power supply can be interrupted by means of a separate isolator or power
switch. We recommend using overvoltage protection for all devices.
2.5.2
Mounting on a flat surface
Before operating the device on a flat surface, such as a table, stick the
supplied casing feet onto the bottom of the device, with approx. 0.8 in (2 cm)
of space from the corners.
If necessary, remove any dirt from the bottom of the device where you
