2.3 Connection Interface
2.3.1 Overview of the Connection Area
2.3.2 Start
1ON
For multiple battery Modules in series , long press (more than 5 seconds) Start button of the High-voltage
box (which is connected to the inverter ) , the normal LED on the front panel will illuminate.L1 to L5 shows battery
SOC , L6 shows battery status . The high-voltage box which contains the BMS will automatically encode and assign
an ID to each battery module. The battery can then operate.
2OFF
Press Start button of High-voltage box (Which connect with inverter) more than 5s , LED will flash in the front panel
and then release the button,the principal battery module will shut down after all subordinate packs shut down (Sleep
mode).
Tip:If the system does not work, keep the internal DC switch on the battery cluster closed

UM0042_Ai-HB 2.56LG_EN_V01_0223 9
2.3.3 Link Com Port
The Link Com Port is the interface between the high-voltage box and the inverter. The inverter retrieves the battery data such
as SOC, DOD, charge current via this connection.
CAN / RS485/RS232 Communication Terminal (RJ45 port),
CAN/RS485 connect to inverter, follow CAN / RS485 protocol.
RS232 Communication follow RS232 protocol, for manufacturer or professional engineer to debug or service.
2.3.4 Link Power/Link in/Link out
Link Power/Link in/Link out are used for the communication between battery piles. The battery pack close to the
inverter as the master, others are the subordinate pack.
