Dimensions
For fixing the flush mount version instrument to the panel,
use the fixing devices supplied, by inserting them in the side
groves of the enclosure and tighten the screws.
For safety reasons, place an external fuse protection at the
input voltages, and use adequate cables for the working
voltages and currents, with a section from 0.5 to 2.5 mm
