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.
7 +
8 +Before use, **configure the system**. Proper operation of the BMS is possible only if it is correctly configured.
9 +
10 +It is not recommended to use the system in batteries formed by several series of cells connected in parallel. To increase capacity, it is recommended to connect several cells in parallel groups, and then connect the groups in series.

14 +The BMS can be connected to batteries with life-threatening and health-hazardous voltage levels. When working with high-voltage batteries, observe electrical safety regulations, use safety glasses, protective clothing, insulated tools and appliances. To prevent the damage of device avoid electrostatic discharges while working with the battery.

6 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.
