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 4mm.
