5 5  1. Connect the BMS Main 2.1 to the on-board CAN network. Observe the rules for connecting CAN devices. If the BMS Main 2.1 is the last device on a bus, close pins 1-2 on the P21 jumper, otherwise leave the jumper on pins 2-3.
6 6  1. Connect a power supply to the P1 header. It is not recommended to power the BMS Main 2.1 from the battery only, since at a critical discharge of the battery, it is not possible to turn on the BMS and close the charging contactor.
