10 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.

20 The mounting location must be protected from mechanical obstacles (dust, dirt, large objects) and water. Device placement should provide easy access for connection.
