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.
