Surface mounting
The surface mounting ears allow the device to be
mounted on top or under a surface, desktop or
podium, or vertically on a wall or partition. 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.
Rack mounting
Up to two units can be rack-mounted in a single 1U
rack space with the optional rack kit DT-RK19.
