CAUTION It is possible to damage the display when tightening the screws, as there
is not much room between the upper fastening holes and the exposed
display component. Be particularly careful when using a cordless drill.
NOTE Select the size and type of the fastening screws according to the wall
material (wood, stone, etc.). Even though using all four screws is
strongly recommended, the HMT130 enclosure fastening holes are
initially covered with a thin plastic membrane, so less than four screws
could be also be used without sacrificing the ingress protection (IP) class
of the enclosure. The diameter of the fastening screws is typically
between 3.5 and 4 mm.
