Mounting the Units
2.2.2 Mounting the Transceiver Unit (TU)
The Transceiver Unit should be installed in a dry place and consideration should be given to acces-
sibility for servicing. It is important to provide suffi cient airspace below, above and in front of the unit
for adequate air circulation through the cooling fi ns. The drawing below shows the outer dimensions,
mounting possibilities and the minimum distance to other objects, as well as a drilling plan.
