Connecting Inverters/chargers/UPS to the battery unit while it is ON can cause big
sparks due to capacitors inside the connected device. This could cause serious injuries.
Use the appropriately sized cable for connected devices, calculated based on the rated
current of the battery and inverter as well as cable length and environmental
conditions.
Figure 5 connection terminals
Step 2. Connect the negative cable to the battery negative busbar and positive cable to
the battery positive busbar as shown in figure 5.
All used connection points should be a suitably tightened, ensuring good electrical
connection between the lug and busbar. A bad connection could cause serious damage
to the battery and inverter, and could void the warranty.

CANBUS connection.
Bms EM used CAN 2.0B @ 500 kbps. Connecting other devices operating at a different speed rate is
not allowed. For connection, please use twisted pair wires in a shielded cable to minimize RF
emissions.
The output of the BmsEm CAN transceiver is galvanically isolated.
