2.4.8 Battery BMS Connection
There are two serial communication options for the battery BMS (Battery management system)
of the A-ES series:
- Controller Area Network (CAN) 1 communication (e.g., for BYD battery)
- RS-485 communication (‘485 network’) (e.g., for LG battery)
Select the corresponding communication according to the battery type installed.
The BMS uses a #22 AWG, 600V insulated cable.
Run the cables through the BMS conduit
port. Tighten conduit tting of BMS port.
For CAN1 battery, for example BYD, please connect BMS cables to
CAN1 terminals as shown in position 2 in the gure.
For LG battery, please connect BMS cables to 485-1 terminals and connect enable signal
cables to LG _EN+ & LG_EN- as shown in position 1 and 3 in the gure.

Use the correct wire ferrule from the accessory box. Crimp the ferrule
onto the conductor core tightly, as shown below.
Note:
Make sure the cable jacket is not
locked within the wire ferrule’s
crimped section. It is not necessary
to utilize a wire ferrule if using a solid
(non-stranded) conductor, just remove
the insulation.
