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.

11 (((
12 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.

Admin 1.1 20 == Installation ==
21
Admin 2.1 22 The mounting area of the BMS Main X must be protected from mechanical particles (dust, dirt, large objects) and water.
Admin 1.1 23
24 The installation site must provide convenient access for subsequent connection to the device’s headers for connecting other system elements: contactors, temperature sensors, etc.
25
Admin 2.1 26 Overall and mounting dimensions of the BMS Main X are shown below.
