		4	== Installation ==
		5
		6	The mounting area of the BMS Main X must be protected from mechanical particles (dust, dirt, large objects) and water.
		7
		8	The installation site must provide convenient access for subsequent connection to the device’s headers for connecting other system elements: contactors, temperature sensors, etc.
		9
		10	Overall and mounting dimensions of the BMS Main X are shown below.
