The cased controller is mounted externally. The uncased controller is mounted internally.
Choose a convenient spot away from high-voltage, high power cables and electronics.
Use 4-40 plastic screws to mount the cased controller to eliminate possible ESD input
path. Metal or plastic screws can be used on the 2x3 board if the green ground wire is
used. Metal screws are required on the 1x2 board if a separate ground wire is not used.
