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.
