3.2.4.2 Installation of mast and mounting of sensors
The mast is pre-assembled, still horizontally on the ground in accordance with dimension sketch
shown in Figure 11. Hereby care has to be taken that the admissible clamping zone is not exceeded
(indicated by an upper and lower mark with red stripes in between for each section). The mast’s
nominal length is gained when clamping the sections at their lower marks. The base plate with its
centre pin is screwed to the lowest section’s bottom.
Figure 6: Clamping zone of mast sections are indicated by red stripes printed on the mast sections.
Sensor arms (a one-sided, a two-sided and an U-cross arm), sensors (temperature, relative humidity,
net radiation, wind speed and wind direction), lightning rod, antenna are equally pre-assembled
according to the individual system configuration (see Table 3 and Figure 7 to Figure 11). Connect the
antenna cable to the antenna and use self-amalgamating tape to prevent water entering the
connector. Use cable ties to fix all sensor cables to the mast/arms and lead them to the lower end of
the mast, where at a later stage the steel enclosure will be mounted.
Figure 7: Mast, sensors, cables and guys are pre-assembled before the mast is erected.
