be split into two partitions where an active partition must always be lower than 2GB,
formatted to FAT32 with 512B clusters.

7. Application information
Installation of the sensor with a separate evaluation unit:
First of all, it should be determined which type of installation is to be used, whether
the mounting is to be behind the electronics or under the electronics. The mounting
corner is fixed to the wall with screws. The evaluation unit is mounted to the fas-
tening and wired. The cables should form a suspension so that no condensation
water runs into the housing.
