They can be installed to face either the top or bottom of the unit. The DT20-M comes with surface mounting ears and preassembled insert bars. Position the ears centrally on each side of the unit, aligned with the threaded holes on the insert bars, facing either up or down as required, and secure them using the 4x M3x6mm screws provided in the package. For surface mounting of a standard DT20, the optional surface mounting kit DT-SMK is available.
