Chassis handle: easy to carry, move and install.
3) Switch: BMS switch, when it is turned off, the BMS can be put to sleep and the
charge and discharge MOS transistors will be turned off at the same time;
normal operation will be restored after it is turned on.
Note: Please do not turn on the system switch when the product is not in
use to avoid self-consuming the lithium battery.
4) Switch: BMS switch, when it is turned off, the BMS can be put to sleep and the
charge and discharge MOS transistors will be turned off at the same time;
normal operation will be restored after it is turned on.
Note: Please do not turn on the system switch when the product is not in
use to avoid self-consuming the lithium battery.
5) Reset switch: When the battery is abnormal or dormant, the reset button can
be used to restart and wake up the battery to ensure the stable operation of
the system.
6) CAN COMM：
BMS supports the function of CAN communication for battery pack uploading，
baud rate of 500K. CAN communication interface adopts 8P8C network cable
interface. It can communicate with inverter or CAN TEST through CAN interface.
When the battery pack is connected, RS485 communication is connected，the
data, status and information of the battery pack can be uploaded to inverte
through CAN communication.
CAN communication interface definition:
7) RS485 COMM
The BMS has RS485 communication for battery pack collection, and the
baud rate is 9600bps. RS485 communication interface adopts 8P8C
network cable interface. RS485 pin interface definition (RJ45-8P8C)
