6 +To perform the protection functions, the BMS must be able to disconnect the battery from the load and charger. To do this, **at least one contactor** able to break the load and charge circuits must be connected to the BMS.

8 +Before use, **configure the system**. Proper operation of the BMS is possible only if it is correctly configured.

6 -The mounting area of the BMS Mini must be protected from mechanical particles (dust, dirt, large objects) and water. The BMS Mini is recommended to be placed close to the cells it controls, but away from high current circuits to reduce interference to measuring circuits and increase overall reliability of installation.
